Some characters are subject to a strange fluctuating sense of maturity depending on plot necessity, mostly because animated characters can have [[ArtisticAge abstract designs and lack obvious visual cues]] (especially when the characters are non-human). We're only left with the personality of the character, which tends to suggest their age. DawsonCasting, leading to a blurring of the line between adults-playing-adults and adults-playing-teenagers, is responsible for several live-action examples.

A TV character may be implied to be some sort of ''adult'' compared to other characters who are clearly "kids", or vice versa, but this is largely an illusion in case the writers still want them in plots to which a younger audience can more easily relate. The only nominally-aged character is usually the lead, and this is only useful to make his same-aged audience feel better, since he will probably [[NotAllowedToGrowUp not be allowed to get older]].

Occasionally, characters are given specific ages along with more obscure and extensive biographies, but are ultimately ruled by audience appeal, CastSpeciation, and personalities that fit into the mean age of the audience. Information that runs counter to that turns into the ImprobableAge issue, and may be tweaked in other places.

Compare MistakenAge.



[[folder:Anime and Manga]]
* ''Manga/{{Berserk}}'': The ages of the characters--and especially of the three main ones--has been a pestering question among the fandom since the character designs can be deceptive and the sparse information given leaves much to interpretation. Guts' age, at least, can be known at certain points in the story based on the number of years time-skipped since his birth. Unfortunately, although Casca says that she was twelve when Griffith took her in, she does not say how long ago that was and Griffith's exact age is not mentioned at any time. Everyone's guesses vary widely both on specific ages and on seemingly simple questions such as who is older or younger than who. An official guide book released in 2016 included the ages of major characters as of episode 347 (Guts, 24; Griffith, 24; Casca, 24; Serpico, 20; Farnese, 19; Rickert, 19; Isma, 15; Isidro, 14; Schierke, 13), but this raises as many questions as it answers since it sometimes leads to ImprobableAge, goes against a characters' appearance and relationship with other characters, and/or leads to contradictions in the timeline. For example, if you accept that Guts is 24 now, then following the timeskips backward Farnese would have been 14 when she led to Holy Iron Chain Knights to the pool of blood left behind by the Eclipse. Not only did she look older than that at the time, but the dialogue in the later flashback to her childhood establishes that she was 16 when she burned the Vandimion mansion and got banished to a convent, the event which led to her being put in charge of the [=HICKs=] in the first place. Logically she would have to be at least 21 to Guts' 24 in order for these things to be reconciled. Because of this and other probelms, including speculation that these ages may have been decided by some editor rather than Miura himself, there's a risk that many fans will simply [[FanonDiscontinuity ignore the official ages]] and continue to bicker just as they've always done.
* Mireille of ''Manga/DotHackLegendOfTheTwilight'', who can be very knowledgeable at times, sometimes lord it over others, and sometimes just be cute and vulnerable. [[spoiler: She actually turns out to be the four-year-old daughter of an [[IdenticalGrandson identical character]] from the first game, using her mother's file, and one of the other girls in Shugo's {{harem}} is her home tutor, explaining some of it.]]
* Levi (and a few others) from ''Manga/AttackOnTitan''. Levi is noticeably smaller than many characters, including the adolescent protagonists, and looks younger than a few of the trainees, but in reality he has to be anywhere from three to ten years older than them. WordOfGod says he's "[[OlderThanTheyLook surprisingly old]]", later clarifying the age is past 30.
* ''LightNovel/{{Baccano}}'' makes it rather difficult to determine Ennis's physical ''or'' chronological age, as her origin is [[ArtificialHuman somewhat]] [[OurHomunculiAreDifferent complicated]] and not too many details are given on her timeline in either the anime or LightNovels beyond three tidbits: she was around before the commercialization of radio (with the given [[HistoricalFiction setting]], means she can be anywhere from eight to two hundred and nineteen), she's physically the same age as her "mother" was when she unwillingly "donated" some of her cells (nothing is given about this girl/woman other than that she was female), and that she identifies Firo on sight as "around the same age as her, or a little younger" (which, given that Firo's an eighteen-year-old [[OlderThanTheyLook regularly mistaken to be as young as fourteen or fifteen]]).
* While she's clearly older than Tsutomu, the age of the title character of ''Anime/BirdyTheMighty'' was never stated in the OVA or ''Decode''. In the OVA series, Tsutomu chastises Birdy for drinking alcohol due to a combination of the possibility of getting drunk while on duty and her being underaged, which given the legal drinking age in Japan is 20, suggests Birdy in the OVA series is at the oldest 19. However, in ''Decode'', Birdy's age is easier to determine as flashbacks to her are shown when she was 10, a friend of hers while she was that age says he hasn't seen her for 14 years, and Tsutomu only reprimanding her for getting drunk, but not her age, suggests at the youngest, she's 24 there.
* Anime/CaptainHarlock: He is said to have a reputation that would have to have been years in the making. He usually seems to appear no older than about thirty. In ''Endless Odyssey'', one of his old comrades assumes that "he must be dead by now" and is genuinely suprised when he shows up, many years after their old adventures (Endless Odyssey is allegedly meant to pick up many years after the 1978 series left off). Also, if one were to even attempt to fit all or even some of his appearances into a coherent timeline (especially ''Arcadia of My Youth'', ''Manga/GalaxyExpress999'', the 1978 series, and ''Endless Odyssey''), you would end up with a Harlock that appears to have been active for decades.
* This was the case for most of the 00 cyborgs in ''Manga/{{Cyborg009}}'', as Ishinomori never gave them established ages- with the exception of 009, who was 18 and 001 who was of (vague) infant age. The anime adaptations settle on 007 being the oldest (except for the '60s incarnations which made him a 9-year old KidAppealCharacter) and in his '40s, 006 being a little younger than that, 005 and 004 either being in their late '20s or early '30s, 008 being in his early '20s, and 002 being in his early '20s or being 18 like 009. 003 either winds up younger than 009 in the earlier anime adaptations, being 16 or 17, or she's older in the '01 incarnation (physically 19, but chronologically ''much'' older due to being cryogenically frozen in the '60s).
* In ''Manga/FairyTail'', Natsu's age hasn't been revealed even though most other members have a known age. Because he couldn't pass through Freed's barrier in the Battle of Fairy Tail, he is either 80+ years old (which seems a bit weird since he obviously has aged as he looked like a kid 6 years ago and a teenager now) or a stone statue (which makes even less sense). In terms of personality and appearance, he is probably supposed to be seen as being Lucy's age (17 years), as he looks a bit younger and acts more immature than 18-year-old Gray. [[spoiler:Later chapters reveal that he is at least ''400 years old'', a fact that he himself is unaware of. Natsu is actually Zeref's dead younger brother brought back to life as a demon powered by Etherious. It later turns out that he is ''physically'' as old as he looks, but by technicality he and the other true dragon slayers are 400 years old due to being born 400 years ago and sent forward in time via the Eclipse Gate. Also, the reason he and Gajeel couldn't pass through Freed's barrier is possibly because [[ItMakesSenseInContext they had their dragon parents in their bodies at the time]] and they were probably older than 80]].
* None of the ''Manga/GunslingerGirl'' cyborgs have a given age. Henrietta seems to be between eleven and thirteen, while Triela is a little older, and Petra is the oldest and has a romance with her [[TheHandler handler]] but is still a teenager. To make it more confusing they seem to be [[NotAllowedToGrowUp stunted]] at the age they were Conditioned at and possibly years have passed between their backstory and the final chapter, so that leaves it vague what their biological ages are.
* Played with in ''Anime/HareGuu''. When attending [[{{Eagleland}} The City's]] school, Haré immediately notices all the kids are separated by grades. His own school is a literal [[TwoTeacherSchool one-teacher]] and his homeroom consists of ''every'' non-adult in the series, including teenagers. [[note]]Which incidentally is TruthInTelevision for extremely low population density areas; a single teacher is able to give individualized assignments for each student based on their age, when there's only a handful of them to begin with.[[/note]]
* Mikuru Asahina from ''LightNovel/HaruhiSuzumiya''. Although she looks like a {{moe}} teenager, when Kyon asked her how old she really is after she revealed her true origin and purpose, she merely responded, "That's classified."
* ''LightNovel/HighSchoolDXD'' is rife with this, thanks to reincarnated devils having their aging slow down dramatically from the moment they're reborn. Rias is a high school senior, but as a pure-blooded devil it's plausible she's pushing quadruple digits. Akeno looks exactly the same age, but is significantly younger. Issei, Asia and Xenovia are exactly the age they look thanks to having been recently reincarnated, but Kiba is heavily implied to be decades older despite being in the same school year. And all three of them are stated to be much younger thank Koneko, a tiny underclassman who could well be over a century old, and Gaspar, whose {{Dhampir}} nature only further muddies the waters.
* ''Manga/InuYasha'':
** Kikyo is accepted to be in her mid-to-late teens, but her exact age is uncertain. The ''[=InuYasha=] Profiles'' book states that she was eighteen when she originally died, whereas [[WordOfGod Rumiko Takahashi]] said she was "around seventeen" when it happened.
** Likewise, the exact ages of all {{youkai}} and [[HalfHumanHybrid hanyou]] characters is left deliberately ambiguous.
* ''Anime/KaitouJoker'' seems to be a world of characters with ambiguous ages.
* Lampshaded in ''Manga/KillMeBaby'' when Yasuna say's that she's "probably in high school".
* ''Manga/{{Kobato}}''. She certainly ''acts'' a lot younger than a teenager, but from her design and the way other characters treat her she seems to be at least twelve and probably not old enough to be in high school.
* ''Franchise/LupinIII'': The characters are certainly adults, but beyond that it's anyone's guess. The fact that they have been having adventures since TheSixties can be ignored since the series runs on ComicbookTime. However, Lupin himself is canonically the [[IdenticalGrandson grandson]] of Literature/ArseneLupin, who first appeared over a century ago, already an adult. At this point, the timeline would make a lot more sense if it were called Lupin the Fourth or even Lupin the Fifth.
* Satsuki Hyoudou from ''Manga/MaidSama''. Despite looking like a teenager, she is actually 30 years old.
* ''Manga/OnePiece'':
** Coby appears to be child much younger than Luffy (who is 17 at the beginning of the story), but enlists in the marines as soon as he's saved [[spoiler: and then apparently goes through puberty and has a growth spurt by the next time he is seen.]]
** Shakky is an even better example. She mentions that she was chased by Garp and stopped pirating 40 years ago, which would probably make her more than 60 (at least not a day under 55). But she looks like she is in her late twenties or early thirties, and the characters have questioned her age several times. So she could be anywhere from 60 to more than 100 since it would be unrealistic for an older woman to look like a 30-year-old no matter what.
* ''Anime/{{Pokemon}}'':
** Unlike the games, the protagonist (Ash) is given a clear age of ten years old, however, the Pokémon themselves are a mystery. Meowth is apparently an adult but everyone else is up in the air. Do Pokémon age when they evolve? If a baby Pokémon never evolves are they always considered a child? Is Donphan a ManChild or a [[HugeSchoolgirl large child]]? Bulbasaur and the other first-stage Pokémon are largely assumed to be 'child Pokémon', but an early joke had them drunk and their species can breed. In another episode, an elderly Treecko was seen. It's never specified whether Pikachu is an adult or whether he's a KidHero like his trainer. Pikachu in ''Anime/PokemonIChooseYou'' [[spoiler:[[TalkingAnimal speaks]] for the first time and has a rather high pitched, childish voice]], implying that he's considered a child by Pokémon standards.
** Most characters besides the protagonists have no age. Brock is fifteen according to supplementary material and Misty is ten like Ash, but unless their ages are given in the games it's unlikely anyone's age is given in the anime. May, Dawn, Iris, Serena, and Clemont all seem the same age as Ash but Cilan's age is just vaguely "mid-teens" from the looks of it (like Brock, his game counterpart seems to be an adult but the anime aged him down).
** Jessie and James. The only certainty is they're older than any of Ash's tagalongs. Jessie once said she was seventeen but that's probably her trying to seem younger than she is, and flashbacks imply she finished high school. The Japanese version has implied they're twenty-five in one of the movies and according to ''Radio/PokemonTheBirthOfMewtwo'' RadioDrama Jessie is over twenty. The radio drama supports Jessie being in her mid-twenties as the first part takes place twenty years before the series and Miyamoto (Jessie's mom) states her daughter is starting school.
** Cynthia is an adult but she doesn't look that much older than her late 20's. In the ''Anime/PokemonIChooseYou'' universe [[spoiler:she has a 10 year old daughter]] but doesn't look that old. She either [[spoiler:had Verity young ([[TeenPregnancy maybe even in her teens]])]] or she's a few years older than she looks.
* Mitsumi from ''Manga/PokemonDiamondAndPearlAdventure'' seems to be a teenager but her exact age is never given. She seems older than Jun, but he in turn seems [[AgeLift older]] than his game counterpart so that doesn't help much.
* Jasmine is clearly in her late teens to early twenties in the ''VideoGame/PokemonGoldAndSilver''. In ''Manga/PokemonAdventures'' she is the same size as the preteen Silver when she first appears.
* ''Franchise/SailorMoon'':
** Applied to Luna the cat in ''Series/PrettyGuardianSailorMoon'', who despite sounding identical to the version in ''Anime/SailorMoon'' (who was a VagueAge full grown cat until she briefly became a [[HumanAliens human(oid)]]), was given the body of a very young girl as a occasional human form. She was described by mangaka Creator/NaokoTakeuchi as being a year younger than the lead character and became a teenaged girl when human, but also has been alive since the Silver Millennium.
** Usagi's younger brother's age can fluctuate from between two and four years younger than her depending on whether you're watching TheNineties anime, the live-action series, or reading [[Manga/SailorMoon the manga]].
* Amae Koromo from ''Manga/{{Saki}}''. Though she appears very child-like, she is a second-year student as opposed to the majority of Kiyosumi High's players like Saki, Nodoka, and Yuuki who are first-years, and it's been hinted that she's older than Nodoka.
* With the exception of three characters- Maka, Kilik, and Black*Star who are all confirmed to be 13 years old in the first half of the series- none of the cast in ''Manga/SoulEater'' are given specific ages. This is not helped by the fact that the DWMA doesn't sort its students out by age, but instead by when the student enrolled and what skill level they are at. Tsubaki and Liz are hinted to be at least 2-3 years older than them, while it's unclear if resident Shinigami Death the Kid is either OlderThanHeLooks or ages just like them. When it comes to the adult cast, given that Spirit had Maka when he was 18, it can assumed that they are around their 30s. If the character is either a Witch or related to magic, they're even harder to pin down given that they can live for centuries.
* Sunrise has been rather opaque about the ages of the heroes in ''Anime/TigerAndBunny''. So far, they've only given out two and a half: Barnaby's 24, Kaede's 9, and Kotetsu's kinda sorta probably somewhere between 33 and 39. [[ShrugOfGod Maybe]].
* ''Manga/YuGiOh'':
** As stated in the current page quote, it's never clearly stated how old [[FillerVillain Noah]], Kaiba's stepbrother is. But if we were to make a guess, then he looked about twelve when Gozaburo showed him the photo of Kaiba, who was about seven at that time. So it can be guessed that Noah is five years older than Kaiba and would have been twenty-one had he been alive.
** Shizuka's age is also a myth. She looks about the same age as Anzu, but is definitely younger. Her age is guessed to be either fourteen or fifteen.
** Mana's age is never stated clearly by Takahashi either. The anime made her younger than Atem for about 2 years, but then she is too big-breasted for a mere fourteen-year-old, so she can probably also be a case of OlderThanTheyLook and is actually older than Atem. We can't be sure, though.

[[folder:Comic Books]]
* ''ComicBook/{{Asterix}}'': Asterix himself is described as being "older than he looks." Between the art style used for all the characters, and the features of Asterix himself, he looks somewhere between 20 and 60. What that actually makes him is anyone's guess. Lampshaded in ''The Cauldron'', where he's working for a wrestling promoter who actually describes him in his 'roll-up' pitch as being 'of indeterminate age'. (One short story strip of dubious canoninity - due to being outside of an official volume and containing some inconsistencies with other stories – states Asterix and Obelix are 35 "when their adventures begin".)
* WesternAnimation/DonaldDuck:
** Donald Duck's nephews, Huey, Dewey, and Louie in Carl Barks' comics. In one story they are in kindergarten; in another they are shown driving a car! (The "kindergarten" they are attending is a rather unusual one, however; in the background of the first panel, there appears to be an [[EEqualsMCHammer integral equation written on the blackboard]].)
** Also Donald Duck himself. It's obvious that he is not really young or old, but it's not clear (and it [[DependingOnTheWriter depends on the writer]]) if he's still somewhat young like in his late twenties or he is middle-aged.
* Franklin Richards, the child of ''ComicBook/FantasticFour'' members Mr. Fantastic and the Invisible Woman, is somewhere between four and ten. Whether his [[RealityWarper reality warp]] power cause the age vagueness or if the age vagueness ''causes'' the reality warping is up for debate. It's actually a RunningGag that his age is never stated It has also been suggested that he is the source of [[ComicBookTime whatever effect it is]] that has kept the Fantastic Four's [[SuperHeroOrigin maiden flight]] [[SlidingTimescale "about ten years ago" for the last thirty years or so]].
* ''ComicBook/GastonLagaffe'': Lagaffe is old enough to smoke and have a car, a job, and his own place, but young enough to constantly play around at work and bawl his eyes out over very little.
* ''ComicBook/SpirouAndFantasio'': Spirou spent the 1950s stuck in a limbo where he looked like a teenager (being [[OneHeadTaller one head shorter]] than his adult friend Fantasio), but drove a car and had his own apartment. He finally became unambiguously adult shortly before or after Creator/AndreFranquin left the series.
* ComicBook/JimmyOlsen, Franchise/{{Superman}}'s Pal, would go back and forth between being old enough to drive, have a pilot's license and drink, and still being in high school, touching on every stage of life in between at least once. Lampshaded in one issue where a [[ActuallyADoombot childhood-obsessed, adult hating]] [[DependingOnTheWriter version]] of the Toyman tells his [[MultipleChoicePast story]] to Jimmy Olsen alone because he doesn't trust anyone over the age of eighteen. Jimmy kicks him over and shouts that he's ''twenty-three'' years old exactly.
* ''ComicBook/{{Tintin}}'': It's never made exactly clear how old Tintin is. He is obviously young, but has no problems going round the world and getting into adventures without any mention of parents or the like. It is known that he works as a reporter, but he's not seen actually performing this job. He does live together with Captain Haddock in his castle, along with Professor Calculus. In response to this, Herge was actually asked to create a character with a family, mum, dad, little sister, pet, etc. in order to have a more "realistic" series of adventures. The result was ''ComicBook/JoZetteAndJocko'', a fun, but less successful series. As Herge pointed out, it was much harder to keep track of all those characters. At least good old Tintin was unencumbered. Not everyone gets to be an orphan.
* ''ComicBook/ScottPilgrim'' [[LampshadedTrope lampshaded]] this all the time with Ramona Flowers. While every other character would have their age blatantly stated every time they were introduced (especially [[MemeticMutation Knives Chau, Age 17]]), Ramona's introduction was always followed by "Age Unknown." At one point, Scott ''lampshades the lampshading'' when Ramona gets mad at him for not knowing how old she is. He defends himself with, "But your age is unknown!"
* Granted, TheSmurfs are defined as 100 years old, but what makes them an example of the trope is the fact that it's unclear which human age equals that; most of them have specific jobs inside the village, yet they frequently play ball and act immature. Maybe one thing or the other may be the consequence of living in a small village led by their father (Papa Smurf is no mere name -- he raised the 98 Smurfs). They were more clearly defined as adults when three of them were age-reversed to Smurflings, which made the adult Smurfs behave somewhat more mature. This gets even more complicated with the appearance of Gutsy Smurf with his [[HotbloodedSideburns sideburns]] in the [[Film/TheSmurfs live-action movie]], since most of his fellow Smurfs don't have facial hair.
* Unlike other versions of the series, ''ComicBook/SonicTheComic'' never stated the age of anyone. Their ages were either never stated at all. The series goes by its own canon, so it's possible that most characters maybe don't fit their game ages. Tails looks the around the same age as he normally is (eight to ten). Amy however never really did seem to be as young as she was in ''VideoGame/SonicCD'' (which was eight) and in general seems more like a teenager. Sonic and Knuckles can visit bars so they're probably adults.
* Comicbook/DoctorStrange started out somewhere in his fifties, though the standard depiction is of a man somewhere in his mid-forties. Even so, the only real indication of his greater age are some lines on his face and the {{Skunk Stripe}}s of greying hair at his temples.
* The pygmies in ''ComicBook/PocketGod'' may appear to be small children given their size, but most of them don't act like it. They don't even know their own ages or how long they've been around; probably as a side effect of their ResurrectiveImmortality.
* Thanks to her HealingFactor being forcibly activated at the age of ''seven'', ComicBook/{{X 23}}'s age becomes much less clear. She ''looks'' about 17, but because her aging process is slowed by her mutation, [[OlderThanTheyLook she can easily be years older than this]]. However a closer look at the dates given in her various solo appearances does confirm an age of 17 by the time she joins the X-books proper: She escaped the Facility at 13, was 14-15 while staying with her cousin and aunt (which can be verified because Megan was still in high school, and is known to be a couple years older than Laura), and 15-16 during ''NYX''.
* Kitty Pryde is the original example of this in ComicBook/XMen comics. Introduced the TagalongKid of the team, she slowly appeared to age up. This came to a head when Creator/WarrenEllis took the reigns of ''ComicBook/{{Excalibur}}'' and decided he wanted Kitty to be in a relationship with the very much adult Peter Wisdom. This sent the Marvel Offices into a panic because in their minds, Kitty was still a "teenager". Eventually, they found middle ground and decided to [[MayDecemberRomance portray the romance]] as being like "[[Franchise/StarWars Leia and Han Solo]]." Since then, writers have been extremely vague with exactly how old Kitty actually is, especially considering there's been other characters who were introduced as teenagers after Kitty up rapidly aged up to be the same age as her or even older.
* Franchise/{{Batman}}'s butler, Alfred Pennyworth is typical older than Bruce Wayne, but it's not really clear how old he's supposed to be, and adaptations can wildy vary in his age. Promotional materials for ''WesternAnimation/TheBatman'' painted his age at around his early 50s, yet if Sean Pertwee's age is anything to go by, the Alfred in ''Series/{{Gotham}}'' is around that when Thomas and Martha Wayne died. Creator/MichaelCaine was 71 during the fimling of ''Film/BatmanBegins'', which features a Bruce Wayne who's 30 and just starting out as Batman, whereas Creator/JeremyIrons was 65 for the filming of ''Film/BatmanVSupermanDawnOfJustice'', which features a Bruce Wayne in his 40s with a 20 year career as the Dark Knight.
* Comicbook/SquirrelGirl was 14 years old when she was first introduced in 1992, but [[ComicbookTime since it's nearly impossible to measure the passage of time in the Marvel Universe]], subsequent writers couldn't seem to agree on how old she should be. ''Comicbook/NewAvengers'' hinted at a past sexual relationship with {{Wolverine}}, implying that she was an adult and probably in her 20's, while ''Comicbook/TheUnbeatableSquirrelGirl'' has her as a college freshman, which would indicate she's around 18.
* In Fawcett's [[ComicBook/{{Shazam}} Captain Marvel]] stories, [[http://worldsmightiestfamily.tumblr.com/post/141778044334/from-the-fawcett-companion-the-best-of-fca the official guidelines for writers]] say that while [[KidHero Billy Batson]] is fourteen (twelve when the series started), his age should never be stated so that kids can relate to him no matter how old they are.

[[folder:Comic Strips]]
* In ''ComicStrip/LittleNemo'', Flip's age is perennial a mystery, referred to at different points as a child and 23, and the same height as Nemo with a receding hairline and cigar.

[[folder:Eastern Animation]]
* In ''Animation/QumiQumi'', Juga, Yusi, and Shumadan are obviously young, though their personalities can range from being eight-year old children to eighteen-year old teens in various episodes.
* Leafie from ''Animation/LeafieAHenIntoTheWild'' is an adult but exactly what age she is when she leaves the factory farm is unknown. This is muddled further by the English dub, where she has a rather young sounding voice. [[spoiler:Leafie ages quickly over the film but it seems to be more from malnutrition and poor living conditions than her aging]].

[[folder:Fan Works]]
* Most of the main cast of ''FanFic/TheBunker'', In some episodes the gang is shown driving, In some episodes ACF appears in, she looks like a Powerpuff Girl.
* In ''Fanfic/TheParselmouthOfGryffindor'', Professor Max has been the Ghoul Studies professor "since the 18th or 19th century", and calls 120-year-old Dumbledore "young"… but at the same time does not look that old, not having a single gray hair for one thing. Methuselah Syndrome is probably at play.
* The Agents in ''FanFic/AkatsukiKittenPhoenixCorporationOverhaul'' are implied to be somewhere between mature teenagers and in their twenties. This is muddled by the fact that they don't live in a linear timeline, and some of them simply look older in a relative manner to the others. For instance, Agent Diamond is less than five feet tall (despite her impressive bosom), and is a bit of a PsychopathicManchild, while her boyfriend, Agent Chimera, is six foot three and generally quite mature. All but one of the Agents are stated to have been born within two years of each other.
* Averted in the ''Fanfic/EmpathTheLuckiestSmurf'' series, as Empath and his fellow Smurfs are depicted as being in their early adult stage around 150 years of age, with Homnibus commenting on how young Empath looks for his age.
* In ''Webcomic/KillLaKillAU'', there's this with Ragyo and Soichiro, which would be hard to figure out, as they (then) have three kids who were eleven, nine, and eight and both Ragyo and Soichiro's parents are shown to have grey hair when they're first seen, along with being married for at least seven years prior to their divorce, thus at the most they would probably be in their late thirties at the least, if not early forties at the most. In that vein, there's also Rei, the drunk secretary, although, apparently, she is old enough to drink and can be seen doing so [[labelnote:Note]]To go a bit further, the legal drinking age in Japan is at least 19 or 20 years old, something the authoress didn't know at the time of the comic's start[[/labelnote]]. What makes Soichiro's age more vague are his siblings, considering that his oldest brother, Bunmei, looks to be a good 11 or 10 years old, at the time he was shown as a baby [[http://kill-la-kill-au.tumblr.com/image/144558466643]], which in turn brings his parents' age into question.
* From the [[Fanfic/Gensokyo20XX Gensokyo 20XX series]], there's this with the kids but more explicitly with Yume Ni, An, Maribel, Renko, and an age-regressed Reimu. What is known so far is Yume Ni and An are fairly close in age, with Yu being at least a toddler at the time of An's birth and Reimu being at least in her formative years age-regression wise, with Maribel and Renko being a little unable to say their names correctly, as well speaking more on the level Reimu spoke at. The best estimate for the kids in general would be that their ages are vague, although Reimu and Chen would be older than they are chronologically, as biologically the former's a child, where as chronologically, she would at least in her twenties, and Chen is a youkai definition of a child, as far as that goes. From a branch off, ''Foundling'', Reimu again is supposed to be a toddler or, as the narration seemed to suggest, as she is shown to be past walking age, yet she is described as not being old enough to articulate (or rather, converse).
* There's this with a ''Anime/KillLaKill fic'', titled ''[[https://www.fanfiction.net/s/11037352/1/%E9%A3%9B%E9%B3%A5-Asuka Asuka]]'', particularly when the titular "Asuka" (who is implied to be either Ryuuko or Satsuki, never made clear which) [[spoiler: dies of her illness]]. She is described as being "so young" when she was diagnosed and presumably didn't make it to her teens, according to her sister's narration.

* ''Fanfic/KiryuuinChronicles'' has Satsuki, Ryuuko, and Nui's ages. Their ages are not mentioned, however, Satsuki is stated is to have been too young to comprehend what was going on between her parents and then later her mother's mental illness, as her recollections of the past support, and she states that Ryuuko and Nui were too young to understand death and neither were they old enough to remember the events leading up to the house being burned down and them fleeing from it.
** Similarly, this occurs ''[[http://archiveofourown.org/works/4407929/chapters/10011842 Train Tracks]]'', with Rei, Satsuki, Ryuuko, and Nui's ages, although, Rei's implied to be a teenager, at least to Satsuki's understanding. Semi justified as Satsuki doesn't quite remember how old they were at the time she narrated.
* Due to her mother's treatment in ''FanFic/CellarSecrets'', [[spoiler: Ryuuko's]] age is a hard to gauge, as her growth and subsequent development was stunted, however, it was mentioned that she's younger that Nui but how much younger isn't known. To elaborate further, Nui is 16 and Satsuki is 20 [[labelnote:Tidbit]]This was a case of WritersCannotDoMath, as the authoress miscalculated 17.5 +2.5 and thought it added up to twenty-one, when it was actually 20. She had since corrected this mistake.[[/labelnote]],by the time chapter 12 comes around. Ryuuko's vague age is a plot point, as her age not being known complicates rehabilitation, as the older she is, the less they are to recover what was lost to isolation (i.e, see [[https://en.wikipedia.org/wiki/Genie_(feral_child) Genie]]). What definitely forestalls calculation is the fact that when her sisters find scant photos of Ryuuko, they have the month and date on them but they don't have a year on them, in which case they go by her appearance in the photos, along with the fact that the two that did know, Ragyo and Rei, her secretary, are dead and there are no real legal documents of her.
* In the ''Fanfic/TwiceUponAnAge'' series, this is the case with Mahanon. The [[VideoGame/DragonAgeInquisition Lord Inquisitor]] doesn't actually know how old he is, because - as he explains to Varric, who mentions it in a letter - the Dalish don't pay much attention to things like birthdays. He knows that it's been about fifteen winters since he received his facial tattoos, which he received as a young man, so they estimate him to be in approximately his early thirties.
* Like the above Anime example, Ash Ketchum in ''Fanfic/PokemonResetBloodlines'' has an uncertain age. In the old timeline at least. Yes, even ''Ash himself'' doesn't know how old he was in the original anime, and in reference to it he can only measure things in gyms (That happened over the course of five gyms, it took four gyms for X to evolve, etc). Even looking at his memories, [[spoiler: Sabrina]] can't figure out how old he exactly was, and even notes that at one point May seemed to have aged ''backwards''. In the new timeline Ash is well aware of his age, which is 15, and wondering what his canon age was is a running gag.

[[folder:Films -- Animation]]
* Jack Skellington from ''WesternAnimation/TheNightmareBeforeChristmas'' is adult-sized and, in personality and voice, he comes across as being in his late twenties or early thirties. But then again, [[DemBones he's an undead skeleton]], and supposedly the [[PhysicalGod embodiment of Halloween]]… so for all we know, he may be centuries old and just ''seems'' youthful.
* Fidget from ''Disney/TheGreatMouseDetective'' is also a tough one. Olivia refers to him as "old", but he is small, somewhat cute and has a high-pitched voice; in one of the spin-off comics, post-Heel–Face Turn, he was implied to be a teenager just a handful of years older than Olivia, if you can believe that.
* The video game characters in ''Disney/WreckItRalph''. While all game characters are technically immortal unless they die along with their game or outside of it, Ralph looks to be in his 30s while Felix and Calhoun appear more in their late 20s. Meanwhile, Vanellope and all her racing rivals are supposed to be about 9 or 10 years old. The games they come from (and by extension, the characters themselves) have different ages. Ralph and Felix have been around for 30 years. Vanellope's game has been around for at least 15 years and Calhoun's game was only installed a week before the events of the movie, making her the youngest character chronologically.
* ''WesternAnimation/MyLittlePonyEquestriaGirls'':
** The series seems to hint that the Humane Five are 17, and this is Twilight's age when she goes to the human world. However, many child characters are age-lifted to be freshmen as well. To make it even more complicated, Sunset Shimmer (confirmed in the comics to be older than Twilight by a fair margin) seems to be the same age when they become human.
** [[AllThereInTheManual A piece of side literature]] called ''[[http://mlp.wikia.com/wiki/Wondercolts_Forever:_The_Diary_of_Celestia_and_Luna Wondercolts Forever: The Diary of Celestia and Luna]]'' portrays Celestia as a high school senior during Luna's freshman year, indicating that human Celestia is three years older than human Luna.
* ''Disney/TheLionKingIISimbasPride'':
** Kovu and Kiara can be anything from the equivalent of teenagers to being young adults. Their designs, voices, and the fact the film is based on ''Theatre/RomeoAndJuliet'' implies the former.
** Vitani is not Kovu's litter mate but doesn't look much older than him. Due to Kovu being implied to be adopted, it's possible for them to actually be the same age.
* The two TokenHuman characters in the ''Anime/AnimalCrossing'' movie look and act like children but live alone amongst adult FunnyAnimal characters and drink coffee. In the games the protagonist is heavily implied to be an adult however [[ArtisticAge the style makes them look younger]].
* Scamp from ''Disney/LadyAndTheTrampIIScampsAdventure'' looks like a young puppy but has the voice of a teenager. His sisters sound younger despite being his littermates.
* The titular Peter from ''Disney/PeterPan'' has all his baby teeth (which usually begin to fall out at age five or six) according to the original book, but his design resembles more of a boy between ten and thirteen.
* The younger contestants in ''WesternAnimation/{{Sing}}'' are the most ambiguous when it comes to their age. None of them are seen attending school, which exists due to Rosita's kids going there. Ash is referred to as a "teenager" but she seems to live alone and looking for work with her boyfriend [[spoiler: until they broke up]]. Johnny lives with his father but has the voice and body of an adult and when his father goes to prison, there is no mention of child services or social work. Meena lives her family and they treat her like a younger teenager but [[spoiler: her singing ability proves to far surpass this alleged age.]]
* In the educational animated film duology ''[[WesternAnimation/MuzzyInGondoland Muzzy]]'', this is played straight for everyone except Bob. The ages of the other characters is anyone's guess, but Bob explicitly states he is 20 when he is asked his age.

[[folder:Films -- Live-Action]]
* ''Film/IndianaJonesAndTheLastCrusade''. Alison Doody was 22 when the movie was filmed, and while Dr. Elsa Schneider has no onscreen age, she has to be at least thirty.
* ''Film/ETTheExtraTerrestrial''. According to the novelization of the film he's over 10 million years old. Other sources put him at about 800 years old, and he's shown to be a child in the [[ExpandedUniverse book E.T: The Book of the Green Planet.]]
* Four and Eric in the ''Film/{{Divergent}}'' films. [[Literature/{{Divergent}} The book states]] that the initiates take their test when they're sixteen, and Four and Eric's generation are eighteen. In the films they are played by actors in their late twenties, so their ages are left deliberately vague as a result.
* Creator/MichellePfeiffer as Selina Kyle/Catwoman in ''Film/BatmanReturns'' is a curious bit of casting. Pfeiffer was 33 years old when filming began, but her character often acts as if she's just out of college. Indeed, Selina comes across more as a stereotypical Gen-X StepfordSnarker than the assertive Baby Boomer career-woman type who was so common in American films of the 1980s and early '90s. Perhaps Pfeiffer (born 1958) [[TropeMaker helped originate the trope]]?
* ''Film/{{The Wizard Of Oz}}'' never makes it quite clear if Dorothy is supposed to be a child, as she blatantly is in the original book, or an adolescent. Judy Garland was sixteen at the time, but [[SuppressedMammaries costumed to look younger]], and promotional materials tend to give the character's age as twelve. A retrospective released for the film's 75th anniversary noted that Judy was told to remember that "she was a little girl from Kansas."
* ''Film/TheDisasterArtist'': Lampshaded in regards to Tommy Wisseau, who claims to be about the same age as Greg, who is 19, yet is clearly pushing 40. He refuses repeated efforts to pry his age from him, as well as a variety of other personal details he keeps mysterious. This is based on the real behavior of Wisseau, whose true age is still not publicly known.

* In ''Literature/ABrothersPrice'', the ages of the younger princesses are left vague, but they are not "of age" and still play with toy soldiers. Due to them being RoyalsWhoActuallyDoSomething, this is not as good a hint on their actual age as it could be - they could deliberately continue to play war with their younger sisters in order to learn about strategy and line of command. There also are some older noblewomen mentioned in the backstory, who are "ancient", but there's still no word about their actual age, they could simply have aged badly.
* Vardaman from William Faulkner's ''Literature/AsILayDying'' has no set age, and it is often debated as to whether he is young or just retarded (or both). He's the youngest of his five siblings, and the next-youngest is obviously at least a teenager.
* ''Literature/ASeriesOfUnfortunateEvents'':
** Sunny is [[WiseBeyondTheirYears exceptionally clever for a baby]], and her physical development occurs in a deliberately uneven, contradictory way; for example, even after [[spoiler:she learns to walk]], she is small enough to sleep in a casserole dish. Her exact age is not specified for the first twelve books, and flashbacks to "before Sunny" carefully avoid giving her older siblings' ages at the time, forestalling calculation. The thirteenth book stated that Sunny was about two, which would mean she was about six months at the most in book one, and eighteen months have passed since.
** Carmelita Spats. In the book where she is introduced, she seems old enough to be the leader of a GirlPosse and to be one of the most popular girls in school -- but, in the later books, she acts much younger.
* Everyone in ''Literature/TheMoomins'', though some are more vague than others, and especially Snufkin.
* It was initially unclear how old ''Literature/HarryPotter'''s parents were when they died. While their friend Sirius (who is the same age) is referred to as "young Sirius Black" in the first book, his friendship with the Potters isn't revealed until the third book, and the "young" could easily be taken as EarlyInstallmentWeirdness. In a 2001 interview, however, it was indirectly confirmed that they did indeed die young--less than four years after graduating (the interview in question was about Snape's age). However, the first movie, which was released the same year, contradicted this to make them appear middle-aged, and until the final book, their age at the time of their deaths was something you'd have to be pretty observant to know.
* Ascanius, Aeneas's son in the ''Aeneid'', is at varying points in the poem young enough to curl up on Dido's lap at dinner (or at least, no one thinks it's weird when Cupid impersonates him to do so), and old enough to fight in the war. He appears to be somewhere between four and fourteen, never specified.
* Creator/DianaWynneJones deliberately kept the ages of her child-characters vague unless there was a plot reason not to, to broaden their appeal to child readers. At a certain stage it can be off-putting to find out that the hero of the book you're reading is younger than you are (if you're eleven, nine seems pretty young). In ''Literature/{{Hexwood}}'', some characters' VagueAge is a plot point in itself.
* Applegate used this trope in ''Literature/{{Animorphs}}'' to make the titular group relatable to as wide a demographic as possible. In-universe, this was justified as part of the characters' many attempts to protect their own identities. In the last book, it was revealed that they were 13 at the time they first met Elfangor and 16 by the time the Yeerks surrendered.
* Literature/TheBible:
** In the Literature/BookOfGenesis, the story of Isaac's near-sacrifice has him speaking to his father Abraham the way a young child would, asking him, on the way up the mountain, where the sheep was for their burnt offering, and Abraham replying evasively, "God will see to the sheep for his burnt offering, my son," as though to shield him from the horrible truth until the last moment. However, based on the internal chronology of the book, Isaac would've been thirty-seven years old at the time. Thus, the Jewish sages of late antiquity [[ExploitedTrope exploited]] this ambiguity, portraying Isaac as old enough to give informed consent to his own sacrifice.
** Another Genesis example of this trope is Benjamin, youngest son of Jacob, at the time of his family's relocation to Egypt. His birth takes place before his older brother Joseph is sold into slavery, which should make him at least twenty-two at the time of their Egypt reunion. Yet throughout that later part of the story, his father and brothers still refer to him as a "lad," shelter him and barter over him as if he were a child. And yet the subsequent list of Jacob's sons, grandsons and great-grandsons who traveled to Egypt includes the names of Benjamin's many children. It seems likely that two different versions of the story with different chronologies were combined.
** The ages of Jesus' disciples are never explicitly mentioned in the Bible. They are usually depicted as adult men of assorted ages.
* Chichi deliberately invokes this in ''Literature/AkataWitch''. She refuses to tell anyone how old she is, except when she's teasing an older man. After she gets him excited, she tells him she's twelve (or whatever age she feels like being), laughs at his horror, and runs off.
* L. Frank Baum's ''Literature/LandOfOz'' books:
** Apart from her being a "little girl," Dorothy's age is never made clear. The original illustrations for ''Literature/TheWonderfulWizardOfOz'' portrayed her as only about five or six, but later illustrators have sometimes made her look as old as twelve. ''The Giant Horse of Oz'' eventually implies that she's eleven, though this takes place several years after her first visit to Oz. And of course, due to AdaptationDisplacement, the general public tends to imagine her as [[Film/TheWizardOfOz sixteen-year-old Judy Garland.]]
** Ozma's age is never concrete either. Some illustrations have her as an adult while some have her as a child. Typically she's depicted as being Dorothy's age; however, it's also stated that she's an immortal fairy. Well, sometimes - Baum was very inconsistent with Ozma's backstory.
* In the ''Literature/RainbowMagic'' series, it's never stated how old Rachel and Kirsty are supposed to be. They could be anywhere from very young to middle school aged.
* Professor Cole in ''Literature/{{Murderess}}'', who can transform into a teenage boy and back.
* Literature/{{Coraline}} is hard to pin down. Illustrations make her seem anywhere from 11 to 14 and she's stated several times to be small for her age so she could easily be a teen. Mentally she can be similar to a middle schooler but at other times seems more like an 8 year old. The [[WesternAnimation/{{Coraline}} film]] pins her age at 11.
* In ''Literature/DragonBones'', this is something of a plot point. Axiel's exact age is not known, and [[spoiler: he is later revealed to be half dwarf, and much older than he looks]]. While ages are given for younger characters, this is often not the case with the older generation. Aunt Stala, for example, might be a CoolOldLady, as her hair is already grey, but she is the half-sister of Ward's mother, who gave birth to him when she was about sixteen, and therefore could be about thirty-six. Though of course Stala could be a lot older than her sister, being illegitimate.
* ''Lterature/TheAdventuresOfTomSawyer'': Tom Sawyer is an oft-cited example of this trope. He's described as "a small boy" and sometimes shows the naiveté of a very young child, yet his romantic interest in Becky Thatcher and bouts of melancholy brooding feel more suited to a twelve- or thirteen-year-old.
* Varjak from ''Literature/VarjakPaw'' is repeatedly referred to as a kitten but already looks like an adult cat (albeit smaller). Due to how cats age, it's unknown if this means he's a preadolescent or a teenager. Cats are considered kittens until they are one years old and six-month olds can be almost as large as their parents.
* In ''Literature/TheSorcererOfTheWildeeps'', Captain's age is never specified and he gives off conflicting cues depending on the audience. It is unlikely that he's ReallySevenHundredYearsOld, but Demane mentions that Captain's been in the mercenary business for a couple decades already. His looks are very vague, age-wise, and his behaviour is that of a hardened veteran towards the band and that of an occasionally insecure 20-something when alone with Demane.
* Aging the characters in ''Literature/WarriorCats'' can be difficult. Cats are considered kittens until they're 12 months old, but in ''Warriors'' cats stop being kits at 6 moons. However, instead of being adults, they're treated more like mature teenagers and are noted to still be growing.
* The title character of ''Literature/PeterPan''. He still has all his baby teeth, which would imply that his physical age is just five or six, but his intelligence level seems higher than that (of course he is Really700YearsOld) and all the female characters have crushes on him. Ditto for Wendy, who is said to be the same size as Peter, but whose maturity level is far past the "still has only baby teeth" phase. Unsurprisingly, most adaptations ignore the baby teeth issue and make both Peter and Wendy seem about twelve years old.

[[folder:Live-Action TV]]
* ''Series/ThirtyRock'': Kenneth appears a bit too old to be in the age bracket likely to work as a network intern, but there's also quite a bit of evidence that he might actually be [[OlderThanTheyLook older than he appears]]. No definitive answer has ever been given. Seriously, just check out the OlderThanTheyLook section on the series' main page. If he's to be believed, Kenneth has been working for NBC since '''''[[spoiler:1936]]'''''.
* ''Series/{{Community}}'': Abed is somewhere in his twenties, but where is anyone's guess. Several episode imply he's actually in his mid-thirties (matching his actor) and thus much closer to Shirley and Jeff than he acts.
* ''Series/{{Merlin}}'': Has never given any definitive ages for its cast, though WordOfGod has it that of the four leads, Morgana is the oldest, followed by Arthur, with Merlin and Guinevere clocking in as late teenagers when the show begins. When taking into account the [[TimeSkip Time Skips]] that occur between seasons, nearly ten years have passed in-show, meaning that the cast (all in their mid-twenties when filming began) went from DawsonCasting to PlayingGertrude.
* ''Series/TheBigBangTheory'': Most of the characters are in their twenties, nobody knows where. Subverted with Howard, who is said to be 26.
* ''Series/{{Revolution}}'': The characters have not been given ages for the most part. However, Danny Matheson is supposedly 19 years. This is reasonably close the character's actor Creator/GrahamRogers's age, which is 17 years old. Captain Riley is apparently the youngest captain the Monroe Republic has. The actor playing the character Creator/OmidAbtahi is 34 years old.
** Danny Matherson said he was 18. Neville barely knew Danny, but said he was possibly 19. It may be better to believe Danny.
* ''Series/{{Smallville}}'':
** Lex Luthor has the ability to somehow blend in with high school students.
** Clark himself probably helped. The character of Clark Kent was 15 at the start of the series or close to it, judging by his grade in school, [[DawsonCasting but his actor was 25 at the time]].
* ''Series/TheSuiteLifeOfZackAndCody'':
** In the first season, Zack and Cody are presumably the same age as their actors: 12 or 13, while Maddie and London are in their late teens. However, in later seasons (and in the spinoff), they are clearly older teens, while Maddie and London are the same age: In the spinoff the twins and London go to school together.
** When Zack and Cody graduate in the spinoff, their actors are about 18/19 years old. [[AsianAirhead London]] graduates at the same time, despite originally being a few grades ahead of them, because she kept flunking grades.
* ''Series/TheVampireDiaries'': All of the Originals' ages are unknown. Rebekah and Kol are teenagers, where in their teens they fall is anyone's guess and Klaus, Elijah, and Finn are total mystery. It's also unknown at what age Katherine was turned.
* In the seasons of ''Series/PowerRangers'' where the characters are not high school students, the Rangers' ages tend to be left vague at best. They are often provided in promotional materials (for some characters), though even these are notoriously unreliable: Bridge, the only character in ''Series/PowerRangersSPD'' with a definitive age, was listed as 17 on the Jetix website but is explicitly 21 in the show proper.
* ''Series/{{FarScape}}'', for much of its run, which is odd considering how often the show mentions time passing. In the first episode, D'Argo's age is given as 30 cycles (young for a Luxan, which means he married very young -- a plot point). Everyone else's age stays mostly vague. Chiana is often stated to be "a kid" compared to the others, and acts as though she's in her late teens/early twenties. John's age can eventually be inferred as about 30 when he joins Moya, since he's old enough to drive in 1986 and was presumably born in 1969 or 1970.
* In ''Series/TrueBlood'', only the vampire characters ever have exact/approximate ages given, usually for dramatic effect like Russell being over 3,000 years old or Jessica being 16 when turned in Season 1. The humans' ages are kept vague, not helped by the show's rather fluid sense of time. Lampshaded by Nicole's mother when she objects to her relationship with Sam:
-->"You are 23 years old! And may I ask how old ''you'' are, silver fox?!" (This becomes her "nickname" for him.)
* ''Series/{{The 100}}'' has an InUniverse example: WordOfGod is that Grounders don't keep track of birthdays, so their ages can only be given a rough estimate. Most notable with Lexa, the Grounder's Commander. She's young enough that Abby refers to the Grounders as being "led by a child", but it's unclear if that's literal and Lexa really is under 18, or if she's simply unusually young given that she's leading an entire nation.
* ''Series/TheGoldenGirls'' has Blanche Devereaux, who prides herself on her looks and as such constantly lies about her age, usually implying herself to be in her early forties or even her late ''thirties''. The other girls of the house however are not fooled despite her overconfident facade, and several jokes have been poked at how they can't pinpoint her exact age. In one episode Rose manages to acquire her birth certificate from her home state of Georgia, only to find her age "[[NoodleIncident Deleted By Authority of the Governor]]". Adding to this, the season two opener sees Blanche coping with menopause, suggesting she is indeed well into her fifties. All hints aside though, Blanche usually succeeded in keeping herself relatively youthful looking for a woman her age.
* ''Series/TheNanny'' has Fran Fine, who is constantly dodging questions regarding her true age, even though in season one she celebrated what was allegedly her thirtieth birthday. Many in the household though have wondered if she's actually older, with her always coming back to insist that she could still be in her twenties.

[[folder: Music]]
* Music/MelanieMartinez:
** The protagonist of the "Cry Baby" ConceptAlbum. She's played by 20-year old Melanie in music videos but the actual character is vague in age. In the "Pity Party" music video there are nine candles on her birthday cake (though fans do argue if it's symbolic of something else) and artwork depicts her as a little girl. She also dresses in stereotypically "childish" attire such as pastel dresses with ribbons, but that's a popular fashion for adults as well. The overall lyrics and tone of her songs makes her sound like someone in her late teens or early twenties. It could be a bad case of TroublingUnchildlikeBehavior.
** Whether DawsonCasting occurs in her music videos is vague, and if so in ''which'' videos. In "Pity Party" Melanie can be either an adult or a child. In "Training Wheels" whether she is a child or not is made vaguer by fact the other adult dresses in boyish clothes. In the video to "Cry Baby" Melanie could [[AlternateCharacterInterpretation either]] be an adult playing a toddler or Cry Baby could have an AbusiveMom who makes her dress like a baby.
* The Jamster/JAMBA [[Music/{{Schnuffel}} bunny characters Schnuffel and Schnuffelienchen]] (Snuggle and Snuggelina) both appear to be young bunnies but both live on there own without any parents. Doesn't help that they both have cute high pitch voices (Except in the audio [=CDs=] released in Germany where Snuggle and Snuggelina are voiced by actual adults).

[[folder:Puppet Shows]]
* ''Franchise/TheMuppets'': Most of them, since they tend to have abstract appearances anyway. For ''Series/SesameStreet'' characters, this is done for psychological appeal; the regulars are supposed to emulate different stages of childhood development, and each character's 'official' age is just a reflection of that.
** Though ''Film/TheMuppetsTakeManhattan'' shows the main cast graduating from college.

* Musicals in general tend to have a case of this. Unless it is plot relevant, a character's age will probably be vague enough to allow actors spanning a decade to play them. Possibly more.
* Theatre/{{Hamlet}}. He's a university student, he was passed over as heir when his father died, and the play is more or less his ComingOfAgeStory, all of which would seem to put him in his late teens. But the scene with the gravediggers gives his age as thirty (or thereabouts), and he remembers Yorick, who died twenty-three years prior. The historical explanation is that Hamlet was probably originally intended to be a teenager but that Shakespeare changed his age so his [[ProductionPosse usual star]] Richard Burbage could play the role.
* In Music/GiacomoPuccini's ''Theatre/GianniSchicchi'', the DramatisPersonae lists almost every character with his or her age, omitting the usual VoiceTypes. Buoso's poor cousin Betto di Signa, however, is specifically designated "età indefinibile" (of indeterminate age).

* How old is Franchise/{{Barbie}}? Originally she seemed to be a high schooler. However Mattel has aged her up over time. Currently she is portrayed as a young adult while her sister Skipper is a teenager. Still, Barbie has [[ImprobableAge become US president]] and done other things that imply she's older than her twenties. ''WebAnimation/BarbieLifeInTheDreamhouse'' affectionately pokes fun at, and lampshades, her VagueAge.
* The characters of ''Toys/MilkyWayAndTheGalaxyGirls'' are [[AnthropomorphicPersonification human versions of planets]] so it's likely they don't [[Really700YearsOld age like humans]]. Still, their physical ages are highly ambiguous. They just look... [[ArtisticAge young]]. They could be anywhere from teenagers to being in their twenties.

[[folder:Video Games]]
* ''VideoGame/MapleStory'' allows your character to marry ([[BribingYourWayToVictory For NX, of course]],) even if they look like they're not even close to maturity. Some of the quest givers give off the impression of being young (i.e. a student attending a magic school), but appear to be just as tall as your character and don't have a clear age either. In one quest line, you begin by playing hide and seek with children. A few levels later, you're fighting in a revolution.
* It says something that Link's age alone in ''Franchise/TheLegendOfZelda'' has spanned a large FlameWar among fans:
** Early in his series, Link's age was indeterminate, and his sprite had too little detail to tell. In-manual art drew him like Peter Pan with more hair, making it more unclear how old he actually was. The exception is in ''VideoGame/ZeldaIITheAdventureOfLink'', where he is explicitly 16 years old (he's also the Link from the first game a few years later). Most of the later console games give him a more explicit age, but the handheld games are still vague. It wasn't until much later when Link in ''VideoGame/TheLegendOfZeldaI'' was confirmed to be 12 years old from the same source that stated that ''Ocarina of Time'' Link was 9 years old as a child (however the original Link has also been referred to as 10). Link in ''VideoGame/TheLegendOfZeldaALinkToThePast'' may be implied to be a prepubescent kid, not only by the AV Famicom commercial (which oddly promotes the cartridge port of ''VideoGame/TheLegendOfZeldaI''), but also by the GBA port of the game, where he is given young N64 Link's voice. His design, however, is more reminiscent of a teen in his early teens according to official art.
** In ''VideoGame/TheLegendOfZeldaTheWindWaker'' Link's age is never mentioned in the game itself, but while [[AllThereInTheManual the official strategy guide]] pins him at twelve, the game itself states that Link starts his quest at the same age as Link from ''VideoGame/TheLegendOfZeldaOcarinaOfTime'' (9 as a child, 16 as an adult). The games that follow ''The Wind Waker'', namely ''VideoGame/TheLegendOfZeldaPhantomHourglass'' and ''VideoGame/TheLegendOfZeldaSpiritTracks'', both made Link look rather young because of his chibi model.
** His age isn't stated, but is generally assumed to be between 9 and 16 in ''VideoGame/TheLegendOfZeldaMajorasMask'', as he is younger than the 16-year-old model but it is stated to have been a while since the events of ''Ocarina of Time'', at the end of which he stayed 9.
** ''VideoGame/TheLegendOfZeldaTwilightPrincess'' supplemental material confirms his age there as 17. He's the same age in ''VideoGame/TheLegendOfZeldaSkywardSword'', though Miyamoto had suggested during development that he would be even older.
** Link's age in ''Ocarina of Time'' is even this. Official sources have called young Link both 9 and 12. This would make his adult form either 16 or 18. The ''Ocarina of Time'' Link Toys/{{amiibo}} says he is 17. The in-game debug refers to young Link as ''5'' while his adult version is 17, which isn't accurate to the game as that's a 12-year difference (implying in development the timeskip was larger).
** Zelda herself is an oddity. Her age is never given but she rarely, if ever, seems too different in age than Link. ''Twilight Princess'' Zelda is the lone exception - supplemental material confirms her to be 20. This has not stopped fans from debating her age, however.
** Link and Zelda traditionally look the same age but Link in ''VideoGame/TheLegendOfZeldaALinkBetweenWorlds'' and Zelda seem to have an age gap. Zelda looks like she's in her teens but the PuniPlush style could be at fault. Link looks and sounds like he's under 13 but his official art muddles his age by making him look like a teenager. The fact that [[spoiler:their darker counterpart's Hilda and Ravio seem more similarly aged despite Ravio sharing a slightly modified version of Link's model]] makes things even vaguer.
** Link in ''VideoGame/TheLegendOfZeldaBreathOfTheWild'' is vague due to his androgynous looks and his babyface. He is described as not yet an adult, and he is too young to drink alcohol, but is also stated to at least be seventeen as he was able to climb Mount Lanayru, which in-universe is barred to anyone under seventeen. Not helping matters is the fact that that pod Link wakes up in? [[spoiler: He was asleep in it for 100 years to recover from near fatal wounds]]. Link can bring this up at a bar, but no one believes it, leading to the above.
* ''Franchise/SuperMarioBros'':
** Princess Peach. In the games (especially in her 3D appearances) she has a decidedly mature physique and is even taller than Luigi; however, in the western comics she acts more like a tomboyish tween, and her relationship with Mario seems to be one of childish infatuation, with the "''WesternAnimation/TheAdventuresOfSuperMarioBros3'' [[UniverseBible Writers Bible]]" calling her a seventeen-year-old (albeit this was never mentioned in the series proper and seems to have been made up by Creator/DiCEntertainment). Her original design in her first appearance resembled a child, so that is probably the cause of the discrepancy, and she was likely aged up for the second game to be a closer match to Mario as a result. Also, in ''VideoGame/PaperMarioTheThousandYearDoor'', the Shadow Queen refers to her as a "child" (though the Shadow Queen is a 1000 year old demon and could be using "child" metaphorically).
** This also applies to Mario, Luigi and Bowser. ''VideoGame/MarioAndLuigiPartnersInTime'' shows the three, plus Peach, as infants; yet in their adult years, Peach hasn't lost her youthful look. The Mario brothers are implied to still be in their twenties, and they're just a bit older than her.
** Mario was confirmed as approximately 26 in his Japanese trophy description for ''VideoGame/SuperSmashBros Melee'', and Miyamoto confirmed in 2016 that he is about 24 or 25; either way, he is estimated to be in his mid-twenties. Luigi is his twin brother (but born after him) so he is the same age. Peach and Bowser still remain a mystery, but since Peach couldn't even walk as an infant in ''Partners in Time'' and Bowser could talk as an infant, which the baby Mario Bros. can and can't do, respectively, Peach is implied to be a year or so younger and Bowser a year or so older.
** Yoshi. The official voice was introduced in ''VideoGame/YoshisStory'' for a group of Yoshi infants, yet in later games, the same voice is used for its grown form. In ''VideoGame/PaperMarioTheThousandYearDoor'', it gets even weirder as the Yoshi there apparently hatches out of the egg with vague knowledge of the world ("Is that one of those 'kiss' things? I've go to get me one of those!") and no name, but talks like a teenage punk and generally acts like an adult.
** Kamek. He's presumably pretty old given how he was an adult back in the ''VideoGame/YoshisIsland'' series (and is still around now), but how old? Who knows, he hasn't even changed design in the 20 odd year time skip. Only thing that ever changed for him was the colour of his robe and wizard hat (and by one shade of a blue at that). There is, however, the possibility that he is a LegacyCharacter, as he's pretty interchangeable with his Magikoopa kind (even sharing the same name in Japanese materials, which tend to not distinguish between alike individuals of a given species).
** Rosalina. She looks to be in her 20's or ''maybe'' early thirties, but visits the Mushroom Kingdom ''every 100 years''. She is implied to be immortal, but that doesn't explain why she physically appears younger in the optional flashback story.
* The questionable art skills of ''VideoGame/{{Touhou}}'''s creator ZUN have made the intended age of most characters unfathomable from their official portraits. Since WordOfGod stays extremely vague on the subject, this has left the fandom free rein on their age. Even more than the others, [[{{Catgirl}} Orin]] and [[CuteWitch Patchouli]] (who wears baggy clothes) have fallen victims to this trope, alternating between cute girls and fully grown women, DependingOnTheArtist. Even limiting it to the humans, whose ages presumably matter more, it's extremely unclear how old Marisa and Reimu are supposed to be, with the range often being given as things like 10-20. And even if their precise age is given at one point, it's unclear if they're aging or not. If each change of the seasons indicates a year passing in-story, they'd be somewhere in their 20s by now. A [[JustifiedTrope justified]] example comes from [[NinjaMaid Sakuya]], who has TimeMaster powers. Though she's been described in-game as looking to be in her late teens or early twenties, she displays skills and knowledge far beyond someone of that age, and her boss Remilia has said that Sakuya's been serving her so long that it's hard to think of her as a human being anymore. Since one game shows her demonstrating the ability to accelerate an object's aging (making a bamboo flower bloom instantly rather than the 60 years it normally takes), it's generally assumed that she has the corresponding ability to ''de''celerate aging as well, which would explain her appearance perfectly.
* Amareus of ''VideoGame/YggdraUnion'' is one of only a handful of characters in the game whose age is not explicitly stated somewhere or other. Instead, the official website gives the viewer a ballpark-estimate quote: She's "2? years old".
* Flora in ''Franchise/ProfessorLayton''. The only clue given for Flora's age is that the events of the first game happened after she was "out of childhood," but she's still young enough to require a guardian; most players estimate her to be between fourteen and seventeen.
* Many in ''Franchise/{{Pokemon}}'', especially the protagonists:
** For a very long while, the only protagonist with a confirmed age was [[VideoGame/PokemonRedAndBlue Red]], who's 11 in the first games [[AllThereInTheManual according to the manual]] and presumably their remakes, presumably 14 in ''VideoGame/PokemonGoldAndSilver'', ''Crystal'', and their remakes, at the very least 16-17 by the time of his reappearance in ''VideoGame/PokemonBlackAndWhite2'', and has been stated to be in his early twenties in ''VideoGame/PokemonSunAndMoon'' by WordOfGod, making him anywhere from 20 to 24 in these games. According to the same manual, [[TheRival Blue]] is the same age as Red, and [[DistaffCounterpart Leaf]] can be presumed to be the same age as well. [[VideoGame/PokemonColosseum Wes]] is stated to be around seventeen to eighteen, and Lucy Fleetfoot from ''VideoGame/PokemonTrozei'' is said to be just a bit older than him.
** The ''VideoGame/PokemonBlackAndWhite'' protagonists are stated to be older than previous heroes of the main series, but it's unknown by how many years.[[note]]WordOfGod is that they were visualized to be sixteen[[/note]] The sequel protagonists are even worse, looking younger than Hilda and Hilbert but older than characters like Red or May.
** Many people assume the player characters are around 10 thanks in part to the anime making Ash 10, but again, the only protagonists in the games with outright stated ages are a year older than that. Also, Michael is identified as "an unknown teen" in ''VideoGame/PokemonXDGaleOfDarkness'', so he could be at least 13, yet he looks about the same as the characters from the main games (not to mention he's about a head shorter).
** The ''VideoGame/PokemonXAndY'' protags muddy these waters even further; thanks to the VirtualPaperDoll feature of the games, their clothing and hairstyles can make them ''look'' older or younger. On one extreme, "cute" outfits can make them look like the ten-year-olds everyone associates with Ash and Misty (Serena even getting some Misty-like outfit options), while on the other end of the scale, outfits from Snowbelle or Lumiose can make them look like early college students. Even more confusing is that your character has to bend down to talk to young children, but not ''all'' children. A character, [[spoiler:Emma]], who is roughly the protagonists' height is identified as being sixteen, and said character is OlderThanTheyLook. The protagonist is implied to be older than them as well.
** ''[[VideoGame/PokemonRubyAndSapphire Pokémon Omega Ruby and Alpha Sapphire]]'' averts this with many characters, as the news you see on the [=PokéNav=] confirms ages for several characters (for example Wally is 10 and Professor Birch is 35). The protagonists' age is still mysteriously absent despite the news discussing them quite often. However, due to the unselected player character being indicated as 12, the player can be presumed to be 12 as well.
** There is also a set of protagonists with a confirmed age, and in-game at that; the unnamed protagonists of ''VideoGame/PokemonSunAndMoon'', who are 11, just like Red was at the start of his journey. This is confirmed by Wicke asking you at one point if you are "around eleven", with both dialogue options basically amounting to "yes".
** The ''Pokemon'' games never keep track of the ages of individual Pokemon, making it impossible to tell how old it is. Evolution is also not an indication of age, as they can evolve whenever the correct trigger is hit, and can easily prevent it from occuring. The closest thing to aging is that Baby Pokemon are incapable of breeding unless they evolve into a higher form and even that means little because only a select few Pokemon are considered "Baby Pokemon".
* Terra, Aqua and Ven of ''VideoGame/KingdomHeartsBirthBySleep'' are never given official ages, unlike Sora, Riku and Kairi. Though if you take some things into consideration, such as Ventus being physically identical to Roxas (Nobody of fifteen year old Sora) and WordOfGod telling fans that [[spoiler: Xemnas is about thirty]], it's not that much of a stretch to assume that Ven is about fifteen and Terra is about nineteen. It IS told that Aqua is younger than Terra and older than Ven.
* Maxwell from ''VideoGame/{{Scribblenauts}}'' is never given an age, though ''Scribblenauts Unlimited'' establishes he's still a kid.
* ''VideoGame/AnimalCrossing'':
** Your fellow villagers in are... mystifying, to say the least. They live on their own, so they're adults, right? But some of them mention still having allowance, and some of their birthday messages imply they're not yet adults. But there are no parents anywhere (and, in fact, the female kangaroo villagers ''have children of their own''). The "Grumpy" and "Snooty" villagers act older than the others, with some of their dialogue implying they're probably at the youngest, in their early 30's. With the rest of the clan, it's anybody's guess. It gets even more confusing with the bear villagers as there are both full grown bears and cubs ''and they're treated as different species''.
** The protagonists are equally vague. You look like children but are implied to be adults (they live on their own, pay mortgages, and drink coffee), thouh at least one letter implies you're not an adult yet. ''New Leaf'' made the player characters [[NoodlePeople more lanky]] and less SuperDeformed, but they still resemble children in some aspects (while also making them mayors of the town). ''Series/SuperSmashBros 4'' makes it even vaguer as they refer to Villager as a "young man" in his trophy. He doesn't have a voice so you can't tell his tone either.
** It's hard to tell how old Sable is. She appears to be of similar age to the (apparently) middle aged Tom Nook but doesn't seem that old. There is an age gap between her and Mabel, as Sable was PromotedToParent as a youth, but the gap doesn't seem too large. Sable is vaguely anywhere from her early thirties to somewhere in her forties.
* ''VideoGame/GoldenSunTheLostAge'':
** Made a plot point with Piers. After visiting his homeland, where [[ReallySevenHundredYearsOld people age extremely slowly]], the characters start asking Piers about his age. Piers refuses to answer, and gets upset when the others start pressing the issue. He worries on-screen that [[JustifiedTrope knowing his age would change how his new friends see him]] (and it's also possible he's just embarrassed about it). Fans consequently tend to assume he's [[OlderThanTheyLook significantly older]] [[IntergenerationalFriendship than the rest of the cast]], possibly bar [[CoolOldGuy Kraden]].
** None of the Proxians have stated ages, but Karst gets this the most due to being noticeably shorter than the others (though still about as tall as Felix) and having [[CuteMonsterGirl more humanlike features]]. In-universe, the only thing that is said about her age is that she's younger than Menardi. Fans have estimated her to be anywhere between 15 and 30. And that's assuming that they age at the same rate as normal humans, which also isn't clear.
* ''Franchise/SonicTheHedgehog'':
** Nobody knows how old the villainous Doctor Eggman is supposed to be. The only clue about his age is that he was alive when his grandfather died fifty years ago.
** Despite the characters all looking a couple of years older in the spinoff series ''VideoGame/SonicBoom'', they are still the same ages as their main series counterparts.
** Sega seems to have settled on 8 years old as Tails' canon age, but historically he's been all over the map, from as young as "four-and-a-half" to as old as 12, depending on the game/media. This generally seemed to coincide with whenever Tails [[TheOtherDarrin got a new voice actor]] (typically because the old one was played by a boy whose voice changed).
** Sonic's age in the classic games. Documents pin him as anything from 16 to 18. ''Adventures'' solidified him as 15. ''Generations'' brought back the confusion with a {{retcon}} implying that the classic games were Sonic's past adventures. Tha brings to question Sonic and Tails' ages.
* Characters from ''VideoGame/ParappaTheRapper''. For an example, Parappa himself is old enough to drive a car and join the military but not old enough to work.
* Franchise/{{Kirby}} was described in the [[AllThereInTheManual manual]] of ''VideoGame/KirbysDreamLand'' to be a "little boy" but gave no age, and his age in games since then hasn't really been touched upon.
* Some of the characters in the ''VideoGame/WarioWare'' series fall into this. Ashley's the most obvious example (her 'official' age is supposedly around 15 according to the US website, and unstated in Japan), and her design is so vague that it's kind of hard to tell what age the character is outside of 'looks fairly young'. Same deal with 18-Volt, who looks like anything between a high school student and adult, who's somehow still in elementary school, in the same class as the much younger-looking 9-Volt.
* ''VideoGame/DontStarve'': Willow. [[PsychopathicManchild Psychopathic Womanchild]], or EnfantTerrible? The art style makes it hard to tell how old she is, though WordOfGod says that she's the same age as Wilson, who's at least old enough to grow a beard.
* The cast of ''VideoGame/HarvestMoon'' games tend to be this:
** One of the few games where all of the characters have defined ages is the "Forget-Me-Not Valley" series of games (''[[VideoGame/HarvestMoonAWonderfulLife A(nother) Wonderful Life]], [[VideoGame/HarvestMoonDS DS (Cute)]]''), where [[AllThereInTheManual the manual]] gives the characters' ages. This can be especially confusing given that there are certain characters who state that they're older than the protagonist, [[MayDecemberRomance especially when they're romanced]], but who look exactly the same as everyone else due to [[PuniPlush the cutesy art style.]] A prime example is Muffy, who is in her early thirties but looks as young as the twenty-somethings. Celia and Nami look like they're in their early twenties as well, and Celia is so youthful that it's even noted in-universe that [[OlderThanTheyLook she ages well]].
** Luna in ''VideoGame/HarvestMoonTreeOfTranquility'' is so short she resembles the other children on the island, but is of marriageable age. This naturally caused a bit of {{Squick}}, so in ''VideoGame/HarvestMoonAnimalParade'', she got a height boost. She's still on the younger side, especially in [[ElegantGothicLolita the way she dresses]], but how ''much'' so still isn't clear.
** Calvin from ''VideoGame/HarvestMoonTreeOfTranquility'' and ''VideoGame/HarvestMoonAnimalParade'' is an especially confusing case. When romanced, he alludes to there being an [[MayDecemberRomance age difference]] between him and the protagonist. However, his character profile explicitly refers to him as a ''young'' man. Either the protagonist is really, really young, or she's [[OlderThanTheyLook older than she looks.]]
** Soseki from ''VideoGame/HarvestMoonANewBeginning'' is another odd case. He also alludes to being decently older than the protagonist. However, most of the other SilverFox bachelors in the series had AnimationAnatomyAging to indicate them being older--Soseki doesn't. This leads to the common fan theory that he's not that old at all, but he's ''extremely'' self-conscious about it. [[{{Hypochondria}} It wouldn't be out of character.]]
** Ann from ''VideoGame/HarvestMoon64'' and other future games looks like a teenager but can be married.
** All of the bachelorettes from ''Harvest Moon 64'' count. The [[AllThereInTheManual Japanese Famitsu strategy guide]] to the game gives everyone's ages ''but'' the bachelorettes and the protagonist.
** Nina from ''VideoGame/HarvestMoon1'' looks absurdly young in the official art and has a [[ManChild more]] [[GenkiGirl childish]] persona than even the neighborhood kids, but apparently is an adult. ''VideoGame/HarvestMoonMagicalMelody'' remedies this by making her look like someone who is at least eighteen, despite the chibi art style, and the English translation removing her use of her name as a pronoun.
** This is averted with ''VideoGame/HarvestMoonSaveTheHomeland''. All the major characters have known ages. For example, Toy (the protagonist) is twenty-one while the OlderThanTheyLook Katie is sixteen.
** ''VideoGame/HarvestMoonIslandOfHappiness'' has Pierre. He outright looks like a ten year but is apparently of marriage age.
** Both Fritz and Mistel from ''VideoGame/StoryOfSeasons'' look quite young but can still be married and aren't treated like kids.
* In ''VideoGame/EndlessOcean: Blue World'', nobody's age is pinned down, but of note are Professor Sakurai, who is said by Oceana to be "too young" to have done all she's done; Oceana herself, who, at least in the NA version, has to be at least 15 since her father's accident is stated to have been 15 years ago, and is more likely to be 17 or so, as she was "very young" at the time rather than "not born" or "just a baby"; and the player character, who joins the diving service while taking a break from courses.
* Usually this isn't an issue with main characters in the ''VideoGame/TalesSeries'', but Judas's age is a problem. [[spoiler: Leon was 16 when he died]], and Judas still looks young, but [[spoiler: considering he was revived at some undetermined point between the Eye of Atamoni incident and the present]] in ''VideoGame/TalesOfDestiny2'', and he's treated like the old guy of the group, he could be anywhere from 16 to 34.
* ''Franchise/SpyroTheDragon'': Spyro is a KidHero but his age is never specified. According to ''VideoGame/SpyroYearOfTheDragon'', dragon eggs hatch once every twelve years, so he could be twelve.
* The [=CPUs=] in ''Franchise/{{Neptunia}}'' are immortal goddesses, throwing any relevance of their exact age [[OlderThanTheyLook out the window]] to start with, but there's still the question of how old [[UsefulNotes/NintendoDS Rom and Ram]] are intended to be. On one hand, they look about 10-12, can go out on Lowee's streets unsupervised, and have basic reading ability fitting that age. On the other, Rom still prefers to have picture books read to her and can't walk to the bathroom alone at night, and Ram boasts about being above such things.
* ''VideoGame/FireEmblem'':
** The [[KidFromTheFuture time travelling future children]] in ''VideoGame/FireEmblemAwakening'' are never specified to be any particular age, other than "looking almost the same age as their parents" (due to TimeTravel). We know Lucina is slightly older than most of the other children, as supports confirm she was born before them, and Laurent is physically 3 years older than her due to a time travel accident sending him back further into the past than the others, but other than that, nothing. This is actually necessary for gameplay though, as it's possible for the kids' fathers to fall victim to FinalDeath, meaning exactly when the mothers would have to get pregnant could be anytime, so it had to be left as vague as possible.
** ''Franchise/FireEmblem'' runs on this trope in general. The main protagonists will usually be given a specific age; for example, Lyn, Eliwood, and Hector from ''[[VideoGame/FireEmblemElibe Blazing Sword]]'' are 16-18. Apart from that, though, all bets are off. You can get some clues from support conversations, but hardly anyone else has their age directly stated.
** The [[HalfHumanHybrid Branded]] from ''Path of Radiance'' and ''Radiant Dawn'' age much slower than normal Beorcs (humans). Thus, they can be much OlderThanTheyLook. The Laguz from the same game also have incredibly long life spans, making some of them centuries old at the least.
*** Soren realized he was aging slower than usual, and looks a bit short. [[spoiler: He's half-dragon and half-human. Another dragon character, Ena, took years to have a child. Her [[WhereAreTheyNowEpilogue ending]] states she gave birth even though her fiance died 3 years ago, and the last time she could have had sex with him was [[LongestPregnancyEver 19 years before that]]. Yet, since Soren's mother was pregnant by a Beorc, she may or may not have had a shorter pregnancy, making him 19 at the oldest, which fits when his uncle left Goldoa to help them.]]
*** Micaiah looks like a teenager but is also old enough to have looked after Sothe as he grew up, but young enough to be [[spoiler: Sanaki's sister. It is established that Micaiah was born prior to the Serenes Massacre, which gives her a minimum age of 23, while her inability to remember her origins gives her a maximum age of 27.]]
*** Kaze (and his twin brother Saizo) of ''VideoGame/FireEmblem Fates'' is old enough to have been deployed as a guard when the Avatar/Corrin was kidnapped, but young enough to have been "a child" when it happened. The kidnapping itself was "over a decade ago" according to Azura, making a lot of the Nohrian and Hoshidan nobles' ages hard to figure out, even the Avatar themselves.
* The ''VideoGame/JumpStart'' franchise zig-zags this trope. Token humans Polly Sparks and Jo Hammet are clearly a third grader and a fifth grader respectively. The original incarnations of Mr. Hopsalot and Frankie were obviously an adult rabbit and an adult dog. On the flip side, the FunnyAnimals in the 2001-2004 games play this trope straight. They all appear childlike, and this incarnation of Hopsalot mentions in Advanced 2nd Grade that finding clues "gives [him] an excuse to stay up past [his] bedtime". However, no parents are seen or even mentioned and they all seem really self-sufficient. The 1990s version of Jump Start Preschool also plays this trope straight; the featured FunnyAnimals speak in childlike voices, but Casey Cat wears a necktie, so it is difficult to tell whether they are supposed to be the students or the teachers.
* As per Nintendo norms, no one in ''VideoGame/{{Splatoon}}'' is given an exact age. The closest we get are the fact Inklings can only become perfectly humanoid [[PubertySuperpower at roughly fourteen]], so that's the minimum age for the main character, Judd is [[spoiler:thousands of years old, being from the age of humans]], and Capt'n Cuttlefish is implied to be over 100 years old. Everyone else is up in the air:
** Callie and Marie look older than the playable inklings but aren't specified (it isn't even stated if they're the same age or not), though it's implied they're old enough to drive. Considering they're idols, it's unlikely that they're older than their mid twenties.
** Off the Hook are the only characters in the entire series to have confirmed ages: Pearl is [[OlderThanTheyLook 21]] and Marina is 18. Prior to that, it was anyone's guess what age Pearl was. She has a BrattyHalfPint personality and a very childish look but is an inkling and is treated adult.
* Almost nothing is known about the Fairytale Detective, the hero of the ''VideoGame/DarkParables'', except that she's a woman. However, one bit of information allows for an educated estimate of her age. Thus far, the only attempt at a timeline for the series is confirmation that the third game takes place ten years before the seventh; it can be approximated, therefore, that the series has been happening for at least roughly fifteen years in-universe, which would put the detective at the time of the tenth game in at least her thirties. She could possibly even be older than that, depending on how old she was intended to be when the series began, but since she was already established as a professional detective in the first game she must have been an adult.
* Tiny Kong from the ''Franchise/DonkeyKong'' franchise is Dixie's younger sister. Tiny hit a growth spurt and now seems to be a teenager, but Dixie is still treated like a KidHero. She should be an adult, but there hasn't been any sign of either her or her boyfriend Diddy aging. It's possible Tiny is [[YoungerThanTheyLook in her early teens]] or ''VideoGame/{{Donkey Kong 64}}'' Tiny was OlderThanTheyLook.
* ''VideoGame/SubwaySurfers'' has a soft, PuniPlush style and features the characters illegally jumping around dangerous train tracks [[ShouldntWeBeInSchoolRightNow in the middle of the day]]. It's hard to tell what age several characters are. They all sort of look like tweens, though some like Lucy and Tasha are designed a bit older looking and several female characters dress in [[BareYourMidriff midriff showing]] outfits.
* Many characters from ''VideoGame/{{Undertale}}'':
** The protagonist is never given an age but is explicitly referred to as a child and their sprite [[PintSizedKid makes them look quite small]]. This could mean they're anywhere between five and twelve years old.
** Papyrus collects action figures, believes in Santa, wears an armor costume, sleeps in a racecar bed and is [[CloudCuckoolander rather loud and eccentric]]. Yet he is very tall, has a job, is old enough to join the Royal Guard and keeps Sans in line [[spoiler: and is elected as ruler of The Underground [[MultipleEndings depending on who's available]]]]. Many fans just assume he's a teenager or a manchild. This is even [[LampshadeHanging lampshaded]] by Monster Kid if you talk to him after fighting Papyrus:
-->'''Monster Kid:''' I wonder if that weird skeleton is an adult or a kid.
** Muffet is described by her creator as "a lil' baby spider monster", but she looks to be way older than infancy, runs her own bake sale, and addresses the game's protagonist as "deary", a term of affection more often used towards younger people. This description was evidently meant to be figurative in reference to her cute design and not literal, so Muffet's real age is anyone's guess.
** Monsters' ages in general are hard to pinpoint. While [[spoiler: Toriel and Asgore]] [[TheAgeless do not age]], it is unclear if/how [[OurMonstersAreWeird monsters age and mature in accordance with humans]]. Many of them do act naive and childish, however.
*** The characters' ages may be hinted at by their handles on [=UnderNet=]. [[DemBones Papyrus]], [[FishPerson Undyne]] and [[OurGhostsAreDifferent Napstablook]]'s usernames are [=CoolSkeleton95=], [=StrongFish91=] and [=NAPSTABLOOK22=] respectively. If this is refering to their birthyear, that will place Papyrus around 15-24, Undyne around 19-28 and Napstablook 88-97 years old depending on what time of the year they were born and when the game takes place. The Fallen child arrives in the underground in the year [[YearX 201X]] [[spoiler: and the game takes place during an unspecified time period afterwards[[note]]The year Frisk arrives in is referred to 201'''x''', not 201'''X''', implying that it's a different year, but within the same decade[[/note]]]].
* In ''VideoGame/TheElderScrollsVSkyrim'', all children share the same basic character model, regardless of age or maturity, which can fluctuate greatly between them. The only indication of specific ages given are for the ReallySevenHundredYearsOld vampire Babette (who was turned as a child over three centuries prior), and Aventus Aretino, who is 10 or 11 years old, going by an in-game letter.
* The player in ''VideoGame/{{Minecraft}}''. Steve/Alex is clearly an adult, or else they wouldn't be left alone or have a goatee (Pre-Beta Steve only, often thought of as a smile). In fact, it's also hard to estimate both's age range as well, given that everything in the game is pixelated. However, Alex looks fairly young. Steve may be too, but then again, their faces are pixelated, along with the rest of their bodies, meaning they are very hard to tell.
* While Luke has his age confirmed in the series, there's no clear answer to how old Flora is in the ''Franchise/ProfessorLayton'' games. The first game, where she's introduced, offers the only clue; her late father left explicit instructions that an heir to his ImpossiblyCoolWealth was not to be sought until Flora was "out of childhood." All we know for sure is that she's older than Luke but still young enough to require a legal guardian. Most players estimate her to be between fourteen and seventeen.
* Ribbon Girl is 17 and Mechanica is 14. They are the only two ''VideoGame/{{ARMS}}'' characters with known ages.
* ''VideoGame/{{Cuphead}}'': Both Cuphead and Mugman look rather young and live with their mentor, the Elder Kettle. And while the plot is kicked off by gambling, it's hard to tell if they're actually legal gambling age, or not, because it's unlikely that a casino run by the Devil would even care about that. According to writer Evan Skolnick, [[https://twitter.com/EvanSkolnick/status/953431259161673728 Cuphead and Mugman are adolescents]],[[note]]In case you didn't know, an adolescent is a teen that has hit puberty; in other words, they are teens: not children, but not yet adults.[[/note]] though the exact age is still unknown. However, in a Twitter response to a fan, [[WordOfGod StudioMDHR]] [[https://twitter.com/studiomdhr/status/949297839594704896 describes both of them as "kidults"]].
* ''VideoGame/PuyoPuyo'':
** Some characters do not have canon ages, but Witch has been given two different canon ages (13 in Sun and 15 in ~n respectively) and yet her appearance in ''Madou Monogatari ARS'' would indicate she is much older, closer to 180. Her grandmother Wish's official age is 65, but seeing [[OlderThanTheyLook as she is much older than she looks]] and anti-aging magic is present in the series it's not implausible to think she could also be much older.
** Lemres and Ms. Accord from the ''Fever'' series both canonically use anti-aging magic to remain young and dialogue referring to their ages is deliberately vague as to what that age actually is, making it hard to ascertain their true ages. Lemres is described as a senior in school but it is also implied he and Accord are old friends, while Accord is a middle school teacher.
* ''VideoGame/NightTrap'': A lot of characters do not have canon ages, although actress Dana Plato was not yet 23 when she played SCAT member Kelly Medd, who is pretty old enough to investigate the Martins' winery estate, though the other members call her a kid in the intro for the cancelled Control-Vision version (which is added for the 25th Anniversary Edition). Though there are four other adult actresses playing the roles of teenage girls, the actor playing the "kid brother" Danny (Joshua Godard) kinda looks like an adolescent boy. This is lampshaded by [[WordOfGod Tyler Hogle]] of Screaming Villains in an [[https://www.youtube.com/watch?v=df2zptiviBo interview]], when he says that he doesn't know Danny's age, but that people can interpret one of the {{deleted|Scene}} GameOver scenes as "a 12- or 13-year-old getting [[ImpromptuTracheotomy a drill in his neck]]".

[[folder:Visual Novels]]
* ''VisualNovel/HigurashiWhenTheyCry'':
** Satoko and Rika are noticeably younger than the high school aged protagonists but how much younger is never quite stated. Satoko seems to have entered puberty but Rika hasn't yet. They both use elementary school bags as well. The closest given to an age confirmation is that Satoko is anywhere from 9 to 13 years old, and Rika is officially the same as Satoko.
** Keiichi, Satoshi, Rena, and the Sonozaki twins are all of high school age but their exact ages are unspecified. Mion, Shion, and Satoshi were already high schoolers a year ago and are one year older than Keiichi and Rena. Mion is also shown studying for college in one of the ''Matsuri'' arcs.

[[folder: Web Comics]]
* The characters in ''Webcomic/WhatTheFu'' are only defined as somewhere in their twenties, mostly because [[UnreliableNarrator Zac]] can't be bothered with details.
* In ''Webcomic/CityOfReality'', none of the main characters have defined ages -- this is deliberate on the part of the author so as not to trip himself up with potential romantic subplots. The cartoonish art style doesn't help matters. However, it is possible to extrapolate from their statements about graduating high school and the assumptions people on other worlds make about their youth, and they got a visual (though again not textual) age-up between chapters 5 and 6.
* Cucumber and his sister Almond of ''Webcomic/CucumberQuest'' are, in the author's own words, "A young kid and a slightly younger kid." It is known that Cucumber isn't 9, because that's how old his father thinks he is.
* ''Webcomic/{{Sinfest}}'' is pretty weird with this. Word Of God is that Slick is somewhere between 14 and his early twenties, and the other characters rarely (if ever) get their ages touched upon. It's especially weird considering that most of the main male characters look considerably younger than the women (who all look somewhere from their late teens to twenties). It's not helped by the fact that just about every character lives on their own.
* ''Webcomic/TheDragonDoctors'' has this as a deliberate, in-universe social issue due to the fact that society has access to a functioning FountainOfYouth.
* The author of ''Webcomic/SchlockMercenary'' has confessed that he has no idea how old General Tagon is, guessing that he's somewhere between 18 and 40 years older than his 49 year-old son.
* ''Webcomic/{{Nebula}}'': With a [[TheBlank complete lack of facial features]] (and the fact that they have [[TimeAbyss incredibly long lifespans]] and don't seem to age much), it's hard to say how old any of the main characters are in human terms at all, other than than that they're ''presumably'' adults.

[[folder:Web Original]]
* ''WebVideo/YuGiOhTheAbridgedSeries'' lampshade this in episode 53, Yugi even brings up on how old they're suppose to be.
* ''WebAnimation/HappyTreeFriends'': According to the creators, the Tree Friends are [[ArtisticAge whatever age is necessary for the cartoon to work]], aside from a handful of characters who are always portrayed as adults (though rarely competent).
* ''WebAnimation/HomestarRunner'' has only two or three confirmed "adult" regulars; the others can be, as the plot requires, young enough to be going to preschool or old enough to be drinking Cold Ones. Even the adult regulars aren't too old to play spaceman with tin foil outfits and cardboard spaceships. Don't even ask about Homsar. [[http://hrwiki.org/wiki/Ages_of_Characters This Page]] on [[TheWikiRule the wiki]] attempts to clear things up a bit. Emphasis on "a bit".
* The flash cartoon series ''WebAnimation/RetardedAnimalBabies'' has mocked this a few times. Despite the name "Babies" the character Bunny claims to have gone to high school and even had several wives (to which the character Puppy says, "Shit man, how old are you?").
* In ''Roleplay/DarwinsSoldiers'' this trope is made explicit by Ariol, Kain, Subject 19, Siren, Breathtaker and Stalker; all have their age listed in their profiles as "unknown".
* Most of the cast of Website/GaiaOnline qualifies, especially since the website ''does'' acknowledge the passing of years and the characters do have birthdays. They just don't resemble their alleged ages. At all.
* The Trapezoid Kids are deliberately drawn so that they need their TertiarySexualCharacteristics, exaggerated gestures, outer body colors, and voices for anyone to even ''tell them apart'', much less know exactly how old they are. [[TheBlank They aren't even drawn with visible faces]].
* The bikes in ''When Bikes Argue'' could be literally any age. But [[ArtisticAge only Betsy is described specifically as a child]]. The other bikes are allegedly between 20 and 50, in keeping with who might be riding them.
* Spoofed in ''WebAnimation/BarbieLifeInTheDreamhouse'', where ''nobody'' knows what Barbie's age is, not even her closest friends.
-->'''Teresa:''' She ran for President once! You have to be ''at least'' thirty-five for that, so let's see... CarryTheOne... uh... What am I adding?

* [[http://tokiandcowiki.wikidot.com/wiki:toki Toki]] and her twin sister [[http://tokiandcowiki.wikidot.com/wiki:doki Doki]] are older than they appear but how old they are is never stated, though, going by ''Doki's Chronicles'', they should be about either in their late eighties to early nineties, as the setting of one of the stories was in the nineteen twenties to thirties and their [[http://akaichounokoe.deviantart.com/art/What-Toki-normally-thinks-about-319433086 clothing]] from that point in time seems to suggest about that.
** There is also [[http://tokiandcowiki.wikidot.com/wiki:eglantine-rabbitwright Eglantine]] and presumably she is a toddler, as she is still in diapers and young enough to attend nursery school, though, if the passage of time is to go by, she should be four if not five and what is known is that she still a young child. Justified, in this case as no one has no clue as to how old Eglantine is because they don't know her birthday, thus they wouldn't know the year in which she was born in.
** [[http://tokiandcowiki.wikidot.com/wiki:brownie Brownie]]is stated to be "likely to be in early to mid twenties" though she was about twelve or thirteen when she met Toki, making that a tad more appropriate.
** [[http://tokiandcowiki.wikidot.com/wiki:magnolia-rabbitwright Magnolia]] is stated to be about 2-4
** There's [[http://akaichounokoe.deviantart.com/art/Killerbunnies-XI-and-XII-Kamu-and-Kanran-444451527 Kamu and Kanran]] who has a condition that makes them look like babies but they don't seem to let them stop them in being damn near malicious and that both are old enough to smoke but their ages are never stated. In that vein, it's hard to pinpoint how old Jeanne is or whether or not she is even a child or through some means or another just looks like one.
* Couette from ''Franchise/{{Noob}}''. She's [[TeensAreShort short]] and acts like a stereotypical teenage girl, but is also the DistaffCounterpart of the franchise ManChild undergoing DivergentCharacterEvolution. Her actress in the webseries is a short adult, but she also hints to still be going to class in some of her dialogue. The comic shows the other contestants at her beauty pageant to be much taller than her and that she lives in her own house, but has her drawn with the same standards as the ManChild in question, making look her like the youngest of all regular players.
* Cecil from ''Podcast/WelcomeToNightVale'', to go along with his [[TheVoice ambiguous appearance]] and [[AmbiguouslyHuman questionable status as a human]]. His childhood friend claimed to have been a teenager for decades at one point and when questioned [[spoiler: it is revealed that Cecil can't actually remember what year they graduated. And considering they both sound around the same age, that only raises more questions. Also despite having memories of growing up in Night Vale, a "Best Of" episode reveals that his first show recounted a group of settlers arriving at a barren wasteland and declaring that they will found a town there called Night Vale, and a later one has him excitedly telling listeners about a new technology called radio [[MindScrew that people will soon be able to listen to his show on]].]]
* ''WebAnimation/{{RWBY}}'':
** Cinder looks older than the high school aged cast yet at the same time is able to pass as a student by just wearing a school uniform.
** Neo is young enough looking to infiltrate the school as a high school student but other than that is very vague looking (no thanks to her short height and youthful design). The age gap between her and Roman is hard to distinguish; they could be years apart as easily as they could be the same age.
* Jeffy from ''WebVideo/SuperMarioLogan'' is obviously a highly unintelligent kid, but it is never stated just how old he is. Even he isn't sure of his age. In the episode, "[[BirthdayEpisode Jeffy's Birthday!]]", the only evidence of Jeffy's age is a half-torn piece of paper in his pants pocket, which has the day he was born (August 21) written on it, but not the year.
* In regards to the main characters of ''WebVideo/DontHugMeImScared'', the antagonists treat them like children, but the photos of them on their wall reads 19/06/55, which makes them quite old if home computers exist. The sixth episode shows a picture of Red Guy in a cap and gown with a diploma and implies that he works at an office, suggesting that he is at least a young adult.
* A majority of the characters in ''Toys/TheGrosseryGang'' webseries have ages that are hard to pinpoint, as they can hold down jobs, yet at the same time have squabbles that a child would. The only characters in an established age group are Stinky (the eldest as a senior citizen) and Egghead (the youngest, as the last to expire, and acts like a young child).

[[folder:Western Animation]]
* The ''WesternAnimation/{{Histeria}}'' Kid Chorus is stated to be in middle school (even the clearly teenage Toast and Pepper), but their exact ages are never stated (except for Froggo, who's ten).
* According to WordOfGod, the ages of the main characters of ''WesternAnimation/JimmyTwoShoes'' are purposely left vague in order to allow a bigger range of stories. [[EnfantTerrible Heloise]] looks like a little girl, but holds down a job as Misery Inc's top inventor, and all three live without parental supervision. Beezy can still get grounded and gets an allowance, but is old enough to [[ArrangedMarriage get married]].
* ''WesternAnimation/KimPossible'':
** Shego apparently has a degree in teaching but (when she's not committing crimes ForTheEvulz) acts like a teenager, lounging around the SupervillainLair reading fashion magazines. Her relationship with [[MadScientist Dr. Drakken]] (who is Kim's father's age) flipped between father-daughter and romantic, even though she had a one-episode romance with Senor Senior Junior, who is apparently young enough to crush on Kim and date her high-school rival [[AlphaBitch Bonnie]]. WordOfGod is that she was in her mid-20s by the end of the show.
** The ages of Kim and Ron (and by extension, their fellow students) are also never really addressed beyond WordOfGod describing them as "high school age". Although given a few details throughout the series (moving to senior year, being able to drive, graduating etc.) it can be reasonably assumed that they start out in the series at 14/15, before ending up at 17/18 in the final season.
* ''WesternAnimation/ClassicDisneyShorts'': WesternAnimation/MickeyMouse and friends. They're typically to be portrayed as adults, Goofy even has a son, but some merchandise and cartoons can easily portray them as students without changing much of anything. Of course even when they're portrayed as adults their ages are hard to pin down. Goofy is old enough to have the aforementioned college aged son and was shown to be an adult in 70s according to ''An Extremely Goofy Movie'' (which was a turn-of-the-century film), but Mickey and Donald seem much younger than that most of the time. Most of the time WesternAnimation/DonaldDuck is portrayed as an adult, however one short "Donald's Better Self" depicts him as a child.
* ''WesternAnimation/PhineasAndFerb'':
** The title characters, as well as their friends, were originally supposed to be nine years (as mentioned in the pilot), but when the creators saw how well various age groups responded to them they decided they were simply "less than fifteen" (in other words, younger than Candace). It's hard to get any clearer an example from how they act: Phineas is a CheerfulChild who's ObliviousToLove, while Ferb sounds like a teenager and has hints of being a CovertPervert.
** In "Quantum Boogaloo", they travel twenty years into the future, and future-Linda says that "her Phineas and Ferb" are thirty (which WordOfGod said not to take too literally). However, the DistantEpilogue episode "Act Your Age" is supposed to be set ten years in the future, and the two are just now heading for college.
* ''WesternAnimation/DaveyAndGoliath'': Davey, or any of the other characters, never have their ages mentioned. In the earlier 1960's episodes, Davey looked to be about 9-12, but in the 1970's series, he appeared to be around 12-14. We know he is younger than high school age, thanks to the episodes "The Stopped Clock", where Davey is a waterboy for the local high school's baseball team, and "Rickety-Rackety", where a boy who was failing french (The fact that they study french indicates that they are in middle school) says "Anyhow, my dad said he didn't have to take french until high school!" However, in "School, Who Needs It!" Davey and friends only have one teacher, suggesting they are in elementary school, but it is very possible they go to a K-8 school where each grade only has one teacher, judging by the fact their school is simply called Palmview School, not Palmview Elementary School or Palmview Middle/Junior High School. In the 1972 Davey and Goliath educational film "The Family of God", Davey takes his first communion, and the average age for Lutherans to start communing is fifth grade. However, it seems like a no-brainer for the Lutheran church to use popular children's characters that they owned in their first communion film, and the show was already running for 11 years when the episode was made, so this doesn't necessarily indicate the age of the characters. Furthermore, in the 1960's episode "Happy Landing", Davey's neighbor brings him to his job as a air traffic controller at a commercial airport. When the neighbor gets jokingly asked if Davey is a new pilot, he replies "Give Davey 12 more years and he will be up there flying in that plane." We don't know how old you needed to be to fly a commercial plane in the 60's, but if it was still 18 like it is now, that would suggest Davey was 6 in that series. However, if you need a Airline Transport Pilot license, you have to be 23, suggesting the more likely possibility that Davey was 11 in the 60's series.
* In his earliest cartoons, Porky Pig fluctuated between being a child and being an adult. The latter is easier to relate to, considering his future mild-mannered personality compared to the other ''WesternAnimation/LooneyTunes'' characters.
* The main characters of ''WesternAnimation/TinyToonAdventures'' are clearly young enough to be the offspring of the original Looney Tunes, to whom they are otherwise not related. Acme Looniversity has a prom as well as spring and summer breaks, and the Tiny Toons appear to be quite independent, but most of them still live with parents and are expected to obey their rules. These facts would normally suggest that they are high schoolers. However, the majority of the cast do not look like they are going through puberty. In fact, Montana Max and Elmyra Duff behave more like elementary schoolers, while only Fifi La Fume and Arnold the Pitbull resemble teenagers. Further confusing matters is the theme song's reference to getting a "degree" as well as the fact that "Looniversity" is a pun on "university".
* In ''WesternAnimation/TheRaccoons'', Bert acts like a child, but he also seemed to have graduated school and works as both a professional journalist and paperboy.
* Spike in ''WesternAnimation/TheTransformers'' - when he first appeared, he was working on an oil rig, but in a later episode, he mentioned he was too young for a driver's license. In the same episode, he ''begins a romance with a girl who is in college.''
* ''WesternAnimation/KaBlam'': Henry and June's ages are never stated in the show, but appearance wise, most likely nine to eleven, most fans put them at ten.
* The titular character of ''WesternAnimation/FlipTheFrog'' has a different age in different episodes. Sometimes he's portrayed as a kid, sometimes as an adult.
* The members of Dethklok on ''WesternAnimation/{{Metalocalypse}}'' are of a vague adult age. In the first season, Pickles is said to have run away from home 15 years ago at the age of 16, which makes him 31. However, he also played in a hair metal band in TheEighties. If he was, say, 19 in 1985, that makes him 40 when the series begins.
* Warner Brothers didn't want the writers to give Bruce Wayne an established age when he and Terry were celebrating his birthday in the ''WesternAnimation/BatmanBeyond'' episode "Out of the Past". They said in the commentary that he would have been around mid to late eighties.
* Who knows how old any of the penguins in ''WesternAnimation/ThePenguinsOfMadagascar'' are? It's worth noting that apparently Private is younger than the rest (but interestingly had at least one earlier identity as the Mini Golf champion Mr. Tux). We're given a clue that Skipper and company weren't alive, or at least were not yet adults, in the 1960s as Skipper wants to go back in time and slap a hippie. Skipper recalls an adventure where he woke up in a bed covered in Deutchmarks (the German currency that was discontinued by 2002). It's also worth noting that Buck Rockgut had been down in the tunnel under the zoo for forty-seven years when the penguins found him, and that it's implied that he's much older than they are. That's around twice a normal penguin's natural lifespan. TheMovie has a flashback to the time when Skipper, Rico, and Kowalski meet a newborn Private. The character designs of the very young penguins reflects the fact that they themselves were definitely not yet adults at the time and have not yet begun their adventuring. But then again, WordOfGod indicates that the movies are an AlternateContinuity.
* ''Franchise/ScoobyDoo'': The gang are old enough to travel on the road on a consistent basis but still young enough to be considered "Meddling Kids". This would suggest that they are very young twenty-somethings, but some episodes of the original series seem to treat them as high schoolers. WordOfGod has Velma (the youngest) at fourteen in the original series and the oldest two at eighteen. Some direct-to-video movies put them in their late twenties, but in ''WesternAnimation/ScoobyDooMysteryInc'' they are all explicitly still in high school, and while Shaggy's and Velma's exact ages are not specified, Daphne and Fred are both stated to be Seniors.
* Similarly, ''WesternAnimation/TheAmazingChanAndTheChanClan'' places the older kids in their teens and Flip in his preteens. Only the three youngest are given actual ages in canon.
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'':
** The main cast seem to show whatever level of maturity is required to make this episode's plot work. They all live independently and most work professionally, but also often act like teens (with things like slumber parties). Their interactions with explicitly pre-adolescent characters seems to vacillate between slightly older sibling to responsible adult figure. It's complicated even further by one minor who apparently has an explicit "teen as distinct from adult" stage. The only hard numbers that exist on ''any'' characters' ages are that Celestia, Luna, and Discord are well over a thousand years old, Sweetie Belle looked significantly younger during a flashback to when she was five years old, and Fluttershy is a year older than Pinkie.
** The mane cast's age was implied in one episode by showing Applejack as a baby at the Apple reunions (held every 100 moons, with the reunion in the third season), leading to a large in-fandom argument about whether the ponies are 17 or 25. Their maturity level indicates the lower number, while their roles in society requires the older, especially as that would require three of the main 6 to be business owners at 15. Notably, Rarity was fully grown during Sweetie Belle's flashback to her 5th birthday and Apple Bloom wasn't present in the flashback when Applejack got her cutie mark. Both of these suggest the older age.
** Popular fanon {{Hand Wave}}s include the possibility that ponies mature faster than humans (babies at least do as they [[FurryReminder can walk at a few weeks old]]), or that Equestria's lunar cycle doesn't directly correspond to our own; heaven knows [[PaintingTheFrostOnWindows the rest of their natural laws don't]].[[note]] How long a moon is supposed to be in a setting where the day/night cycle is manually controlled is a matter of some confusion, especially since the cycle has been interrupted several times in the course of the show.[[/note]]
** The birth-iversary cake in "Pinkie Pride" seems to suggest that a) Rainbow Dash is 21, b) Rainbow Dash is 31 (if the candles go all the way around the tiers, or c) the decorator(s) just like(s) putting candles on a cake without regard for representing years by them. In "Parental Glideance", a fillyhood flashback shows Dash's parents in late 80s to early 90s fashion, suggesting that she's in her 30s (presuming their 80s was as long ago as in the real world).
** Spike, who is several years younger than the rest of the main cast but apparently ''older'' than the other children in the show. He lives with Twilight Sparkle and basically acts as her younger brother, but unlike the other younger characters he can be left on his own for long periods of time (even taking over another's duties), and, rather than going to school, has a job as Twilight's assistant. All the while still being considered a "baby" dragon and sounding like a child or young teen. WordOfGod states that Spike is a teen/young adult in pony years but a pre-teen in dragon years.
** Cheerilee was a teen in TheEighties which suggests she is around the same age as Shining Armor (who is presumably in his late twenties or early thirties). "Parental Glideance" shows that Rainbow Dash was a kid around this same period, also suggesting that Cheerilee is older than the main characters. Cheerilee however was a filly at the same age Rarity and Pinkie Pie were. Despite Pinkie and Rarity's appearances, they're not implied to be much older than the rest of the Mane 6 (as mentioned, probably in their early to mid twenties).
** The physical ages of Celestia and Luna are hard to figure out. It's assumed ImmortalityBeginsAtTwenty, however Lauren Faust has suggested that Luna is still growing. However, she is treated as an adult rather than a teenager and her voice is mature. She's also had ShipTease with Big [=McIntosh=] in the comics. Celestia is similarly vague. She could be anywhere from her early twenties to her late thirties, possibly even forties. The age gap between Celestia and Luna has yet to be specified either. Fan opinions range from them being 3-5 years apart or 7-10 years apart.
** Ponies in general are hard to pin down in terms of age. The ones you might assume are all about the some age when in the present day may be either adults ''or'' foals in flashbacks. There are even characters who are adults in pre-Rainboom events such as the Summer Sun Celebration that inspired Twilight Sparkle to study magic, but fillies in post-Rainboom events such as the party that inspired Cheese Sandwich to become a party pony.
** The characters also age inconsistently, even in the same episode. In "Appleoosa's Most Wanted," for instance, the judges looked exactly the same during Trouble Shoes's childhood as they do in the present day when Trouble Shoes is an adult. It is possible, however, that the ponies are very long-lived, reaching their fully grown state and not changing much in appearance for a long time. In "Family Appreciation Day," for instance, Granny Smith is shown to be one of the founders of Ponyville itself, and she was already mature by then.
* ''Franchise/MyLittlePony'':
** This occurs throughout the generations. Characters are explicitly referred to as adults and several of them even have children, however they're notoriously immature and love playing with toys. Then again they ''are'' horses. The ''WesternAnimation/MyLittlePonyG3'' characters are especially hard to pin down ages for.
** Megan from ''WesternAnimation/MyLittlePonyTVSpecials'' and ''WesternAnimation/MyLittlePonyAndFriends'' looks somewhere between ten and fourteen. She has younger siblings who seem under ten.
** All the main characters in ''WesternAnimation/MyLittlePonyTales'' go to school, which would put them anywhere from six to sixteen. Sweetheart was the only aversion, celebrating her tenth birthday in "Happy Birthday, Sweetheart".
* ''Franchise/AlvinAndTheChipmunks'': Alvin, Simon and Theodore, as well as Brittany, Jeanette and Eleanor are obviously intended to be the chipmunk equivalents of human children. Throughout the franchise's history, though, they have cycled through all three stages of schooling (elementary, middle, high) with no visible signs of aging.
* WesternAnimation/BettyBoop appears to be an adult or young adult, but in "WesternAnimation/MinnieTheMoocher" she is running away from home because her parents grounded her when she didn't eat her peas. She is implied to be a teenager, and she can be between 16 and 19 in most shorts.
* It is difficult to tell if Piglet in the Disney versions of ''Franchise/WinnieThePooh'' is supposed to be a child or an adult. His proper name and his short stature should imply that he is young, but his relatively mature personality suggests that he may be significantly older than Roo.
* HBO Family sometimes airs a show called ''El Perro Y El Gato''. The two protagonists seem like adults but in one episode the dog asks the cat what he wants to be when he grows up, and the dog says he wants to be a veterinarian.
* Gwizdo of ''WesternAnimation/DragonHunters''. In TheMovie (which was a prequel to the series) he's established as a homeless adult; in the series he lives in an inn and has apparently been staying there since the innkeeper's daughter Zoria (who is around 18 now) was a child, which would mean that he's quite old. Yet appearance-wise he barely looks over 20 and in "The Isle of Mist" [[spoiler: when he ends up in a FountainOfYouth for a few seconds he immediately reverts to a young child even though the monks before him had to bathe in it for several minutes just to revert to their thirties]].
* '' WesternAnimation/TheSimpsons'':
** Jimbo, Dolph, and Kearney. They are implied to be teenagers, but apparently attend Springfield Elementary. Kearney on the other hand, while he has a very screechy voice and acts like a teenage bully, he also has a ''son'' of his own, is divorced and according to Otto (who one episode suggested was 30 or so during the show's early seasons, putting his birth date at about 1960), they were in [[HeldBackInSchool 3rd grade together]]. Kearney, oddly enough, was shown in an [[EarlyInstallmentWeirdness early episode]] trying to buy beer with a fake ID and assumed name. Later, he's shown to remember Watergate (1973-4), the nation's bicentennial celebration (1976) and is also able to openly go for a drink at Moe's. Of course, the first incident was before they decided that his advanced age and apparent multiple failures to complete the sixth grade were a RunningGag. Also, one episode shows that Jimbo is ''bald'' under his knit cap.
** And then there's Mr Burns...usually treated as being just on the high side of 100 years old, but one throwaway gag had him mentioning his birthplace: '''Pangaea'''. In the early years (1989-1993), when the show was more realistic, he gave his age as 81, suggesting he was born in the decade just prior to UsefulNotes/WorldWarI.
** Homer's father, Abraham "Grandpa" Simpson is a pretty strong example. He was old enough to serve in [[UsefulNotes/WorldWarII the second World War]] and is apparently around Mr. Burns' age, give or take a few years younger, as both men had served together. Also, it's been lampshaded in a few episodes that not even members of his own family are aware of how old he truly is. In "The Mansion Family", during a moment in a local awards show that was trying to determine who the oldest resident of Springfield was, he reports his age as less than 90, greater than 80, [[ScatterBrainedSenior and less than 70]].
* ''WesternAnimation/BeverlyHillsTeens'':
** Chester [=McTech=] is younger than most of the cast, but by how much is never specified.
** Whilshire looks like a teenager like the rest of the cast, but he's almost never seen attending school with them and apparently has a full time job as a valet/chauffeur. This was most likely done to make his crush on the obviously teenage Bianca less {{squick}}y.
* It's hard to pin an age onto the ''WesternAnimation/StrawberryShortcake'' characters. They look like preteens both in their 2003 and 2007 designs, despite the fact Apple Dumplin' aged noticeably at least six years. It's made even more confusing by the fact the later episodes involve the characters getting jobs, moving out, and driving cars but no one looks over fourteen. The 2009 is equally bad, with the characters owning their own stores but looking no older than fifteen. Even prior to this, they lived in their homes, planned their own sleepovers, and otherwise generally managed their own lives and there were no parent characters shown. In "Baby Takes the Cake" from the 2003 series, Strawberry Shortcake [[BreakingTheFourthWall warns viewers]] to leave certain dangerous things related to cooking like using knives or handling a hot stove to an adult. Which would seem to be her way of suggesting that she is one.
* Ami and Yumi from ''WesternAnimation/HiHiPuffyAmiYumi''. They are assumed to be adults like their real life counterparts but the art style makes them look like children and they act like teens.
* The ''WesternAnimation/{{Popeye}}'' characters don't have their ages revealed, though "Goonland" and "Popeye, the Ace of Space" imply that Popeye himself is around 40, while "The Man on the Flying Trapeze" has Olive being called "a maid in her teens". Also in "Puttin' on the Act" (from 1940), it's shown that Popeye and Olive had an 1890s vaudeville act.
* ''WesternAnimation/TotalDrama'' has a downplayed case with [[DramaQueen Blaineley]]. She is certainly elder to the original twenty-four contestants (who are around 17 in the third season), but it is not clear how large the age difference really is. She has a hosting job with both one adult and two teenagers, ends up briefly competing for the money alongside more teenagers, gets ShipTease with both adult [[ScaryBlackMan Chef Hatchet]] and teenaged [[BigFun Owen]], and admits to having crushes on [[InformedAttractiveness Justin as well as Alejandro]], who are both teenagers.
* In ''WesternAnimation/TheBeatles'' cartoon, the Fab Four themselves are in their moptop-era designs, meaning they're meant to be very young adults. However, a few episodes have them refer to themselves as teenagers, and yet another episode has them at a legal drinking age. It should be noted that it is possible to be all three simultaneously in Britain, where 18 is the drinking age and the age when one becomes an adult.
* It's never stated how old the human main characters of ''WesternAnimation/TheGrimAdventuresOfBillyAndMandy'' are supposed to be, and their school seems to combine elements of elementary school and junior high.
* The chalk drawing characters in ''WesternAnimation/ChalkZone'' are technically as old as when they were first drawn (for example, Snap turns two in "Lost in Chalk" because it marked two years since Rudy first drew him), but most of their physical/mental ages are still left vague. While Snap lives on his own and has been shown driving in a few episodes, he appears to be around eight to ten physically and mentally.
* The fairies in ''WesternAnimation/TheFairlyOddParents'' are immortal and have been alive for millions of years, however it's unsure how old most of the characters are in "human" terms, as well as physically and mentally, through Cosmo and Wanda come off as 30-somethings. Also, Tootie's age seems to be a bit debated. In one tie-in book from 2004, she's stated to be eight (making her two years younger than Timmy). However in some material, she's stated to be ten.
* While most of the characters on ''WesternAnimation/{{Recess}}'' are given ages, what age Cornchip Girl is and what grade she's in was left ambiguous. In "One Stayed Clean" she's shown among the kindergarteners, though this may have been accidental as she was shown running away from them earlier. Most episodes suggest she's in between grades first and third, but has been confirmed not to be in the same grade as the main six. Most fans tend to place her around seven.
* On ''WesternAnimation/{{Maisy}}'' the characters, a cute female mouse and her friends, go where they want, do what they want, [[UniversalDriversLicense drive cars, fly planes]], take their own baths, etc. Really, there's nothing explicitly indicating that they aren't adults, other than their very childlike appearance, childlike babble speech and tendency to play with toys and stuffed animals (not that adults don't ever do that last one, of course.)
* ''WesternAnimation/StevenUniverse'':
** Steven and Connie's ages were debated for a long time among fans, and generally thought to be somewhere between 8 and 12. They're both [[PintSizedKid very short]] and Steven is also quite immature. More than a year passed in-universe, without either visibly aging, before "Steven's Birthday" specified that [[OlderThanHeLooks Steven was turning fourteen]], though he hasn't changed much since he was eight, likely because of being a HalfHumanHybrid. Connie, who says that she's "twelve-and-three-quarters," is rather stunned by this news.
** Sadie and Lars have been working at Big Donut for two years, and in America most chain stores will only hire people older than sixteen. They don't seem to have any adult supervision at their job either. "Sadie's Song" states that she never went to prom, so she's presumably out of high school at the least. Lars has mentioned he's a teenager, and is apparently still in high school, meaning that he's probably either eighteen or nineteen.
** Gems technically have [[TheAgeless no physical ages]], however most look like adults. Ruby and Sapphire are both the same height as Steven, Ruby is hot-headed and unstable like a child, and unlike Amethyst they have childish bodies. Fans are torn whether they're supposed to look like little kids or are short, small chested women. [[spoiler:It doesn't help that their fusion, Garnet, is clearly an adult.]]
** Amethyst's age is pretty vague too. She's short and childish, but her voice and figure suggest she's at least the equivalent of a teenager and "Story For Steven" revealed she appeared vaguely less mature around when Greg Universe met Rose Quartz (though not any shorter, despite how it seems). Interestingly, she is the only Gem so far who's actual chronological age is roughly given: [[spoiler: around 6000 years, making her the youngest known full gem so far, yet even this is just an educated guess. All that's known so far is that the Kindergarten Amethyst was born in was shut down 6000 years ago and that she wasn't present at a certain battle that took place 5000 years ago, leaving her exact age ambiguous.]]
** Peridot is TheNapoleon, has an immature personality, and is younger than most of the other Gems. This leaves an ambiguity to how old she is supposed to be. Amethyst's age? Younger? Older? Lapis mentions in "The New Crystal Gems" that both her and Peridot are "thousands of years older than you [Connie]", but that's still vague.
* None of the ''WesternAnimation/{{Jem}}'' characters have confirmed ages. All that is given is Kimber is the youngest and the others are somewhere in their twenties. The series bible states Kimber is three years younger than Jerrica but that doesn't say much. We never see her show signs of being in high school so we can assume she already graduated and is either eighteen or nineteen. The IDW [[ComicBook/JemAndTheHolograms comic reboot]] averts this trope by clealy showing ages in the character bios.
* Ember from ''WesternAnimation/DannyPhantom'' has been suggested to be in her twenties by WordOfGod despite her general persona and looks seeming more like a rebellious high schooler. She is called a teen in her first appearance as well.
* On ''WesternAnimation/TootAndPuddle'', Toot and Puddle live together on their own and do stuff like travel the world. Yet they seem to have a childlike quality about them and sometimes don't seem to know stuff that an adult should already now. For example, in "The Legend of Pocket Hollow," when Otto tells Puddle that a story of his is "just a legend," Puddle asks what a "legend" is.
* In ''WesternAnimation/ThreeTwoOnePenguins'', it's never explicitly stated or even implied how old the Penguins are. Since they're penguins, their ages can't be determined by their appearances alone. If their ages are determined by their voices and how long it's been since Bert Bertman graduated from the Federation Academy, their ages would be from late twenties to early thirties.
* ''WesternAnimation/TheLionGuard'':
** Kion and Kiara are not littermates but appear to be of similar ages, despite Kiara explicitly being older. Kion has a tuft of mane growing already and has gotten TheTalk however both siblings have the same generic 'cub' design.
** Fuli looks like a cub but is apparently old enough to have left her mother (unless her mother [[MissingMom died]]). She lives alone and hunts alone.
** Bunga is obviously young but flashbacks show him even younger when he was taken in by Timon and Pumbaa.
** Vitani, Kovu, and Nuka all feature {{Role Reprisal}}s from their movie. The problem is that Kovu uses his ''adult'' voice but has his cub design. The impression is that of [[VocalDissonance a preteen with a grown man's voice]]. Some fans have theorized that he is in his early teens though and that he looks a bit older. This only makes Kiara's age more vague as she seems older than Kion, also uses the cub design, but is younger than Kovu.
* ''WesternAnimation/RainbowBrite'': Rainbow barely reaches ten year old Brian's hips but is old enough to have ShipTease with him. She and the other Color Kids act awfully mature for their looks and [[MinorLivingAlone live alone]]. There are implications that Rainbow has lived in Rainbow Land for years which brings to question [[TheAgeless if she even ages]].
* The main characters of ''WesternAnimation/ChipNDaleRescueRangers'' qualify, most notably Gadget Hackwrench. The closest the series ever gets to specifying the characters' ages is that two episodes imply that Monterey Jack is much older than Gadget, Chip, Dale, and Zipper.
* The exact age of WesternAnimation/FelixTheCat is never made clear, with the ambiguity of it most notable in the Trans-Lux television series, where he is depicted as living on his own and being trusted by the Professor to look after his nephew Poindexter, but is occasionally referred to as a kid.
* How old are the live-action cast in ''WesternAnimation/BluesClues'' supposed to be? Apparently Steve is an adult, maybe a [[DawsonCasting late teenager]], as he eventually leaves for college but what about his brother? Joe acts immature like a kid but lives alone and is played by an adult.
* The age of the titular trio in ''WesternAnimation/ThePowerpuffGirls2016'' is this. In the [[WesternAnimation/ThePowerpuffGirls original show]] Blossom, Bubbles, and Buttercup were explicitly five years old biologically (but younger due to being {{Artificial Human}}s), however the reboot is more ambiguous. They are in an elementary school and their class teaches elementary level subjects however their kindergarten teacher Ms. Keane is still their teacher. Their classmates look older than six, many of the students outright look like middle schoolers, and in one episode the girls were teased by classmates for "looking like babies". They sound older and act older but still use the same designs they did when they were five. According to one episode the girls have had five Picture Days, which pins them around ten or eleven years old. However, their classmate Princess is explicitly six. It's made even more confusing when a fourth Powerpuff Girl named Bliss appears who is explicitly a teenager and looks taller and curvier than the others.
* ''WesternAnimation/MikeLuAndOg'': Mike's age is unstated, but looks to be around 10 to 12. Lu says she's 10 in "High Rise", while Og celebrates his 7th birthday in "The Great Snipe Hunt".
* The entire cast of ''WesternAnimation/{{Kaeloo}}''. One episode stated that teenagers and adults weren't even allowed in [[CrapsaccharineWorld Smileyland]], yet Kaeloo is a frog and not a tadpole, Pretty behaves like a [[BrattyTeenageDaughter teenager]], and Mr. Cat behaves like an adult (and his voice sounds like one too). Their ages seem to change between episodes, too. In an early episode, Kaeloo mentions how difficult going through puberty was for her, yet in a later episode she is stated to be pre-pubescent. Also, Mr. Cat, despite coming off as an adult, is actually less than 13.
* ''WesternAnimation/GummiBears'': The exact lifespan of the Gummi Bears is never made clear but without ever saying the exact ages the show implies that: Gruffi, Zummi and Grammi are adults. On this, Zummi is clearly the older and Grammi is sometimes referred by non-gummis as “the Old Lady Bear”, although she and Zummi were cubs at the same time and friends in their childhood so probably have similar ages. Tummi is in his late teens or is a young adult as he is often seeing playing with the cubs but is treated more closely to an adult (one episode has exactly this as the conflict, as Tummi feels he is considered too young to be trustworthy but too old to be allow to play like the cubs), Zunni is in her early teens, Cubby is a pre-teen (and both are considered “cubs” although Zunni is treated accordingly to her adolescent status) and TheSixthRanger Gusto is according to Tummi from his same age but is mentally more mature.[[note]]Probably because he had to survive on his own on an island for twelve years.[[/note]]
* PlayedForLaughs in ''WesternAnimation/OKKOLetsBeHeroes'': upon learning that his mom gave up being a superhero "6-11 years ago," K.O. gasps "[[ImmediateSelfContradiction That's exactly how old I am]]!"
* On ''WesternAnimation/ToddWorld'', the main characters all seem to largely conduct their own affairs, roaming freely throughout [=ToddWorld=], handling their own baths and scheduling activities and stuff. Yet they're also very childlike, often engage in pastimes generally enjoyed by children, and in "Snack Happy," Stella mentions having a special tuna sandwich that her mom made her. While there are adults on the show, the only parent that's ever seen is Sophie's cat, who is an adoptive mother of puppies.
* ''WesternAnimation/SpongeBobSquarePants'': The ages of [=SpongeBob=] and Patrick are inconsistent. Are they adults? Children? Immature teens? {{Man child}}ren? Thanks to the NegativeContinuity, we may never know.
* On ''WesternAnimation/BeatBugs'', the characters have their own homes and manage their own affairs like adults, yet still exhibit child-like behavior, especially with Buzz who is clearly intended to be more of an AudienceSurrogate in terms of the show's target age group. Show creator Josh Wakely has stated that the lack of parents is very much intentional and intended to set the show apart from others by making it so that the characters have to solve their problems themselves because there aren't parents there to fix things.
* ''WesternAnimation/ReadyJetGo'': While it is known that Mindy is 4 years old, it is unknown how old the other kids are. It is likely they are in their mid-to-late preteens, but it is unclear. Sean knows what payload is, but somehow does not know what asteroids are. Meanwhile, due to the inconsistency with the animation, Mitchell is either taller or the same size as Mindy, and does not know how to spell "electric engine" yet can make a replica of Saturn V and somehow managed to acquire an ion drive.

[[folder:Real Life]]
* Charo. She was born January 15 of either 1941 (what her birth certificate says), 1945 (what Wiki/TheOtherWiki says) or 1951 (what she says).
* Both Music/{{BlueStahli}} and Music/{{Celldweller}}. Due to the fact that they never mention their age nor are their ages listed on any website.
** Klayton is, however, [[http://www.metal-archives.com/artists/Klayton/163527 rumored]] to be [[OlderThanTheyLook 50, of all ages]], but he has [[https://www.facebook.com/celldweller/posts/10151024436601672 denied]] said fact, but whether or not he's being honest is up to debate.
* [[Film/TheRoom Tommy Wiseau]] is famously secretive about his age. In 2010, he claimed to be 41, but other sources list his birth year as 1955, which would make him 55 as of that year.
* The author Sydney, Lady Morgan was very vague about her age, maintaining that she was born in 1785 when it was probably 1781. Her death certificate (in 1859) gives her age as "about 80".
* UsefulNotes/IdiAmin's birth date is unknown, guessed at maybe 1923, 1925 or 1928.
* Boxing great Sonny Liston is another example. He was born to a poor sharecropping family in Arkansas either just before or during the Great Depression, and his birth was not officially recorded.[[note]](The state didn't make birth certificates mandatory until 1965.)[[/note]] Statements by him, his mother, and other family members were often contradictory, supporting dates anywhere from 1927 to 1933. He eventually settled on a 1932 birth date for official purposes, but [[YoungerThanTheyLook an aged appearance]] lent credence to rumors of the earliest dates. The mystery of Liston's birth date will almost certainly go unsolved, but it's now most likely he was born sometime in the summer of 1930.[[labelnote:Evidence]]When that year's U.S. Census was publicly released in 2002, Sonny (birth name Charles) wasn't listed. Ten years later, the 1940 Census was released, which listed Charles as a 10-year-old. Lending further support to a 1930 birth date is the census recording of Sonny's next-older brother Curtis. When the Liston family was recorded in the 1930 Census that April, Curtis was listed as between 6 and 12 months old. In April 1940, when census takers visited the Liston farm again, Curtis was listed as 11, although most likely still 10—their mother may well have counted her children's years from birth inclusively.[[/labelnote]]
