Children Are Innocent (Usually.) Children Are Special. Children make us smile and make us laugh. As adults grow older, Think of the Children! becomes a primary motivator for many things they do, because kids are how they Fling a Light into the Future.
Perhaps there was a Sterility Plague, Gendercide, or Herod got a little overzealous; or maybe they were all rounded up to power the phlebotinum generator. At any rate, life is now grey, dreary and pointless, since there's nobody to build a future for.
On the idealistic end of the scale, it can be a temporary case of mass kidnapping, requiring nothing more than a few Big Damn Heroes to get them back. But if the poor things are dead or breeding has simply been closed off as an option, you've fallen off the cynical end straight into New Crapsack, Halfemptia. Expect a rise in Straw Nihilists, possibly spiraling into Bomb-Throwing Anarchists and Terrorists Without a Cause. The Fundamentalist is likely to decide this is some sort of divine retribution, and will be happy to explain why. The Anti-Nihilist may try to find some reason to go on, but he's facing a serious uphill battle.
Any resident Child Haters will probably be pretty cheerful, though.
For the inverse of this trope, see Teenage Wasteland.
NOTE: Do not confuse with Hide Your Children, where a Video Game shows no children to prevent the player from running around murdering them. The game must explicitly spell out that all kids are dead or missing to qualify.
- ICE. All men died out, and Homosexual Reproduction hasn't been invented, so the now all-female humanity is dying out, too.
- In Sunday Without God, when people stopped being able to die, they also stopped being able to give birth, so with no new children being born in fifteen years the world's population has shrunk considerably. The only exceptions are twelve-year-old Ai, whose very birth is shrouded in mystery, and Ulla's twin sister Celica, who was born fifteen years ago but because she was frozen in time, is still a baby.
- The Pied Piper of Hamelin punishes the town for refusing to pay him by leading all their children away.
- Raptors: Don Miguel, a very ancient and very evil vampire, has been devouring children so regularly that the streets of New York City are pretty much devoid of them.
- The Justice League/Young Justice storyline "World Without Grown-Ups" was, as the title suggests, a world without grown-ups along with a mirror-world without kids. It served as an Eigen Plot for Captain Marvel who could shuttle between the two being a biological adult in superpowered form and a kid in his normal one.
- Whether Baravada in With Strings Attached is a utopia or a dystopia is debatable, but it certainly is nearly childless. Only two children are seen by the four while they're there, and one of them is actually As'taris's mother Brox, reborn as a five-year-old boy after she was murdered for her... unique sense of humor.
- The childless problem appears to have been solved in The Keys Stand Alone after the G'heddi'onians replace the tirin; there are plenty of kids around. However, one of the Geddies tells the four that the Baravadans (now known as the Natives) are still not having children. At one point John speculates that too much magic makes people sterile, which would be why in With Strings Attached magic was forbidden in Ketafa.
- Notably averted in the Mad Max franchise. Every film in the series has children involved. Excluding Max's daughter, children are more prominent in Mad Max: Beyond Thunderdome and Mad Max: Fury Road.
- In Children of Men, almost all of humanity has been rendered sterile, and society has collapsed into violent chaos.
- The movie Daybreakers strongly implies this for most of the population, as the vampires, who compose 95% of the population, do not age or procreate. Another 4% are humans kept as stock to produce blood to feed the other 95%. The other 1% may have kids, but they are hunted down relentlessly by the vampires (who need more blood).
- Chitty Chitty Bang Bang features a Ruritania in which the Child Hater rulers have actually outlawed children. Yes, it makes no sense. It's not clear what the government does to the children, except that they're rounded up by the infamous "Child Catcher".
- In Indiana Jones and the Temple of Doom, Indiana and his companions end up in an Indian village that had been raided by members of a Thugee cult who had stolen a sacred relic and all the children.
- In Freddy's Dead: The Final Nightmare, Freddy Krueger has managed to kill all the children (sans one) of Springwood, and now seeks to break out of the place to do it everywhere else.
- The 1992 novel Children of Men by P.D. James.
- Greybeard, by Brian W. Aldiss, has a childless world caused by a Sterility Plague.note
- Early in Belgarath the Sorcerer, Belgarath encounters a camp populated entirely by old people. They turn out to be the people who refused to follow Gorim to Ulgo, and were cursed with sterility as a result. They're just waiting to die off, and Belgarath finds the winter he spent with them very depressing.
- New World in the Chaos Walking trilogy. Due to the fact that all the women in Prentisstown are dead, there hasn't been a child there in 13 years - not since the main character Todd was born.
- In Peter S. Beagle's The Last Unicorn, a town has stopped having children ever since they heard a prophecy that one would bring down the king and end their prosperity. They live in dread of that day. At the end, after the old king has been brought down, the magician Schmendrick urges them to have children — it might help.
- The Declaration Trilogy by Gemma Malley is set in a world where scientists have discovered life-extending drugs. However, a corrupt government is using the drugs to cling to power and prevent a younger generation from challenging them. Under the pretext of preventing overpopulation, strict laws have been passed, stating that no-one may reproduce unless they "Opt Out" of taking the drugs; even then, they are restricted to one child each. Any children born to parents who have not "Opted Out" (or who have "Opted Out" but already have a child) are labelled "Surpluses" and are taken away from their families to be raised in grim institutions. As very few people choose to "Opt Out", the result is a society where children, whether they were born legally or not, are greatly mistrusted.
- Ashes by Ilsa J. Bick has more of a "Teenager-less Dystopia". In this apocalyptic world, some sort of electromagnetic pulse turned most of the teens into zombies and killed most adults. As a result, most of the survivors are the elderly or children under 12.
- In The Handmaid's Tale by Margaret Atwood, future Earth is so irradiated that most humans are sterile, and the births that do happen are usually "Un-Babies" with severe defects. This leads to a theocracy in which the few remaining fertile women become sex slaves for powerful men.
- Used to rare positive effect in the Erich Kästner novel Die Konferenz der Tiere ("The Animals' Conference") and the 1969 animated movie based on it, in which the animals decide that after entirely too many of the humans' peace talks and conferences have come to naught it's time for them to do something about it. After multiple appeals to reason and creative attempts at sabotage have failed to convince the stubborn humans to abolish war, the animals resort to taking the humans' (cooperative) children away from their "clearly unsuitable" parents by "abducting" them and hiding them in places where they can play safely with the animals looking after them — and that finally does the trick.
- In A Song of Ice and Fire, the city of Asshai has no children. The reason for this is not given, but since Asshai is a place where the darkest of magics are practiced the implications are quite sinister.
- In Stargate SG-1, the Aschen Confederation offered the people of the planet Volia (P3A-194) a cure for a terrible disease on their world. However, the vaccine also resulted in sterility. A once thriving world of millions was reduced to chaos and riots, and then to a peaceful but empty world, with a few thousand apathetic residents and automated machines tending farmland. An earlier episode portrayed a Bad Future in which the same race was in the process of doing this to Earth.
- In "Past and Present", SG1 arrives on a world where everyone is a young adult with amnesia and, while there are pictures of older people and children, they are nowhere to be found. It turns out that a Mad Scientist's experiments with longevity caused everyone to revert to a younger age, making the elders young adults and the children nonexistent.
- The main driver for The Outer Limits (1995) episode "Dark Rain". In the episode, a rain of some toxin causes people to become mostly sterile, resulting in this.
- The third season of Zoo deals with the world facing global sterility, as elementary schools are shut down all over the world.
- The Handmaid's Tale, like the novel it's based on, takes place in a theocracy that began after the birthrate went down and the babies that were born had birth defects. The show has a flashback depicting June/Offred at the hospital with her child, looking at an empty nursery. A nurse explains to June that the only babies born at that hospital either went to the ICU or died. Later, someone actually attempts to kidnap June's baby.
- Dungeons & Dragons supplement Heroes of Horror (which focuses on adding horror elements to a D&D session) has a chart of random creepy elements. One of them is "After spending some time in a village, it dawns on the heroes that there are absolutely no children."
- At the beginning of Half-Life 2, the Combine have been using a suppression field to arrest human reproduction for years. The empty playground pictured above has the faint, ghostly laughter of children to reinforce the creepy-factor. Blowing up their Evil Tower of Ominousness at the end of the game removes the suppression field.
- Resident Evil 4 has the village of people who've been turned into People Puppet mooks, and notes explain that the children were unable to survive being implanted with a Puppeteer Parasite. Looking at the bonfire in the village near the start of the game reveals some very small skeletons.
- The Walking Dead has the community of Crawford, which exiles or kills anyone that is under the age of 14, requires special care (diabetes, long-term illnesses), or elderly. This bit them in the ass harshly, when one woman didn't want to abort her baby and went on a rampage against the community. By the time you arrive there, it's overrun with zombies, having clearly collapsed from within.
- Resident Evil 5 continues this trend where natives are given "vaccines" to protect against a "disease", with said vaccines actually being experimental Las Plagas and the deaths of all children, women, and most men being blamed on the alleged disease.
- Vault City in Fallout 2 has no children due to contaminated groundwater rendering the population infertile. The fact that the place is a distopia is unrelated, though: that's because the city's citizens are stuck-up snobs who look down their noses at anyone not from a Vault and the oppressive First Citizen has passed numerous laws that prevent too much contact with the outside world, resulting in cultural and economic stagnation. Whether either situation improves is up to the decisions of the Chosen One.
- Fallout 3's DLC The Pitt is affected by a contagion that disfigures and sterilizes the residents, or worse, makes them go crazy or become Trogs. The only child in the area is Marie, the infant daughter of Lord Ashur, and she has an immunity to the TDC (Troglodyte Degeneration Contagion) that raises hopes for an eventual cure.
- It's not completely childless - one in a thousand survive - but this is pretty much what happened to Tuchanka in the Mass Effect games when the genophage was deployed, and the krogan culture has spent the last 1500 years spiraling below the Despair Event Horizon as a result. It's telling that one of the Golden Ending slides for the krogan, if you cure the genophage, depicts them with children again; it is the happiest you will ever see them.
- Notably, Krogan reproduction is so fruitful that this situation is easily avoidable; even 1 in 1000 is still more than enough to allow for positive population growth. The sticking points are Krogan culture, violent as it is, and the aforementioned despair and aimlessness that has prevented most Krogan from even trying to reproduce.
- This is one of the reasons the krogan Clan Nakmor was chosen to join the Andromeda Initiative, as they, apparently, exhibit a measure of resistance to the genophage. Naturally, the salarians see it as a mistake to allow the krogan to uncontrollably populate the Andromeda Galaxy.
- Overall, the situation of the Krogans actually came from an inversion of this at first, but turned around and ended up played straight, dating back to before they were introduced to the galactic community: The Krogans were an entire race of Blood Knights and warrior-berserkers who pretty much built their entire society up around the concept of who was the toughest guy on the block and who could fight the best fights. As a result, they evolved into a race of 800-pound bipedal lizard men with redundant organs and a penchant for waging war on themselves. To keep up with this, they also evolved to have an absolutely staggering birthrate that would put rabbits to shame, which served them quite well since their death rate was also comparatively high. The problem emerged when the Salarians, looking for a weapon to use against a race of hive-minded space insects called the Rachni that the galaxy was currently at war with, uplifted the Krogan to serve as those weapons due to their toughness and sheer numbers. They worked well, driving the Rachni to the brink of extinction and winning the war, but the newly uplifted and unified Krogan now faced the problem of no longer having a war to fight to keep their numbers (and aggression) in check, so they started a bit of a campaign of their own to "colonize" (and by colonize we mean invade) nearby planets to accommodate their high birthrates in an event called the "Krogan Rebellion." To stop the Krogan, the Salarians introduced the genophage to deprive them of their numbers advantage so that they could be brought under control, and the rebellion was successfully suppressed. As mentioned above, the 1-per-1000 birthrate is still viable on paper, but what it didn't account for is the massive hit to the Krogans' cultural ego that resulted from losing the war, which pretty much killed the unity the Krogan had experienced during the war with the Rachni and caused their society to once again fragment, devolving back into warring clans and wandering brigands and making the birth rate nonviable.
- In Digital Devil Saga this forms a major plotpoint and reveal at the end of the first game giving both the characters and players a major clue that something is seriously off about the Junkyard. The second game averts this trope entirely.
Lupa:Have you ever seen a child here in the Junkyard?
- Wellington Wells, the setting of We Happy Few; There are no children anywhere, and some adults can be seen playing with the playground equipment "Because if we don't, who will?" That's because during an alternate World War II, the Germans occupied the village, and the people had to do a Very Bad Thing— Namely, give away anyone under 13 to the German Military. The guilt eats away at the Wellies so much that they take a Fantastic Drug to forget what they did, but still fly into crazed frenzies when they are reminded. One article you find describes a "Breeder Riot", where an angry mob killed a pregnant woman. Sally Boyle is mother to the only baby in town, and her storyline is trying to escape Wellington Wells before someone discovers it.
- SCP Foundation: SCP-1322 is a rift to Another Dimension whose denizens were briefly friendly to the Foundation, until the Foundation tried to help them by developing a vaccine to a widespread illness. Tragically, it had the side effect of sterilizing the population, and the furious "Last Generation" launched a Lensman Arms Race specifically to get Revenge.
- Zig-zagged in 17776, set 15 000 years after every sapient being spontaneously developed Complete Immortality and became infertile for unknown reasons. For the most part, people feel that Living Forever Is No Big Deal and pass the time in deliberate Modern Stasis with hobbies like increasingly bizarre variants of football. The infertility issue is usually carefully talked around, but one character mentions finding a modern-day mural of children and breaking down in tears.
Ten: It's a free play, buddy. Clock's all zeroes. It's after the end of the world.
- The Easter Bunny Is Coming To Town features the adults-only city called Town, which oddly is ruled over by a child king and his older aunt. There's a subversion involved in that near the Town is the children-only city called Kidville.
- Played With on Young Justice—Klarion and his minions use magic to split the Earth into two dimensions, one containing everyone under 18 and the other with everyone older. From what we see the kid world functions surprisingly well, with teenagers doing all they can to care for unattended children. The adult world, however, breaks into riots from desperate parents whose kids vanished right before their eyes.
- Parodied in American Dad!. When Stan goes to see a doctor about a vasectomy, he finds the clinic's dream is a world without children.
Stan: A world without children... Future generations will thank us!
- A variation occurs in the Phineas and Ferb episode Phineas and Ferb's Quantum Boogaloo. In process of child-proofing everything, eventually children themselves were child-proofed and stored away until adulthood. Under the rule of Emperor Doofenschmirtz, children are not allowed any more.
- Many Native American communities became this in the late 19th and early 20th century, when their children were forcibly removed and sent to government-run residential schools under the "kill the Indian, save the man" assimilation policy. Thousands died (mainly from disease), and those who survived returned to their families scarred from abuse and stripped of their language and culture. The impact of this policy (which in some places didn't end until the late 1990s) is still felt in Native American communities to this day.
- Rural areas around the developed world can shade into this as fertility rates drop and emigration to the nearby cities occurs, leaving increasingly elderly populations behind.
- Many nations and ethnicities have seen their populations drop below replacement level reproduction and begun population declines. Some countries have encouraged or relied upon immigration to make up the difference, to varying levels of acceptance by the native born. Though mathematically the declines have terminal points, how low they will actually go is anyone's guess, since a turnaround is a simple matter of population members being willing to have more children. As an example, Japan's current rate will drop its population from 128 million in 2010 to 87 million in 2060.
