->''"...And then you've got the ones who are just waiting for their parents to die. My one friend is like, 'This'll all be mine one day,' and I'm like, 'What are you talking about? Your mother is only 54. What are you gonna do, poison her?'''"
-->-- '''Creator/ChrisRock'''

A stereotypical HollywoodNerd who, [[ManChild despite being a grown adult is still an adolescent]] right down to living with his parents. While the decor of their PosterGalleryBedroom is subject to the tastes of the character, be sure there will be a computer to communicate with the outside world. It's always PlayedForLaughs as an [[AcceptableLifestyleTargets acceptable lifestyle target]]. More importantly, the subject is AlwaysMale. There is little stigma to a female character living at home, and in some cultures it might even be expected. This makes the trope a huge DoubleStandard against men as well (but see below).

The guys who are depicted in this condition usually fit into one of the following:

* Lazy and unwilling to earn a living for himself.
* Childish and requires everything to be done for him.
* [[NerdsAreVirgins Can't get any]] and hasn't moved out to start a family.
* Technically ''unable'' to earn a living for himself. (i.e. unable to get a job)

Thank goodness those don't sound like nerd stereotypes, or [[MostTropersAreYoungNerds we]] could be in real trouble. This trope has become much, '''MUCH''' less stigmatizing in RealLife, however, where the economy has been sending more and more adults back to their parents' homes. [[http://www.msnbc.msn.com/id/38364681/ns/business-economy_at_a_crossroads And if this article is any indication, this trope could even become discredited at some point in the future.]]

Note that living with one's parents is a stigma mainly in the USA and other Anglosphere countries, where working-age adults are expected to live on their own, so [[ValuesDissonance this trope shouldn't be applied to characters from cultures where this is the norm]].

For a more serious treatment of this as a social problem, see {{Hikikomori}}. Not to be confused with MadwomanInTheAttic. Compare TheHermit.

[[folder:Comicbooks]]
* One of the outcries toward the infamous {{Spider-Man}} story '' OneMoreDay'' is that Peter Parker is now more relatable because he is a unmarried, perpetually unemployed man who lives with his aunt. [[UnfortunateImplications Smooth work there...]] (He has an apartment now.)
** Hilariously, Screwball accused him of living by his momma. Spidey shouted "No", mentally adding "auntie, not momma".
* TheDCU depicts Superboy Prime-- an alternate universe version of Superman with [[PsychopathicManchild stunted emotional and physical development]]-- as a StrawFan with near unlimited power and no one to oppose him. [[TakeThat He chooses to live in his parent's basement forcing them to cook and clean for him, while he trolls DC Comics message boards.]] He was pretty [[OmnicidalManiac busy]] before, though.
* MauveShirt Jason Michaels from the ''[[HackSlash Hack/Slash]]'' story ''Land of Lost Toys'' lived with his mother, in a room filled with action figures. His best friend [[AsianAndNerdy Chris]] (who would go on to become a main character) was his "roommate" (he lived in the basement).
* Creator/MarkWaid once tweeted that he stopped using this as an insult when he realized that "thirty-year old who lives in his parent's basement" also applies to ''Franchise/{{Batman}}''.
[[/folder]]

[[folder:Film]]
* In ''{{Mallrats}}'', comic loving slacker Brodie lives in his mothers basement. [[spoiler: His girlfriend dumps him for this reason]]
* In ''Film/MenInBlack 2'', Agents J and K get intel from a conspiracy theorist guy who lives in his mom's attic. They claim to be from his therapy group.
* ''[[Film/DieHard Live Free or Die Hard]]'': [[spoiler: "Warlock's" "Command Center".]]
* In ''ThePallbearer'', David Schwimmer still lives in his childhood bedroom.
* Wayne of ''WaynesWorld''. In the second movie when he and Garth move into their own place.
* The movie ''FailureToLaunch'' deals with a group of grown men living with their parents who exhibit stereotypical nerd behavior.
** Subverted though, in that the 'nerdiest' of the group actually owns the home he lives in, and took in his mother because that's what you do when your mother has nowhere else to go. In fact everyone in the group but the main character has some sort of technicality which makes them not ''really'' live with their parents, which is used to explain why only said main character is [[AnimalsHateHim attacked by chipmunks and dolphins]].
* Subverted in ''Film/GalaxyQuest'' when Jason Nesmith is contacted by the Thermians. He thinks that they're particularly rabid fanboys who have built an exact replica of the the ''Protector'' in their parents' basement. He's only two-thirds right.
** Guy Fleegman, whose character played a RedShirt in the [[ShowWithinAShow in-movie TV-show]], can be spotted in one scene hitting on a young woman who responds with "but you live with your mom!"
* Speaking of Tim Allen. His role as Zoom in ''ZoomAcademyForSuperheroes'' has him meeting his fans and asking how many of them still live in their Mom's basement. All but ChevyChase raise their hands. This is followed by what [[http://www.agonybooth.com/recaps/Zoom__Academy_for_Superheroes_2006.aspx?Page=3 the movie's Agony Booth Review]] refers to as ''"Awkward Silence Which Is Supposed To Be Funny[[TradeSnark ?]]."''
** A wonderful line granted, but the idea was best expressed in a SNL sketch with Shatner delivering that as well as the inquiry of how many attendees at the convention have even kissed a girl. Priceless.
* In ''Film/EightMM'' [[spoiler:the killer]] lives with his mom, [[spoiler:who is completely oblivious to his problems]].
* The whole plot of ''{{Tanguy}}'' involves exasperated parents who try to get their grown son (the title character) to move the hell out so they can have their own lives back.
** This French film appeared to have hit a chord with the public, as the name "Tanguy" has basically become a generic word for BasementDweller in French-speaking countries, where it's not uncommon to hear people complain that their son is a Tanguy.
* Dave's cousin Toby from ''Film/AlvinAndTheChipmunks: The Squeakel'' who lives in his grandmother's basement and plays video games all day.
* Subverted in ''TransformersRevengeOfTheFallen'' by Agent Simmons. When questioned about living with his mother, he states "She lives with me. [[TruthInTelevision There's a big difference]]."
* In ''BadlyDrawnRoy'', Roy continues to live at home because he can't hold down a job despite being in his thirties, which causes [[spoiler:friction and arguments between him and his parents as well as [[{{Mockumentary}} running away from the camera]]. He eventually checks himself into a rehabilitation center because of his depression]].
* In ''BabyBoy'', Jody's mom calls him out for being a grown man living at home, until he points out that ''she'' never moved out and simply inherited her house from her own mother.
* Stephen in ''Film/TheScore'' lives in a HackerCave in his mother's basement.
* ManChild Alan from ''TheHangover'' films refers to himself as a stay at home son. He gets his meals served to him in his room by his mother.
* Teddy in ''Film/SaveYourLegs'' is living in his mate Stavros' garage. Stavros' wife does not approve of this arrangement.
* Subverted early into ''Film/{{Harvey}}''. Myrtle Mae complains to her mother how her uncle Elwood does nothing but lounge around the house all day and still lives with his older sister. Veta promptly corrects her that Elwood inherited the entire family fortune so ''they're'' the ones living with ''him.''
[[/folder]]

[[folder:Literature]]
* Subverted in ''TheHelp''. The big publishing hotshot is disgusted to learn that our heroine lives with her mother. The heroine is actually taking care of her mother as she dies of cancer. Oops.
* In the ''Franchise/DoctorWhoExpandedUniverse'', Fitz's initial circumstances may count as a subversion: he's a single, 27-year-old, immature geek with a lousy job whose 65-year-old widowed mum lived with him before she moved into a sort of insane asylum shortly before he's introduced. She's generally mentally unwell and prone to delusions of being the devil and so on, in addition to being rather sickly and apparently prone to "taking the back off one-armed bandits", and therefore needs him to look after her.
* Played with in ''{{Literature/Freakonomics}}'' with the chapter titled, "Why Do Drug Dealers Still Live With Their Moms?"

[[folder:Jokes]]
* "{{Batman}} may ''call'' it "The Batcave", but that doesn't change the fact that he spends most of his time in his parent's basement"
[[/folder]]

[[folder:Live Action TV]]
* The TropeMaker is likely Creator/WilliamShatner's "Get a Life" sketch on ''SaturdayNightLive'', in which he made reference to how the ''Franchise/StarTrek'' fans should [[TakeThat get a life and move out of their parents' basements]]. That sketch may have single-handedly [[strike:invented]] popularized ''every'' Trekkie stereotype.
* There was a series called ''[[http://en.wikipedia.org/wiki/Get_a_Life_%28TV_series%29 Get A Life]]'' starring ChrisElliot that aired on Fox in the early 90's. Elliot's character was an epitome of this trope, although he lived in an apartment over his parents' garage, rather than in the basement.
-->ChrisElliot plays Chris Peterson, a carefree, childlike bachelor who refuses to live the life of an adult. At the age of 30, Chris still lives with his parents and maintains a career delivering newspapers (the ''St. Paul Pioneer Press''), a job that he has held since his youth. He has no driver's license (instead, riding his bicycle wherever he goes). He is depicted as being childish, nave, gullible, foolish, occasionally irresponsible, and extremely dimwitted. Chris is often the subject of abuse from his friends and family. He is often seen dancing (involving a silly back-and-forth step while swinging his arms) to the piano tune "Alley Cat" by Bent Fabric. His lack of intelligence is exaggerated to absurd levels: at one point, he tries to leave his parents' house but is unable to operate the front door. He also fell out of an airplane after opening the plane's exterior door, believing that it led to the restroom.
* ''{{Series/CSI}}'' episode "A Space Oddity" plays the HollywoodNerd image ludicrously straight by showing two guys living in a reconstruction of the ship from "[[Franchise/StarTrek Astro Quest]]" in their mother's attic.
* ''Series/{{Ghostwriter}}'' episode "Into The Comics": Manny Gite runs his evil operation from his mother's attic, where he resides.
* Played with in ''Series/StarTrekDeepSpaceNine''. When what's left of the Cardassian resistance movement are on the run on Cardassia, they end up hiding in the basement of the house Garak grew up in; complete with an overbearing mother-figure who feeds them and makes them do chores. Garak shelters there, and if it never definitely says she is his mother, she acts damn close. Still, [[MagnificentBastard he]] [[MysteriousPast certainly]] [[ChronicBackstabbingDisorder is not]] a shiftless [[AffablyEvil loser]].
* ''Series/BuffyTheVampireSlayer'':
** Xander Harris, who does not enrol in college during the fourth season and lives in his parents' basement, where he pays rent. He gets his own place in season five. By season seven, everyone seems to be living in the Summers household.
** Also the nerd troika of season six, whose evil headquarters is Warren's parents' basement.
** Spike in parts of Season 4 and 7. ("I'm chained in a bathtub, drinking pig's blood from a novelty mug!")
* ''TheDrewCareyShow'': Drew had long been living in his parents' house, which he bought from them. When they have to move back in, he's forced to live in the basement. Naturally, he comments on being a 40-year-old man who lives in his parents' basement.
* Howard from ''TheBigBangTheory'' lives in his old bedroom instead of the basement, but otherwise fits this trope to a T. However, he and his family are Jewish, which is one of the cultures where adults living with their parents before they get married is considered normal.
** Especially prevalent when he ''finally'' gets a girlfriend, Bernadette, and expects her to move in with him and his mother.
-->'''Bernadette''': Does your mother always cut your steak?
* Frank on ''[[Series/ThirtyRock 30 Rock]]'' lives with his mother and pays her rent. It hasn't been mentioned if he actually lives in her basement. Subverted when he almost moved out to become a lawyer. (Jack put a stop to this after learning that all of Frank's male relatives were lawyers for TheMafia and consequently met bad ends.)
* In one episode of ''Series/{{NCIS}}'', Tony and Ziva interviewed the web master of a porn site who lived in his mother's basement. He also collected ''Franchise/StarWars'' toys as "investments" and met the site's owner on his paper route. If memory serves, his mother wanted to bring them snacks.
** Another episode, featuring an episode long, city-wide BigBlackOut, starts out with a man in his thirties who's playing a computer game when the Internet connection is suddenly lost. He immediately shouts for his mom, who he apparently lives with.
-->'''Man:''' [[BigNo Nooooo!]] Moooom! MOOOOOOM!!!
* Similar to this, people routinely make fun of the title character of ''{{Frasier}}'' for living with his father, causing him to make the same reply of "He lives with me!" Except that this is actually the case... Frasier's father moved into Frasier's apartment to be taken care of, not the other way around. Oddly enough, the ''writers of the show'' seem to occasionally forget this.
* The most extreme example of this is Ted from ''{{Scrubs}}'', the pathetically inept sad-sack attorney who not only lives with his mother, but [[{{Squick}} shares a bed with her.]]
* In ''{{Seinfeld}}'', George lives with his parents during most of season 5 because he can't find a job.
* ''EverybodyLovesRaymond'': Robert Barone is forced to move in with his parents-- even though he bought their house from them, and ends up having to give it back to them after he loses his apartment, he's cast as the "loser" because he's a man in his mid-40's living with his parents.
** The first time he moved out, he ended up in an apartment above the garage of the Jewish versions of Frank and Marie. They even cooked his dinner, bossed him, and ignored him in order to pay attention to Ray.
* ''Series/CriminalMinds'':
** The accomplice of the killer from "Extreme Aggressor" had shades of this, since he lived with his grandmother and spent almost all his time in the attic; Morgan, after finding his bedroom, even says "This is a boy's room, not a man's".
** The [=UnSubs=] in "The Wheels On The Bus..." were implied to be this trope for much of their lives, since their parents had abandoned them.
* On Sci-Fi's ''Series/FlashGordon'' the title character lives with his mother and sometimes worries that he's falling into this trope. Everyone assures him that he's actually rather admirable because he moved back home to help take care of his mother when she was diagnosed with cancer.
* On ''MyNameIsEarl'', Earl tries to make up for poking a hole in his crush/babysitter's condom. He finds the girl, who has married the guy who got her pregnant, and they have an unemployed adult son who dropped out of high school and leeches off his parents. Earl decides to help him truly become an adult. HilarityEnsues.
* Bud Bundy in the later seasons of ''MarriedWithChildren''.
* Vinton Harper of ''MamasFamily'', despite being over 40 years old, and a single father of two children, who DO move out when they're old enough.
* Buster Bluth in ''Series/ArrestedDevelopment'' is a grown man still living with his mother. He is more or less incapable of functioning in the outside world.
* Invoked by Saba's characterization of [[Series/BigCatDiaries Chui the leopard]] when she finds he's still living with his mother about a year after they thought he'd have become independent. Obviously, being a leopard, he doesn't show the human-specific features of a BasementDweller, but he is living mostly off of his mother's kills when he's old enough to be on his own. Best guess about why? The local male (probably his father) seems to have gone missing and therefore wasn't around to drive him away and mate with his mother. Sadly, his mother Bella was looking kind of skinny from supporting her adult son as well as herself.
* During a hockey broadcast by [[{{CTV}} TheSportsNetwork]] in Canada, announcer Gord Miller and commentator Pierre [=McGuire=] were talking about ludicrous trade proposals they've read. Miller noted, sarcastically, "there are two types of people who make up proposals- 13-year-olds that live in their mother's basement, and 30-year-olds who live in their mother's basement."
* Don Pratt from a ''Series/MrShow'' show sketch. During his commercial, he tells the audience he can get anywhere within a 30-mile radius "anytime she doesn't need the car." Also when calling, "if [Don Pratt's] mother answers, hang up quickly!"

* The main character of Brad Paisley's ''Online'' lives in such a situation.
--> "When I get home, I kiss my Mom and she fixes me a snack \ Then I head down to my basement bedroom and fire up my Mac"
* Music/WeirdAlYankovic:
** "It's All About the Pentiums":
--->Hey fella, I bet you're still livin' in your parents' cellar\\

I should do the world a favor and cap you like Old Yeller\\

[[folder:Video Games]]
* Toni Cipriani in ''VideoGame/GrandTheftAuto III'' is a Mafia boss who still lives with his mom and frequently gets yelled at by her. Not that he's always lived with her; three years before the game he'd been living alone (and far away from Mama) for a while. He just had to move back in at her insistence - she can be very... persuasive.
** This is also part of the [[AcceptableEthnicTargets Italian]] stereotype of men, no matter how independent, tough or respected outside of the home, still are dominated by their mothers.
** The entire [=McReary=] family from ''[[VideoGame/GrandTheftAutoIV GTA IV]]'', all grown, live with their Ma with a single exception. Derek is a fugitive recently returned from Northern Ireland, Gerald is in and out of prison, Packie is a small-time thug, and Kate, wholesome and innocent, keeps their Ma safe. The odd man out, Francis, is deputy police commissioner.
** Jimmy De Santa from ''[[VideoGame/GrandTheftAutoV GTA V]]'' also fits this trope. He constantly sits up in his room, masturbates, smokes pot and plays video games without making an attempt to get a job or move out.
* Rowland in ''VideoGame/TheOrionConspiracy'' reveals himself as this. He says that he lived with his mother before coming to work at the space station. He is rather childish, immature, lazy, fat, has a chocolate addiction, and is a hypochondriac.
* Larry Laffer in ''VideoGame/LeisureSuitLarry'' lived with his mother until he one day came home and discovered that she had gone traveling and sold the house. Larry was 38 when this happened.

* According to Nelson, Frank and Lewis in ''FullFrontalNerdity''.
* In ''Webcomic/RealLifeComics'', while camping out in front of a store for a game, a guy, Greg's age, came by to sit in line. He didn't have anything else to do since his Mom's basement was being bug bombed and then he offered to play ''TabletopGame/YuGiOh'' cards with him.

** Doug and Rob moved out of their parents's house around the time of ''Film/TheRoom'' review. Then, they had a [[BigFancyHouse big and gorgeous]]. Now, they are married and live in different houses.
* Similarly, Wiki/{{Uncyclopedia}} articles assume that all the [[SelfDeprecation editors]] and [[TakeThatAudience readers]] must be basement dwellers.

[[folder:Western Animation]]
* In ''WesternAnimation/AdventureTime'', one of Jake and Lady Rainicorn's sons, T.V., is revealed to be this in the episode "Jake Suit". Jake expresses his approval.
* Frugal Lucre of ''WesternAnimation/KimPossible'' operates his schemes of world conquest from his mother's basement where he lives.
** Taken two steps further, when the heroes gain access to his 'lair' not through their usual MO of breaking in through the roof or ventilation shafts, but by knocking on the front door and asking his mother if he was home, and then when Lucre and the heroes are gearing up to fight in the basement a few moments later, they're interrupted by his mother bringing a tray full of snacks and juice for her son and his 'friends'.
* ''FairlyOddparents'' episode "Big Superhero Wish": The middle-aged writer of the [[ColorCharacter Crimson Chin]] lives his with his mother and receives a magazine called "Geeks Who Live With Their Mothers Monthly".
** Not that [[SadistTeacher Denzel Crocker]] is any better...
* ''WesternAnimation/BatmanTheBraveAndTheBold'' episode "Night Of The Huntress": The middle-aged "The Calculator" operates his evil ventures from his mother's basement. When Huntress comes to bust him, his mother is all too pleased that there is a girl here to see him.
* ''WesternAnimation/CodenameKidsNextDoor'': "Operation M.I.N.I.G.O.L.F." Involved The Great Puttinski [[IncredibleShrinkingMan shrinking down]] Numbuh 2 and challengeing him in a mini-golf course complete with models of the world's monuments. The whole course is in his mother's basement. Numbuh 2 still wins.
* ''WesternAnimation/LegionOfSuperHeroes'' episode "Substitutes" has Porcupine Pete, who not only has his mom drive him and the other audition rejects around, but also has the best moment of his life ruined by his mother arriving and saying it's his ''nap time''.
* Coop from ''MegasXLR'' makes for a strange non-nerd (albeit very slacker) example. Upon learning that the MonsterOfTheWeek intends to destroy his house, he exclaims "My Mom's home! She'll ''kill'' me!"
* ''WesternAnimation/TheBatman'': Cluemaster even built his evil lair in his mom's basement.
* ''WesternAnimation/TheSimpsons'': Comic Book Guy is subject to GeographicFlexibility. Apparently someone thought this would make a worthy gag to have him living in his parent's basement after they'd ''already established'' that he lives above his shop (it's one of those business-on-the-first-floor-home-on-the-second-floor buildings common in smalltown USA).
** Most of the jokes about Seymour Skinner revolve around how he still lives with his beloved [[strike: [[MyBelovedSmother smother]]]] mother in middle age (although as with Frasier, he insists "she lives with me!"). Unlike in Frasier's case, he is not especially successful, she appears perfectly capable of taking care of herself, and she was living in said house before he came home from the war. So it's pretty clear his protestations are wrong.
* ''{{Futurama}}'' episode "[[ParodyEpisode Where No Fan Has Gone Before]]": Melllvar hits this trope dead center.
--> '''Melllvar's Mother:''' Melllvar! Dinner time!
--> '''Melllvar:''' Aw, but Mom, I'm playing with my collectibles!
--> '''Melllvar's Mother:''' Now!
--> (Melllvar groans and disappears)
--> '''Fry:''' All this time we thought he was a powerful super-being, yet he was just a child.
--> '''Melllvar's Mother:''' He's not a child, he's 34!
* A villain in ''WordGirl'', Chuck the Evil Sandwich-Making Guy, lives in his mother's basement. (He tried to move into his own lair once, but got too homesick and moved back.)
* ''WesternAnimation/TheVentureBrothers'': Henchmen #21 briefly lives and operates his own comics supply business out of his mother's house, before being called back by The Monarch.
* Oz from ''FanboyAndChumChum'' fits this trope to a T. He's an adult, action figure-collecting, obese comic book nerd who lives with his mother. They technically run a comic book shop together, although in "The Hard Sell" it's revealed they're unable to sell anything due to Oz's infatuation towards the items.
* In ''KingOfTheHill'' "The Witches of East Arlen", Bobby joins a group of "wizards" who appear to be basement dwellers as the leader Ward who looks middle aged lives in his mother's house.
* Wade from ''KickButtowski'', while not a nerd but a severe slacker, told Kick and Gunther that he lived in his step-mom's basement but she kicked him out...
** Turns out she lived in a trailer and the basement was just a hole in the ground underneath it.
* In ''LegendOfKorra'' Book 3 "Change" one of the new potential Airbender recruits is a 22 year old one of these. His Mother, despite the saying he's "Still trying to figure his life out" to try ans justify it, is ''delighted'' by the idea of Tenzin taking him to the Northern Air Temple just so she can get him out of the house.

[[folder:Real Life]]
* Former Polish Prime Minister Jaroslaw Kaczynski lived with his mother throughout his term of office. He isn't married, has a law degree, so apparently the Polish electorate didn't hold it against him. The stigma is generally less in Europe, whether because of a strong emphasis on family life (as in Italy), prohibitive property prices (as in the UK, though Italy also has this problem) or both (as in Poland).
* In the Netherlands it's generally seen as uncommon and somewhat overly dependent to still live with one's parents if one is comfortably in one's 20s and has some way of supporting oneself. Though some students living close enough to their educational facility continue to live with their parents, a decision often related to difficulties finding a place or Hotel Mama being more convenient and less costly, most students look down on this, especially if still done beyond the first or second year of one's studies, and prefer the freedom and independence of a grotty student room. Adults moving in with their ailing parents seems to be fairly unusual as well. There may be in-country cultural differences in this, though.
** The rising prices of student housing might be making an end to this, with students paying up to 600 for a grotty room.
** This being the [=BeNeLux=] equivalent of the US- dormroom or house-sharing trope, which is quite rare there.
* Because of the current recession it can get rather difficult to avoid this if you're a college student.
** For that matter, it can be difficult to avoid this for graduates, if you didn't choose a high-demand degree.
* The "move out when you are an adult" is a (relatively) recent phenomenon of post WWII America where everyone had four complete years of constant work, savings i.e. rationing, and GI Bill bonuses to boot. Prior to that most people lived in family units and only moved away when there wasn't enough room in the current dwelling.
** It was also a cultural norm for young men to move out as soon as they became adults in order to make it on their own and prove that they were real men (it's debatable on whether or not young women experienced the same thing or they lived at home until they met the right man to marry and move in with him). Nowadays (especially because of the lousy economy), most young adults stay at home with their parents or relatives until they have a stable income and be able to live on their own off of that.
*** The abovementioned cultural norm depended on your socioeconomic level. Working-class and farm girls as well as boys left home as young as eleven to get jobs in mills and factories, often sending part of their earnings to their families. Many factories had dorms for their child/teen employees. There were also independent rooming houses and protective societies for female workers.
* Japan has some [[{{Hikikomori}} serious social problems]] with this issue. Though shows like ''Anime/WelcomeToTheNHK'' sort of address the issue, the usual statement made is that {{Otaku}} culture is a product of these behaviours, and not a cause.
** It doesn't help that only about 12% or so of Japan is actually inhabitable, which leads to crowding and ''insane'' prices. Well, let's see, I could either bankrupt myself trying to live in my own apartment, or stay with my parents and not spend almost all of my income on rent and mortgages. Decisions, decisions...
* Some people also move home after leaving and failing hard. This happens to many people. Reality show phenom [[TheXFactor Simon]] [[Series/BritainsGotTalent Cowell]] had to move home after the FIRST time he hit it big and lost everything, according to at least one official biography.
* Living with their parents is a common practice in Latin America, since social, political and economic instability is the rule in most of the countries of the region, up to the point you have [[TheClan 3 or more generations]] living in the same house; not that this is so bad, in [[SocialServicesDoesNotExist nations where social care for old people is at best negligible]] sons end taking the responsibility to keep the house running along with their aging parents and relatives. Also, living in community makes things a lot easier in terms of paying the bills since you can buy wholesale merchandise.
** Interestingly the practice of having the family living close to someones has allowed some people to start [[FamilyBusiness family businesses]] which in turn [[EarnYourHappyEnding have improved the economy of their countries]]. Also, Latin American people will always have a safe haven in case of social or economic failure, which may or may not be related to why instead of [[DrivenToSuicide committing suicide]] or [[CrazyHomelessPeople ending sleeping in a park]] Latin Americans simply [[TacticalWithdrawal pull back to their parent's homes]] [[YouAreNotAlone to heal their wounds]] and [[AWorldHalfFull get ready for another one!]]
** In Middle Eastern nations, it is generally expected that children live with their parents until they get married.
** Same thing in the Mediterranean countries, Eastern Europe (see Poland above) and SE Asia. In some of the Mediterranean countries, there are also expensive property prices on top (Italy and Spain, to name two examples).
** Living with parents, and the concept of the joint family, is very common in India and the rest of South Asia. When some younger individuals live away from their parents, it often happens amongst villagers who travel to larger towns and cities to earn a living. Sometimes, people from richer families live away from their parents, but the trope bounces back when they own houses within the same area or even building.
* The extended family is the norm through almost all of human history. It's only very recently that the nuclear family - and the whole idea that a person moves out and starts their own family - became popular.
** This was more a result of the relative perception of prosperity of the Post-WWII years in the West. The nuclear family migrated slowly to the Far East from Western influences.
* DrPhil refers to these people as Moochers, and has done [[http://drphil.com/shows/show/29 four]] [[http://drphil.com/shows/show/520 specials]] [[http://drphil.com/shows/show/610/ on]] [[http://www.drphil.com/shows/show/1657 them.]]
* In early 2014 [[http://www.theguardian.com/news/datablog/2014/jan/21/record-numbers-young-adults-living-with-parents a study in Britain]] found that over a quarter of 20-34 year olds (640,000 people) were still living with their parents, and for every 10 women there were 17 men. Reasons for this include a rise in unemployment and shakier employment prospects (ie. more part-time and temporary full-time jobs, less permanent full-time jobs); high house prices and low living wages were also singled out as problems. In addition, though not mentioned, many people with higher degrees often find themselves in much more menial occupations (due to stiffer competition and, again, rising unemployment), so many who finish uni end up having to go back home (though since Britian is a fairly small country its not uncommon for students to choose to commute and not leave home to begin with). In short, it simply makes more financial sense to postpone moving out as you can focus on saving up for a decent home and wait for the economy to improve before renting or buying one.
