Split from Absurdly Huge Population following discussion.
Launching alongside Absurdly Huge Population in six hours unless someone has additions.
The population of an area, whether it be a small region, a country, a planet, or a Galactic Superpower has grown so large it is causing problems. The result might be societal instability, war, ecological catastrophe, cannibalism... the specifics do not really matter - what matters is that there are too many people and it is causing problems. This is often a feature of a dystopia and Cyber Punk, and can be used as a form of Green Aesop, i.e. "we have to get a handle on our population growth now or else this is our future."
May be prevented or resolved through the use of Population Control, settling new, uninhabited places, or even good old fashioned Depopulation Bombs if the powers that be feel it is the only way. If unhandled , the crisis can cause The End of the World as We Know It if it grows severe enough as riots run rampant for what resources remain.
Overlaps with Absurdly Huge Population when the increased population is used as a shorthand for "Of course there will be more people, it's the future."
- An overpopulation-induced resource crunch is stated in the introduction of Serenity to have prompted the settlement of the star cluster the Firefly franchise takes place in, and led to Earth becoming Earth That Was.
- A central theme in Soylent Green. Earth is so overpopulated that the only way to feed the people is through a product called Soylent Red and Yellow. A new product called Soylent Green comes at the market and in the films climax it turns out that it is made of people!
- In "The Mark of Gideon", an Anvilicious episode of Star Trek: The Original Series, the crew visit a planet which is so overpopulated that even the president's office has a crowd of people milling around in the background. The people of the planet believe "all life is sacred" and reject birth control. They also have medicine so advanced that people never get sick and live to a very old age.
- Elysium: Among the problems that plague the dystopian Earth of the future is overpopulation, along with high crime, poverty, and medicine being restricted to the rich on Elysium. At the end of the film, all of Earth's people are approved as Elysium citizens and so can receive medicine, but the director admitted afterward that this was an Esoteric Happy Ending that would only worsen the overpopulation problem.
- Three of George R.R. Martin's Tuf Voyaging stories (''Loaves and Fishes", "Second Helpings" and "Manna from Heaven") chronicle Haviland Tuf's encounters with the people of the planet S'uthlam. Their religion has the doctrine that all life is sacred and that humans should therefore breed as much as possible. As a result, their planet is dangerously overpopulated.
- Isaac Asimov wrote The Winnowing which has six billion people on the planet, and famines are thus widespread. While that prediction has shown to be wrong in Real Life, at the time of its writing it was definitely an example of this trope.
- In Aeon 14, the Sol system's government resorted to extrasolar colonization beginning in the 2100s to try and deal with population-induced resource strains, hence the colony ship Intrepid around which the series revolves. Even so, it's mentioned once in the early books that the Sol system's population in 4123 is now so high that they're in danger of mining out the entire Sol system within the main characters' (admittedly hundreds of years long) lifetimes. The advent of Faster-Than-Light Travel in the 5,000 year Time Dilation-induced Time Skip between books 3 and 4 takes the strain off, but also causes a partial collapse of civilization and loss of much knowledge because interstellar warfare is now practical and humanity no longer has to be as efficient with its resources.
- A recurring theme in many of Robert A. Heinlein's novels, to which the solution is often Faster-Than-Light Travel:
- When the Howards' families return to Earth at the end of Methuselah's Children they find that the planet has become so crowded that there's literally no room left for them, fortunately one of the Howards has invented FTL and offers it freely. Still, in the distant sequel Time Enough for Love Lazarus Long mentions in one of his stories that at one point Earth's government declared everyone over 70 to be legally dead in an attempt at population control.
- Tunnel in the Sky: China apparently conquered Australia and paved over the entire continent to make room for its growing population before the Portal Network was developed, now they chuck hordes of settlers to new worlds through the gates.
- Starship Troopers: Rico writes an essay on how war is always the result of overpopulation, from the Crusades to the current Bug War. And that humanity doesn't dare institute Population Control, lest some other species like the Bugs expand first and wipe them out for more real estate.
- Farmer in the Sky: The Earth has so many people that everyone on the planet is put on strict food rationing. It's the major reason why the protagonists decide to emigrate to Ganymede (one of Jupiter's moons). Late in the novel one of the characters says that Earth's overpopulation will inevitably lead to a nuclear war within 40-70 years.
- In The Starchild Trilogy by Frederik Pohl and Jack Williamson, the population of Earth has reached the thirteen billion mark, and the only thing which has prevented chaos and a massive die-off is the dictatorial control of the powerful computer known as "The Plan of Man".
- In The Three Stigmata of Palmer Eldritch by Philip K. Dick, all the planets of the solar system have been colonized, but Earth is still so overpopulated that the government has had to institute a draft to get people moving to the colonies fast enough. Life on the colonies isn't terrible, but it's harsh enough that volunteers don't begin to keep up with Earth's needs. Deferments are available for those with sufficiently important jobs, but this just adds an extra fear to the fear of losing your job.
- In Larry Niven's Known Space books, Earth is so crowded that picking pockets isn't illegal - how could it be enforced?
- Ender's Game: Due to overpopulation, most of Earth's nations have enforced laws stating families are to have no more than two children. However, a few nations such as Poland openly flout the law, with many large families but the consequence being that only the first two children are eligible for public education and benefits. The protagonist, Ender, is a rare example of a state-approved Third, as the International Fleet authorized his parents to have another child because they recognized military potential in their first two. Since Peter and Valentine were examined but rejected them for various reasons (Peter for being too aggressive, Valentine as too pacifistic), the military hopes Ender might be a balance of their traits.
- In the Warrior Cats prequel series Dawn of the Clans, the series starts with the Tribe of Rushing Water suffering from overpopulation: the Tribe has grown too big to survive on the amount of prey that their environment can provide, and cats are starving to death. Their leader has a vision of new lands teeming with prey, and half the Tribe leaves, eventually becoming the forest Clans, while the other half remains in their mountain home and is able to support themselves better with fewer mouths to feed.
- Overpopulation is what jumpstarts the plot in Terra Nova - the plot being "send some humans through a wormhole to an alternate Earth resembling the cretaceous period."
- Warhammer 40K: Most Imperials live in hives, vast structures that can hold billions of humans in abject poverty and crime, several thousand in decent conditions, and the ruling elite in great luxury. Press-ganging large amounts of the population into military service is considered a perfectly acceptable way to keep the populace, criminals and mutants under control.
- Mass Effect:
- Even after the development of Faster-Than-Light Travel, it's noted In-Universe that in the late 22nd Century, Earth is still vastly overpopulated, with over 11 billion humans and an unknown number of aliens living on the planet, and dealing with problems caused by environmental damage which peaked a century ago. Earth's overpopulation and pollution is mocked by many aliens in the series, as an indication of humanity's inability to get its own "house in order", so to speak. A possible origin for protagonist Commander Shepard is to have grown up in a gang of orphan criminals in a polluted megatropolis on Earth.
- Drell society collapsed into warlordism due to the overpopulation of their homeworld, which they were unable to escape due to having no element zero. The hanar took pity on them and brought many of the survivors to their own homeworld Kahje as a Servant Race.
- After being uplifted from their homeworld to fight rachni, the Krogans found little opposition that would keep their natural birthrate in check, often overpopulating planets in just a few generations. The Salarians responded by devising a genophage which would make only one in a thousand krogan births viable. It would supposedly revert Krogans' birthrate to what it was back on Tuchanka with all the fatality rates taken into account, which was sustainable... But the Krogans saw this as their descent into a Dying Race, and turned to mercenarism to cope with their natural Blood-knight tendencies... which put their species at actual risk of extinction.
- Crusader Kings II:
- Played with for nomads such as the Khazars and Mongols. The Nomad government form has a special resource called "population" and get bigger armies and increased income the longer it is allowed to grow. Once it reaches 90% of maximum, they gain access to the unique "Nomad Invasion" casus belli which allows them to conquer entire de jure kingdoms from other realms. This essentially means overpopulation is good for the nomads and bad for everyone else (since their cavalry- and horse archer-heavy armies can be difficult to counter).
- The "Prosperity" measurement added in The Reaper's Due measures wealth and population of a province. Higher Prosperity increases your tax income and can unlock additional holding slots in a province, but also increases the province's vulnerability to epidemics. It also has an opposite form, "Depopulation".
- In Civilization V every city has an assigned number representing its population. Densely populated cities will produce more research and are able to work more tiles and specialist spots. They also produce more unhappiness which, if left to fester will severely decrease your nations growth and golden age frequency. If your citizens are unhappy enough, civil wars might break out.
- In Black & White 2, it's not the population itself so much as population density that causes problems. Your citizens will become unhappy if there is insufficient housing or food resources, or if their housing is too tightly packed (e.g. "skyscrapers", really tenements, are efficient with space but bad for happiness, while mansions with lots of space between them make for happy citizens but require lots of building room; villa clusters are generally the best choice).
- The Ark in Brink is a City on the Water which was originally designed to host a population of 5000, but an influx of refugees due to global warming caused its population to swell to 45000. As a result, many of these refugees were forced to live in poorly designed and shoddily constructed shantytowns, and many feel resentment toward The Founders, Ark's original inhabitants who live in safety and luxury.
- Inverted in Pharaoh, and Emperor: Rise of the Middle Kingdom where underpopulation is a much bigger problem: due to the game mechanics, huge populations are easier to maintain by keeping the population happy in attractive, high-density housing rather than vast slums (the basic hut holds 5-20 people, the best high-density housing holds 80). Yes, the people consume more, but the higher population means more people to produce goods at a much faster rate than consumed.
- In Stellaris:
- if an Empire's population exceeds its' food supply a "starvation" penalty to the population's happiness is applied that scales with the size of the food deficit. Though under the game mechanics it's impossible for the population to exceed the food supply with normal growth, it has to happen through immigration (voluntary or otherwise) or destruction of farms.
- On a more macro scale, Stellaris has always had a limit of planets that the central government (i.e. the player) can manage at one time... exceed this limit, and the inefficiencies can cripple the government's ability to manage its resources. Putting excess planets into sectors offsets this at a decreased cost of income from all systems in that sector (you will make at most 75% of the sector's total income, due to the sector keeping some to manage its own growth).
- Population can also cause problems for research and unity productions, as the cost of new technologies and traditions is increased with every pop past the first 10 and drasticly increased for every colony after the first one. Usually a balanced colony layout will mostly counter this malus (especially for research) but developing a colony in the first place takes quite some time. As such empires that expand too rapidly in the beginning will soon find themself outmatched technologicly by his neighbours and takes a long time (or a lot of help) to catch up. In this case the Overpopulation Crisis will not come from the population itself, but from its sudden, rapid expansion without having the infrastructure to actually sustain it.
- Consumer Goods were introduced specificly to cause this for giant empires. They are a constant decrease for an empires mineral income with a base cost of 0,5 minerals per pop (at Decent Living Standart) and increase in cost by 0,01 minerals per colony. This means that they have an exponential increase in cost, as while a new colony increases the amount of Goods needed (for the new pops) it also increases the cost of minerals for every Good in your empire. As such, their cost is only trivial for small empires, but potentially becomes a massive problem for big blobs.
- This was a real scare in the Cold War era. The population of Earth was rising and there would soon be too many people to sustain. Since then technology has marched on along with society and not only is the population growth slowing down (the population is projected to stagnate around the 11th billion), but we also produce more food than ever and the percentage of people living in extreme poverty has never been as low as of this writing.
- This does not mean that localised instances of this trope are not a thing. Many cities are struggling under the increased traffic that increased population brings because the original city was built in such a way that roads which formerly allowed for horse-drawn carts now need to support the eighteen-wheeler trucks and the huge numbers of cars needed to support the population. Add in a need to dig up roads to perform sewer/cable/pipeline maintenance and you have the city equivalent of growing pains.
