Mom, Dad, 2.4 kids, dog, house in the suburbs. Cat optional.

Basis for most DomCom series. The name references that this is the minimal "core" family unit, a single generation of parents and kids, as opposed to an "extended" family with cohabiting aunts, uncles, cousins and grandparents. Or the fact that it is usually unstable, can cause hair loss, has a fifty-fifty chance of a spontaneous split, and may also lead to early death; either works. Generally avoided in dramas, as [[ParentalAbandonment missing parents]] are a good source of teen angst.

Compare and contrast TheClan, ABoyAGirlAndABabyFamily, BigScrewedUpFamily.

* See ''Anime/MyNeighborsTheYamadas'' for the Japanese version.

[[folder:Comic Books]]
* In the DCU comic ''BatmanAndTheOutsiders'' (first run), there was a group of robot super-villain terrorists called the Nuclear Family. They were based on an idealized 1950's sitcom family and had radiation-based powers. They were eventually blown up.
** They then got rebuilt for the much-maligned ''Battle For Bludhaven''.

* In ''ThePhantomTollbooth'', the main character visits Digitopolis, the land of numbers, and tries to find a way to Infinity. After giving up, he encounters half a boy, cut right down the middle (the other half just ''not there''). Turns out he's the .58 child in 2.58 children for the average family -- luckily the average went up a bit, because it was painful being only .47. Fortunately, the average family also has 1.3 automobiles, and since he's the only one who can drive three-tenths of a car, he gets to use it all the time.
* ''Literature/ProjectNRI": Yamagi Noriko's family is composed of her mother, her father, herself and her little brother Haseo.

[[folder:Live Action TV]]
* ''Series/EverybodyLovesRaymond''
* ''Series/EightSimpleRules''
* ''Series/TwoPointFourChildren''; they named the series after it.
* ''TheGeorgeLopezShow''
* ''Series/TheAddamsFamily'' is an inversion of the Nuclear Family.

* The "Loving Family" ''Franchise/MyLittlePony'' toys consisted of a mare, a stallion, a filly, and a colt.

[[folder:Western Animation]]
* ''WesternAnimation/TheSimpsons''. [[TheNineties Early on]], it even used "America's Most Nuclear Family" as a TagLine.
* ''WesternAnimation/SouthPark'': all of the kids except for Cartman follow this trope to the T.
* ''WesternAnimation/FamilyGuy''
* The evil supervillain "Brainchild" (a.k.a Charles) from ''WesternAnimation/TheTick'''s animated series is the older son in a nuclear family. His parents are very progressive and hope he'll eventually grow out of the "supervillain" phase.
* The Morgendorrfers in ''WesternAnimation/{{Daria}}'' are a parody, although they do genuinely seem to care for each other. Even if the mother is a hopeless {{Workaholic}}, the father a CloudCuckoolander, the eldest daughter a misanthopic SnarkKnight, and the youngest a boy-crazy, popularity-obsessed PrettyFreeloader.


If you want to break out of the 2-or-3-kids pattern, you could try going much, much larger. This can be justified via religious beliefs [[note]]Catholics and Mormons are just two of the groups whose beliefs promote large families[[/note]], but it doesn't have to be. However, if the big family is not the ''main'' family for the story, it's almost certainly a religious reason -- and almost certainly, most or all of the kids are treated as a unit, not as individuals. They may even dress and look identical except for age and gender.

* ''TheSoundOfMusic'' fits the large family motif.
* The BobHope film the ''The Seven Little Foys'', a VeryLooselyBasedOnATrueStory comedy about an immature, absentee father (legendary vaudeville performer Eddie Foy) forced to become a real parent after [[MissingMom the death of his wife.]]

* ''CheaperByTheDozen'' (the book, movie version, and modern remake) has 12. In the original movie there's a scene where a representative from Planned Parenthood arrives to ask the mother (who's apparently well known as having her household in order) to head the local chapter... and upon meeting the kids at first thinks it's a boarding school and then gasps in horror, "Why -- they're all ''yours!''"
* Teresa Bloomingdale's comedy novel ''I Should Have Seen It Coming When the Rabbit Died'' is an autobiography about a strongly Catholic family with some 10 kids.
* The Weasleys from ''Literature/HarryPotter''. Six boys and one girl.

[[folder:Live Action TV]]
* The main family in ''Just the Ten of Us'', spinoff from ''GrowingPains''. As [[HaveAGayOldTime Bo--]] er, ''Richard'' Stabone noted upon seeing the Lubbock family, "They're Catholic!"
* Ma and Pa Kettle, stars of a popular franchise of late '40s/early '50s comedies, were a rural farm couple with 15 children. A running gag would have Ma forgetting a kid's name.
* On the RealityShow ''Series/NineteenKidsAndCounting'', the Duggar family has 19 kids. There also is a SpinOff about their friends the Bates, who have 21 kids.

[[folder:Western Animation]]
* In ''TheWeekenders'', Lor is the sole girl in a family with 12 boys, all of whom are treated as a unit. Her family environment has formed much of the core of her personality.
* Taken to perhaps its ultimate extreme with Cletus Spuckler, ''WesternAnimation/TheSimpsons''' resident "slack jawed yokel". He and his wife Brandine are the parents of some 44 children.[[/folder]]

You may also choose to have a gaggle-o'-kids by using a blended family. The parents' exes are even more optional than the cat.

* ''YoursMineAndOurs''[[/folder]]

[[folder:Live Action TV]]
* ''TheBradyBunch'', bringing together a father with three boys and a mother with three girls.
* ''StepByStep''
* ''LifeWithDerek''
* ''DrakeAndJosh''[[/folder]]

[[folder:Western Animation]]
* ''PhineasAndFerb,'' where the family is [[HappilyAdopted so blended]] it can be hard for a casual viewer to notice it at all. This is helped by Ferb, who has a British accent, hardly ever speaking.
* ''{{Rugrats}}'' began with Chuckie being raised by a single father, but in the second movie Chas remarries a woman named Kira who has a daughter named Kimi. [[/folder]]

Then again, you could go for moderation:

* ''All-of-a-Kind Family'' details a depression-era Jewish family with 5 girls spaced two years apart, and, by the end of the first book, a new baby brother.[[/folder]]

[[folder:Live Action TV]]
* ''MalcolmInTheMiddle'' has a core group of three boys, plus older brother Francis (away at military camp, and later starting his own family) and baby brother Jamie.[[/folder]]

Or you could stick by the nuclear family, but have the extended family get way more involved than is typical. Instead of a grandparent or two and the occasional uncle or unruly cousin, try adding two to three siblings on each side and two to three kids per sibling (with the childless sibling constantly asked when he or she is going to start a family). Pretty soon you have the kind of setup needed for ''Film/MyBigFatGreekWedding''.

[[folder:Anime and Manga]]
* SummerWars features the exploits of an extended family (and one love interest) over the course of a few days trying to stop a viral social networking disaster from causing IRL mayhem.[[/folder]]
* In ''{{PS238}}'', The Nuclear Family is a superhero team which is also an extended family. Despite their "Nuclear" moniker their power set varies from GadgeteerGenius to at least one FlyingBrick. Student Susie Fusion is the child of one of its members, [[spoiler:and Julie Fincher ("84") is the daughter of a [[{{Muggles}} non-superpowered offshoot]], who doesn't get along well with his superpowered cousins.]][[/folder]]

* The ''StarWarsExpandedUniverse'' uses the extended family trope quite a bit. In [=NJO=], you might even think Luke and Mara were the Solo kids' parents.[[/folder]]

[[folder:Real Life]]
* The Western nuclear family is a relatively recent innovation, the product of social and physical mobility brought about by the Enlightenment and Industrial Revolution.
* In more traditional societies, like some in Latin America, the Mediterranean, and South/Southeast Asia, this is ubiquitous. Extended family are almost universally considered close family in those cultures. In many of these areas, extended family either lives under one roof or near one another. The Arab Gulf states, for example, are notorious for having cases of three or four generations living under one roof, with ''all'' of a particular patriarch's (very fertile) descendants living in a single building. In profound cases (e.g., Italy), "family" might include TrueCompanions, or [[TwentyFourHourPartyPeople casual acquaintances.]]
** Weddings are an issue in these cultures. The minimum size for an Indian or Middle Eastern wedding is somewhere in the triple digits; anything smaller and you will run the risk of offending many people. If you live far away from most of your relatives, they will insist that it be held close to them. This goes double if you live abroad—they ''will'' have you get married in TheOldCountry, and that is final.
