"Luke has never been to school. He's never had a birthday party, or gone to a friend's house for an overnight. In fact, Luke has never had a friend. Luke is one of the shadow children, a third child forbidden by the Population Police."To try to solve an overpopulation problem, governments may limit the total number of children a person or couple can have. There are a number of variations on this. Sometimes every couple is allowed a fixed number (frequently two); other times, the number allowed is tradable, luck-based, or determined by some kind of eugenic principle (parenting skills are less commonly judged). Enforcement methods may range from punitive taxes on extra children, through mandated birth control and sterilization upon the birth of the last child allowed, to outright killing of excess population. These dystopias always seem to assume stable long term marriages, they usually offer some number of children per couple. Second marriages are ignored. Only very rarely does it actually work. Often it signals a descent into dystopia. It's also very common for the protagonist to be a child who exceeds the population cap. Or it can work too well, ending up with a Childless Dystopia. This trope is most common in literary science fiction from the '60s and '70s; it died out as a trope because while it had its heyday in fiction, the post-World War II Baby Boom came to an end as living standards and opportunities for women in North America and Western Europe expanded and people chose to have fewer children starting later in life. Since then, the pattern has held and spread to other parts of the world, largely making this a Dead Horse Trope. Because population growth is considered by some to be a problem in Real Life, fictional Population Control is seldom directed toward encouraging or mandating births, either among some groups or the entire population. Inversions occasionally do crop up in works in which a Depopulation Bomb, Robot War, mass infertility or other threat has made humans an Endangered Species. The entries on this page mainly concern keeping the population down by preventing pregnancies (through birth control or sterilization) or preventing illegal children (through abortion or infanticide). In some works of fiction, the government attempts to prevent pregnancies and control the population through banning sex or promoting/enforcing homosexuality. In some cases population laws are repealed or at least slackened when the capacity for interstellar colonization is achieved. See Also: Kill the Poor, for one instance where this trope is selectively applied, and Darwin Awards, for accidentally self-inflicted examples.

open/close all folders
Anime and Manga
- In Scrapped Princess, the entire world is allowed to have only so many human residents; when the population gets too big, the excesses are killed off by the Peacemakers.
- A major theme in Tengen Toppa Gurren Lagann, where this is practiced in villages, planets and entire universes.
- Inverted in Gundam SEED where the Coordinators' society—whose population was steadily reducing—in the space colonies actually mandated Arranged Marriage in the hopes of increasing birth rates. It didn't work.
- In Attack on Titan, when a third of humanity's territory is overtaken by the titular giants, a fifth of the population— mostly refugees from the lost territory— is hastily conscripted for a suicidal counterattack. While the best-case scenario is obviously for the attack to succeed and the territory be retaken, the government barely even tries to conceal that the true objective is to reduce the population to free up food and resources for those that remain. It does not succeed, and the attack force is lost nearly to a man.
- DNA2 has an extreme example, the future has a problem with overpopulance and a strict law was enforced that allows people to only have one child. Men who father more than one child get the death penalty. When they found out that a mega playboy of the name of Junta Momonari had fathered 100 children and had left behind mostly male descendants with the same potent DNA, he had already been dead for quite some time. They decide that instead of altering the DNA of those descendants, it'd be much easier to just go back in time and alter Junta's DNA before he becames a playboy and fathers any children. Which starts up the plot.
- Inverted in Transformers: More than Meets the Eye: Transformers are born by the planet releasing pulses which settle and create life by coding energy in a spark, which is placed in a body to make a new Transformer. The pulses began to decline (and in other continuities, like Regeneration-1 the race goes extinct) so the then leader, Nova Prime, commissioned life to be drawn from his matrix as he needed to expand the population though his other motive was to make their race great so they could colonize beyond their world.
- The movie Fortress (with Highlander star Christopher Lambert) has the protagonist and his pregnant wife try to leave a dystopian US after it implements a one-child policy to fight increasing population growth.
- Child Reduction Act. Families with more than one child must either pay a tax on the extras or send them to concentration camps.
- Z.P.G.. All parents are forbidden from having children for one generation (30 years). The penalty for violation is death.
- The Last Child. Each U.S. couple is only allowed to have one child. If the first child dies they can't have another.
- Mentioned in the opening expository voice-over in A.I.: Artificial Intelligence, as well as the Brian Aldiss short story it was based on, "Super-Toys Last All Summer Long", as a response to the polar ice-caps melting and flooding the coastlines.
- In Paul Verhoeven's adaptation of Starship Troopers, one of the female infantry recruits says that she joined because she wants to have babies, and it's easier to get a license if you're a citizen.
- Inverted in Robot Jox which has the government using propaganda to encourage pregnancy after most of the world was devastated by World War III.
- In Supernova, despite the fact that there are multiple colonized planets, on a spaceship each individual has to apply for a license to have children. Their problems start when the guy is given a license but the girl isn't, meaning they can't have a child together.
- Notably averted in Soylent Green. That lack of any sort of population control at all is exactly the reason why it's such a Crapsack World to begin with.
- In Clive Barker's The Plague, having ANY children is declared illegal worldwide, as a mysterious ailment has caused all children under the age of nine (unborn babies included) to fall into a coma. Until a cure can be found, producing more comatose infants will only exhaust the resources already strained by the need to care for so many inert children.
- In In Time, society has been rendered ageless, but to counteract the inevitable population explosion, every living person has a clock which holds their exact amount of time left to live. People can earn more time through various means, but once they hit zero they die instantly. The system is skewed to place the burden on the poorest part of the population.
- Stand on Zanzibar by John Brunner has eugenically-based population control, with incredibly strict genetic screening requirements (e.g., people who carry color-blindness genes or genes correlated with schizophrenia are not allowed to have children). The title comes from the idea that, if you gave everybody on Earth something like two or three square feet, at the time of the story's start, they would just fit onto the island of Zanzibar. Even with the above, by the story's end, humanity would be well into the waters off Zanzibar...
- In the Known Space series by Larry Niven on Earth the number of children you can have is based on several factors: you can be assigned children based on a fixed metric, buy licenses for extra children, or even win them in a lottery (this last is the result of alien influence by a species that's attempting to breed psychic luck powers into humanity). At one point there are even legalized gladiatorial death duels for birthrights, winner take all. The ARM police go on "mother hunts" for those who illegally went over their reproductive limits, and very rare individuals are awarded an unlimited breeding license— their genes are declared to be so useful that humanity needs them more than it needs the room and resources freed up by not having them. Notably Carlos Wu's genius and fitness gives him an unlimited birthright, while Beowulf Shaeffer's albinoism revoked his birthrights. So Carlos fathered Beowulf's son Louis Wu. However, by Ringworld only the lottery remains due to corruption in the boards, so all of Louis's children are Lucky. Presumably they'd also run out of health-impairing genetic traits to select against by that point.
- Also humanity's colony worlds lack population control of any kind. Eventually Beowulf found a planet that was close enough to Earth that it wouldn't set off his wife's phobia of non-Earth environments and they had more children there.
- In another Niven verse, A World Out Of Time, the State has become a One World Order where Individuality Is Illegal, and only massive fusion-powered desalinators on every shoreline can provide enough fresh water for the massive population. A few generations back, the State instituted compulsory sterilization for all those with harmful genes, both for eugenic reasons, to save money on heath care, and to slow the rapid population growth. No wonder they're so desperate to Terraform.
- Enders Game has a two-child limit enforced by punitive taxation. However, because Earth is governed by a somewhat weak version of The Federation, certain individual jurisdictions, particularly predominantly-Catholic ones, seem to have lax enforcement policies. Ender is a state-sponsored exception as his parents were supposed to breed a fleet-commanding prodigy and his older siblings turned out to be a sociopath and a pacifist.
- Ender still took a lot of crap in school because of his Third status and, of course, no child would explain why being a Third is bad. Then again, when did kids (especially bullies) need a reason to be cruel?
- It is hinted in the "Shadow" spinoff series that the population laws were actually a Zero-Approval Gambit designed to be so unpopular as to hasten the dissolution of The Federation after the war so that humanity would not be controlled by a single monolithic government that could be corrupted.
- In Green Mars, one character proposes to fight overpopulation by giving everyone the tradable birthright to three-quarters of a child. (That is, each couple has the right to 1.5 children; they can then buy or sell half-children to get the number they want and can afford.) This doesn't ever get implemented, though.
- Robert A. Heinlein has a few examples:
- I Will Fear No Evil has population control — each person gets licensed for a set number of children when he/she turns eighteen. Eunice mentions at one point her marriage is considered a "second class contract", since she's licensed for children and her husband is not, implying that if he were, their marriage would be in a different category.
- It also appears in Time For The Stars. Each family can have three children. Extra children are taxed and the family doesn't receive government financial help for them. Families can trade for each other's unused child slots or apply for reclassification for more children.
- In Podkayne Of Mars Marsmen apply to the 'Population, Ecology and Genetics' Board to be 'pegged' at a preset number of children, probably because of the necessity of not exceeding the support potential of the semi-terraformed colony. However none of the mentioned families seem to have any trouble getting the number they want. Podkayne's parents are in fact offered seven children but her mother prefers five as 'all she has time for'.
- The end of Methuselah's Children mentions that earth now has such an overpopulation problem that you need a license to have kids. Which is why earth needs Andy Libby's FTL drive.
- One of Lazarus Long's stories in Time Enough for Love brings up a time that Earth tried declaring everyone over 80 to be legally dead, this being a couple centuries after they invented rejuvenation, one of Lazarus's sons tries emigrating a bunch of those elderly refugees to a new colony world. And one mentioned symptom of Secundus's decay, two thousand years after colonization, is that they've instituted birth quotas.
- The Shadow Children Sequence by Margaret Haddix is a series about a world where families can only have 2 children (the main character is, of course, a secret third child). Rich people are allowed to cheat, and the Population Police are utterly corrupt.
- Lisa Mason's future in her book Summer of Love has a lottery for who can and cannot have children, but include the concept of "skip-children", where frustrated parents can put their combined DNA in a bank to be born decades or centuries later, to be raised by a descendant.
- In The Andalite Chronicles, it is mentioned that the Andalites used to have population control laws, but that they were repealed because of the war.
- Carnival by Elizabeth Bear has an AI that determines the maximum stable population of Earth and selects people to be killed whenever it is exceeded.
- Lois McMaster Bujold's Vorkosigan Saga has many different planets, using different methods:
- Uterine Replicator technology is widely used on many planets, as it allows for having children without the inherent risks of pregnancy. Combined with genetic testing and embryo selection this also serves to ensure the birth of healthy, defect-free children or on some planets even Designer Babies.
- Barrayar is underpopulated, and has unfettered reproduction (though it is somewhat "backward" and considers all sex out of wedlock to be illicit). During the Time of Isolation however, the Barrayarans practiced infanticide of any child possessed of obvious defects or mutations, as they lacked the medical resources to care for any disabled individuals.
- Beta Colony is a marginally habitable world, and has strict population control. All babies must be licensed, though getting a baby license seems to be about as difficult as getting a driver's license (at least for the first two.) Since contraceptives are legally required for all females (and hermaphrodites), all sex between consenting individuals is considered to be normal recreational behaviour, though they do have statutory rape laws.
- Athos is underpopulated, but since its entire population is male, it requires Uterine Replicators for anyone to reproduce. The actual cost of raising children to the age where they are self sufficient is a major part of the planetary government budget, unlike most other planets where it is part of the informal economy. There is a credit system where men earn the right to father children through voluntary civil service. As Athos is gradually terraformed, the population is slowly being allowed to grow, with new reproduction centers getting built as appropriate.
- The Cetagandan Empire is a group of planets exercising extreme bio-engineering, where every child "born" (at least among the Haut class) has its genetic makeup designed by the central government. What is more, it would be possible for the child's parents never to have even met, let alone had sex.
- Fred Saberhagen wrote a Twenty Minutes into the Future book like this: Stripperific clothing and casual sex are societal norms but couples are limited to two offspring, with severe penalties for violations.
- Anne McCaffrey's Pegasus in Flight has limited children laws; theoretically, each woman is permitted two children (however, the rules can be bent by people with influence, such as the Center). The first protagonist is an example of an illegal extra child, who was retroactively legalized in exchange for services rendered to Law Enforcement and Order. It also has a plot with a child smuggling ring. These laws are enforced by having the extra children (And any women caught producing them) sterilized. These laws have apparently been repealed in the sequel series, as multiple characters are shown having more than two children without any difficulty, presumably because practical interstellar travel has solved the crowding/resource issues that made the population control laws necessary in the first place.
- In The Giver, every family unit is allowed two children. If a child dies, the parents either can apply or are simply given another baby of the same gender and same name as a replacement. However, they come from Birthmothers, which only have 3 children, then a lifetime of hard labor. Even then, only 50 newbabes are given to parent units in December.
- In 2061 by Arthur C. Clarke it's explained that the one-child policy of China was eventually replaced by one where a person can have two children for free but any additional children cost a prohibitively-expensive fee which doubled with every additional child; one character, Sir Lawrence Tsung, is a multimillionaire who was able to afford to have ten children (his ninth child, William Tsung, has a shuttle craft named after him).
- In the CoDominium universe, Earth is so overcrowded the government is slipping contraceptive drugs into the
ProlesCitizens' food supplies and releasing infertility viruses into the ghetto/reservation-like Welfare Islands. Only those who move to frontier planets can have larger families.
- In David Brin's Uplift universe, all reproduction has to be carefully screened, both as population control and as a prerequisite to joining the Galactic civilization. Probationers are those who fail— they are permanently sterilized to avoid spreading undesirable genes. Client races have a card-system, colors determine how many kids you can have, and a White Card is an unlimited license— your genes are so good, anyone who wants them can have them.
- A short story 'The Sliced-Crosswise Only-on-Tuesday World' by Philip Jose Farmer, involves a world so overcrowded that it couldn't support more than a seventh of humanity; so Human Popsicle technology was perfected, allowing for each person to be awake only one day out of each week. The story had a Downer Ending, after working hard to get on the same day with a woman he's fallen in love with after seeing her in her cryo-tube, he finds she has worked equally hard to get onto his old shift... Later expanded into the Dayworld series of novels.
- In Larry Niven's and Steven Barnes's Saturn's Race, the world discovered that a vaccine distributed throughout the third world nations twenty years prior had the deliberate side-effect of causing sterility in the children born to the inoculated.
- In The Declaration by Gemma Malley, people who have signed the Declaration are not allowed to have children. That doesn't stop them, though, and the kids end up in Surplus Halls, or worse.
- The Bladerunner (no relation) by Alan Nourse had the government require sterilization as the price of medical treatment. A "bladerunner" was someone who smuggled surgical tools for doctors willing to perform unauthorized medicine (doctors weren't permitted to take medical equipment out of the hospitals).
- A variation of this based on gender is put out in The Dark Elf Trilogy. (See the Forgotten Realms entry below, as these books are the ones that defined those rules.) The main character (who has since become well known) was, incidentally, a third son.
- In Inside Out by Maria V Snyder, the population is divided into two castes, the Uppers and the scrubs. Scrubs are encouraged to have as many children as possible and are denied birth control. Men and children who break the rules are executed, but fertile women who commit infractions become "breeders", kept chained down and constantly pregnant until their bodies give out from the strain. Uppers, on the other hand, are allowed one child per couple. If there's an accident with their birth control, the extra child is dyed to look like the scrubs' ethnicity and given to a scrub foster mother. The overlords use this to foster class division, telling the scrubs that the Uppers are spoiled rotten and telling the Uppers that the scrubs are too lazy and selfish to use birth control despite their overpopulation.
- In Mikhail Akhmanov and Christopher Nicholas Gilmore's novel Captain French, or the Quest for Paradise, all colonies impose birth licensing policies once they reach a certain population density. While there are plenty of dystopian governments, even the nice ones do it. There is a group of women, whom the eponymous space trader nicknames "the Frantic Mothers", whose goal in life seems to be to bear as many children as possible, regardless of who the fathers are. They will do anything to move to a new colony that encourages this sort of behavior, including paying for passage with sex (preferably with a fertile male, for obvious reasons). Since the protagonist had himself sterilized (completely reversible), the Frantic Mothers are a little disappointed in him. Since most humans in this universe undergo a procedure that stops aging, it is possible for the same woman to be the progenitor of several colonies (imagine how many babies she can make in several centuries).
- In The Caves of Steel, Earth licenses couples to have a number of children based on the parents' genes and social contributions. This is presented quite neutrally (Asimov considered overpopulation to be a major threat). Spacer societies are considered less moral, since they combine population control with eugenic breeding programs and mandated late term abortion.
- In the Uglies series, parents are prohibited, and also incapable because of the whole pretty-mind-thing, of having more than one child every ten years. This keeps the pretty parents able to focus on one child, and keeps sibling bonds from forming. It's surprisingly effective.
- In Cyril Kornbluth's horrifying dystopia Shark Ship, the ocean-dwellers have a two-child limit (with officers of the ships forbidden children altogether for fear of nepotism.) It turns out that the land-dwellers implemented a one-child policy, and this, together with their glorification of violence and torture, has effectively provided a solution to the problem of overpopulation. A Final Solution, as it were.
- Robert Westall's dystopia in Futuretrack Five has The Futuretracks: 'jobs' which are designed to help thin out the Unnem populace: most are geared towards a life in which either regular contact with direct violence kills followers, or significant (and artificially increased)risk kills them.
- A stealth example can be found in one of Piers Anthony's early novels (forget which), in which couples are only allowed to have kids if they're of different racial backgrounds. This is ostensibly intended to eliminate racism from the Earth within a generation, but in practice it's a population-control mechanism, as not everyone can find a suitable mate.
- Inverted in Robert Silverberg's The World Inside. In the year 2381, most of Earth's 75 billion people live in three-kilometer-high (9,000 feet) "urban monads", where they start their large families around puberty. One man has four children. It is considered shamefully low, but his wife is infertile due to an accident during surgery. He is considering taking another.
- Poul Anderson is evidently quite fond of this trope:
- In "Time Lag", Vaynamo has stablized its population, voluntarily. This incites anger in the conquerers — Chertkoi is heavily overpopulated. Bors tells Elva that they can't hoard its resources; Elva retorts they should take the consequences of having bred like maggots.
- In "Starfog", when Graydal hears that there are planets where some women do not bear children owing to population control, she immediately concludes that her ship, which they believe can not return home, must stay on the frontier world.
- In "Eutopia", Iason scorns the Westfell reasons: true, they limit their population too, only not because people need space, but because of their greedy desire not to split up their estates — in service of their reified families.
- In "Goat Song", the population control requires exactly as many children born as decreed, to keep human society human. Harper notes that this means the promise to revive them all in the future must be a lie.
- It's revealed in the epilogue that of The Death Cure the disease known as the Flare was initially supposed to be this, but it got out of control.
- F. Paul Wilson's LaNague Confederacy series has this in place on Earth That Used to Be Better, with a uncommon yet obvious complication to the trope; the population control bureau is completely and utterly corrupt. Though it supposedly enforces a "one child per parent" policy, any and all political activism is punished by sterilization under the guise of eliminating hereditary disease. Luckily, this came about after the development of Casual Interstellar Travel, and deviants are given the option to emigrate.
- Rick Griffin's Ten Thousand Miles Up takes place on board a Generation Ship that has maintained a constant population of 10,000 for four hundred years with contraceptive implants and a waiting list to reproduce. Captain Atari and his wife Jakari took themselves off the list, giving up their chance to have kids until they steal a planet and a Terraformer and decide to stop enforcing the list.
- The Neanderthal Parallax: The Neanderthals only have children once ever 10 years. This is accomplished by women and men living separately and only meeting on a cycle that ensures they're only fertile one visit every 10 years. The population control also allows them to concentrate their resources on particular age groups at regular, predictable intervals.
- In "The Machine Stops", humans live their entire adult lives in one-person underground cells in which all their needs are met. The global Machine that provides for them keeps the birth and death rates balanced by mandating encounters for procreative sex - the only time humans actually interact in the flesh - and by approving requests for euthanasia from the elderly, sick, or unhappy.
- In Twig, it's revealed that one of the major future plans of the Academy of Evil is the implementation of universal sterilization that only the Academy can cure, allowing them to selectively control which individuals reproduce by choosing who to give out the cure to. This is only discovered when a disgruntled academy graduate initiates the program early and distributes information on it, resulting in massive popular unrest.
Live Action TV
- seaQuest DSV had an episode with an island nation where street kids were hunted by death squads as a population control measure, which was almost definitely based off the Marcos Government in Real Life.
- On one of the worlds the Sliders visited, the population was kept low by heavy marketing of birth control (billboards advertised "Birth Control Cola"), and by ATMs which dispense free money to anyone willing to enter a lottery in which the winner must commit suicide via poison. "Winners" are treated like royalty until their time comes, and the ones the Sliders met considered it an honor. This was the result of them paying attention to one Reverend Thomas Malthus, who argued that human population growth would always outpace food production. As a result of their ubiquitous reinforcement of birth control, there are only 500 million people in the whole world.
- One group on this world argues that the Lottery is unnecessary. Instead, they advocate better birth control.
- Star Trek: The Original Series has a third season episode, "The Mark of Gideon", where a planet's failure to deal with this led to ridiculously extreme overcrowding (though no problems with health or resources, apparently). The episode first aired in 1969.
- The Last Child was a mediocre TV Movie set in the near future when couples were limited to only one child, even if the child died before puberty.
- In the 22nd century of Terra Nova the protagonist was sentenced to six years in prison for having a third child. Fortunately they don't care about population laws in the virgin frontier of 85 million BC.
- actually, his prison sentence was for punching the cop that grabbed his daughter. the punishment for having a 3rd child is just a hefty fine. additionally, 3rd children were ineligible for many government programs, including the terra nova project itself.
- Inverted on Battlestar Galactica (2003), in which the possibility that couples' reproduction might have to be made mandatory in order to sustain a decimated human species was broached soon after the destruction of the Colonies.
- The Lottery has the government forced to do this, in response to a mysterious interruption to the reproductive ability of the human species. The desis, if it is that, is also putting a control by stopping the population from growing any further.
- On The 100 the Ark has a one-child policy in order to reduce its population and conserve resources. To this same end, it applies the death penalty towards even the most minor crimes, and if resources are becoming truly scarce, the Ark's government is authorized to start "culling" large swaths of the population.
- The Drow families in Forgotten Realms are only allowed two sons at any one time, though they can have as many daughters as they like. They sacrifice the third to Lolth. Unless one of them conveniently dies beforehand. Drizzt Do'Urden was the third child of his family, but one of his brothers was assassinated shortly after his birth, so they didn't have to sacrifice him. This tradition exists because Lolth herself demands it. She has...issues...with men, to put it lightly.
- Inverted in another dark elf example, from the old Role Aids third-party D&D supplement line: In Elves, dark elf society is virtually lawless, except that it's prohibited to kill a female dark elf before she's produced at least two offspring. Backstabbing and feuding would probably wipe out their population if not for this rule.
- Warhammer 40,000:
- For all its dystopianism, this is actually averted by the Imperium of Man, as rampant population increase is the only thing keeping it going, allowing them to win wars by virtue of outnumbering the enemy by several orders of magnitude. It's also how Space Marine Chapters stay at full strength, with the rate of success of recruiting, indoctrinating and surgically modifying humans being so low.
- The Tau use a form of population control, in that all pairings are determined by examining genetic potential and then getting the parents to mate. The offspring will not be raised by the parents but the caste-wide educational system (though parents often take an interest). Tau society functions on Happiness in Slavery and mass mind control, hence the lack of outrage from the Tau.
- In Mindjammer the Core Worlds require a license to reproduce, and before the discovery of Planar Drive Old Earth had mandatory euthanasia at the age of 500.
- In Mass Effect, the Quarian Migrant Fleet has to keep tight control of its population due to the limited resources. Tali mentions that they're currently running a one child policy, but also that the limit changes depending on the population and available resources and that there have even been some periods when the population dropped far enough that positive population control was used.
- The population of the Kaka clan in BlazBlue is kept at 100 by the Applied Phlebotinum that created them. A shortage of males keeps the population count from rising quickly, while parthenogenesis ensures that there will always be at least 100 Kaka.
- The Combine from Half-Life 2 are more thorough and have a no child per family policy, enforced by suppression fields.
- In Schlock Mercenary, Earth (Or rather, the United Nations of Sol) seems to have certain population-control measures set up to prevent undesirable genetic characteristics from spreading to future generations. The only such limit that has been mentioned so far is for the overly moronic - basically, stupid people aren't allowed to have children - but one must assume that other characteristics are likewise limited. Since over-population isn't a problem (plenty of planets to colonize, and space-station colonies to boot), such people can still have children, though - by 'ordering' genetically-designed kids at private companies, getting them grown in tanks, and then raising them... apparently, the Nature-Versus-Nurture debate ended with victory for 'Nature' somewhere along the line.
- A variation in Dan and Mab's Furry Adventures , when the number of Souls of the Fae is physically limited. When one of them becomes "available", it can be given or auctioned, allowing one to produce offspring. They also sometimes let their soul randomly regenerate, causing, on one occasion, Mab's tea to turn into a baby.
- The Big Bad emperor of Red All Over orders every third child to be killed upon birth (and by draftees, no less).
- China's one-child policy, although there are many loopholes. * China's experienced the same "prosperity + improving women's rights = smaller families" formula as happened in the West starting in the '60s and '70s - the one-child policy now largely stands on its own institutional inertia.
- Combined with an equally inertial culture of misogyny, this leads to couples killing baby daughters so they can try again for a son. This has finally started to bite China in the ass, as now China Needs Women.
- And before the policy was instituted China encouraged births.
- Nazi Germany had a variation as well. "Pure" Aryans were encouraged to have as many children as possible, and birth control was outlawed. "Undesirables," including those of other races and the mentally handicapped, would be forcibly sterilized or killed.
- Rather violently inverted in Romania under communist rule. President Nicolae Ceauşescu outlawed abortion, birth control and sex education, and instituted a "celibacy tax" for women who failed to have children, with the goal of increasing the country's population. It worked, but it didn't end well. The generation he created turned out to be the one that overthrew him, ironically.
- Like the seaQuest DSV example above, the Marcos reign in the Philippines had death squads unofficially target street children.
- Partially inverted in the time of Louis the Sun King in France, when any family with ten or more children was tax-exempt in order to boost the population for more soldiers a generation down the line.
- In Vietnam during the 1960's, they had a two-child policy. It was stopped in 2003, although they are considering reviving it.
- Some regional governments in poorer parts of India have introduced the "honeymoon bonus", offering money to newlyweds who agree not to have children.
- Also to young men who agree to get vasectomies, even if they aren't married.
- In Russia, Vladimir Putin's government introduced financial reward schemes to encourage people to have more children. It's unclear to what extent it was responsible (probably not very much), but since then Russia's population has stabilised and is once again growing slowly.
- A similar system has been implemented in Ukraine, although it has a reduced effect, as the population growth is still negative. This has resulted in many kindergartens shutting down (why keep them open when they make no money), and any parents requiring to get in line almost as soon as their child is born in order to have a shot at putting their child into one of the remaining ones.
- Inverted in the New France colony where people where given a reward to have many children.
- Likewise inverted in Fascist Italy, where women were given medals for having many babies, and soldiers were required to salute pregnant women.
- Somewhat inverted in the case of the Soviet Union, where there was a tax placed on being a bachelor. While it is not explicitly a pro-birth measure, the implication was that it would lead to more births.
- The idea was that anyone who didn't marry and have kids didn't contribute enough to the state and the people. After all, any child is a future worker/peasant loyal to the party.
- Although not state-enforced (and is in fact a level of embarrassment to the government), Japan is currently undergoing a self-inflicted state of population control, with its growth rate currently being negative (as in more people die than are being born). There are several factors towards this, but at the end of the day it is as the Useful Notes page says on the Japanese government, "Japan has forgotten how to make babies".
- Britain has gone back and forth on a fairly low-key inversion by offering tax credits to less wealthy couples with young children and recently a tax credit for getting married, presumably to appease the traditionalist wing of the Conservative Party after the legalisation of gay marriage. The cost of living is doing a pretty good job of playing the trope straight, incidentally; if not for the import of surplus workers from some of the newer EU members Britain might be in the same boat as Japan.
- Australia's "Populate or Perish" policy after World War II, as a response to the Yellow Peril. While a rise in the birthrate was encouraged, the main emphasis was on immigration as it would increase the population quicker.
