What happens when NotAllowedToGrowUp affects an entire ''setting''. This is where an entire area, often an [[AdventureTowns Adventure Town]], is entirely populated and governed by children.

They might actually be children, or they might actually be ReallySevenHundredYearsOld, but they will always at least ''look'' like little kids.

The trope name, which comes from the name of the MagicalLand in J.M. Barrie's ''Literature/PeterPan'', is something of a misnomer, since being in Neverland didn't actually stop anyone from growing older, though it works that way in many adaptations.

SisterTrope to LadyLand, where most of the inhabitants are adults, just monogender.

Not to be confused with the game developer {{Creator/Neverland}}.



[[folder: Literature ]]

* Cittagazze in ''Literature/HisDarkMaterials''. The Spectres suck the soul out of anyone who has hit puberty.
* In ''Literature/{{Everlost}}'' by NealShusterman, the titular Everlost is populated by ghost children who are ReallySevenHundredYearsOld. One of the oldest-looking children was fifteen at the time of death.
* In ''Literature/AWorldOutOfTime'' by Creator/LarryNiven, the protagonist ends up (via a combination of suspended animation and time dilation) on a distant future Earth ruled by immortal, unaging children, the result of an immortality treatment that only worked on the prepubescent.


[[folder: Live Action TV ]]

* The RealityShow ''Series/KidNation'' was based off this trope.
* The ''Series/{{Star Trek|The Original Series}}'' episode [[Recap/StarTrekS1E8Miri "Miri"]] contains a fairly dark example: A planet of [[ReallySevenHundredYearsOld long-lived, unaging]] children who sicken and die upon reaching long-delayed adolescence.
** The same principle was the basis for the New Zealand AfterTheEnd kids drama ''Series/TheTribe''
* The ''Series/StargateAtlantis'' episode [[Recap/StargateAtlantisS01E06ChildhoodsEnd "Childhood's End"]] features a set of villages populated entirely by children (and young adults) because they commit ritual suicide upon turning 24. This is revealed to be the result of an Ancient setting up a forcefield on the planet to protect them from the Wraith, but because the shield was only so big they turned to PopulationControl.
* Naturally, Creator/{{Syfy}}'s miniseries ''Series/{{Neverland}}'', which serves as an OriginStory for Peter Pan, and "[[{{Technobabble}} explains]]" that no one ages in Neverland because it's on a planet in the center of the universe, so time stands still for anyone there.


[[folder: Video Games ]]

* The Kokiri Forest area in ''VideoGame/TheLegendOfZeldaOcarinaOfTime''.
** Interestingly, it's never revealed whether the reason is that the Kokiri themselves are immortal, if it comes from all the [[OurFairiesAreDifferent fairies that congregate there]], or if it's because of the mysterious protection of the Deku Tree (the implication in the sequel ''[[VideoGame/TheLegendOfZeldaTheWindWaker Wind Waker]]'' is that the Kokiri might just be its humanoid ''children'', with a lifespan comparable to its own)
* Youngtown in ''VideoGame/{{MOTHER|1}}'', due to AlienAbduction of all of the [[OnlyFatalToAdults adults]].
* Little Lamplight in ''VideoGame/{{Fallout 3}}'' has been populated entirely by children for nearly two hundred years. It's not clear how they replenish their population, but citizens are banished to Big Town on their eighteenth birthdays.


[[folder: Web Comics ]]

* ''Webcomic/TalesOfTheQuestor'' features this with the [[OurElvesAreDifferent elves]] - due to a goof by a now-reviled elven king (who wanted his people to be able not to die of old age and apparently went to a LiteralGenie for his wish) elves are perpetually young - but not long-lived. They only live to about twenty or so, and then die of 'old age'. The result is that most of the elven territories are inhabited by half-wild children. To make things even worse, it's implied that, as a result, their civilization has gone from being able to match the humans or even the [[TheFairFolk Sidhe]] to something out of ''Lord of the Flies''. Half-elves, although longer-lived, still have much briefer lifespans than humans or Raccoonan - they only get anywhere from ten to twenty years more. There is allegedly an artifact out there somewhere that can fix the problem, but it's missing so it looks like our hero Quentyn has another item to keep an eye out for in his grand quest.


[[folder: Western Animation ]]

* ''WesternAnimation/CodenameKidsNextDoor'': During a ChaseScene, Number 1 crashes and wakes up on a {{Utopia}}n island inhabited entirely by children. He soon learns he's actually inside a LotusEaterMachine.
