This pure-blood vampiric race is not immortal, but their lifespans are about five times that of mortals. This race has lived in a vast city beneath a small mountain range for thousands of years (th...
I read a theory once which stated that the natural pain, sickness and general discomfort that humans can experience during sex, pregnancy, and childbirth help control the human population by discou...
How many people can live comfortably on planet Earth, assuming that humanity reaches Kardashev scale Type I level? This implies: Energy is cheap, and available in an almost unlimited quantity, c...
So, my colony mothership crawls along through sub-space at a "slow" ftl as it sends out faster probes ahead of it. Once it has located a cluster (meaning an acceptably dense grouping, not necessari...
I am working on a species that ressembles humans beings and that, although slightly engineered in the sense that the evolutionary leaps are aided by genetic modification, they are left to go throug...
I am working on a space game that allows players to participate in the human colonization of a distant star cluster. I could use some help determining what sort of numbers I should have aboard the...
There lives in a desert a large nomad culture, composed of many tribes who wander about herding camels, goats and sheep, trading and offering services to cities and towns, and occasionally raiding ...
Modern Earth; a series of connected events (natural disasters, mass migration, drug-resistant pandemic, collapse in biodiversity, armed conflict) have led to a significant reduction in human popula...
Ruins of buildings, abandoned cities and suburbs dot the coasts of Earth's landmasses, inhabited by wild animals and the pieces of a once vibrant civilization. The oceans are relatively empty, the ...
For an elf-like race whose people do not age beyond physical maturity (the accumulated DNA damage associated with aging does not occur), what would prevent overpopulation? This elf-like race is f...
Welcome to the year 2170, the predictions of our grandparents were so wrong: The human population didn't cap at 20 billion, it went far past that. The global population is now roughly 200 billion. ...
I want to know the how many people can live on Earth's oxygen. Is there a point when humans would use up all the oxygen? What would be the limiting factors? Given we have charts to show the rate of...
I'm imagining a near-future world where a process can be undergone that will halt all future aging of the body, but the approach causes infertility. Those undergoing it will not have (biological) ...
In figuring out the rough timeline for my sci-fi, I've run into an interesting dilemma. As it stands right now, There are about 90 years in between one of my civilizations discovering space travel ...
Warning picture showing dissected Russian Doll My theory I believe that Russian Dolls reproduce asexually. They are born pregnant. At the time of birth, the outer doll dies. What is now th...
So there's this planet that, several decades earlier, suffered a massive famine and drought that made habitation impossible. Everyone still alive on this planet died, except for 2 escapees, both of...
Question: I'm trying to determine how large (geographically) my city will have to be to accommodate for 1 million people. I have a city that was basically formed by the gods to be fertile land wit...
It is difficult to find statistics for the ratio of Lego men and women in the general population but from a non-scientific survey, I get the impression that Lego men vastly outnumber Lego women. Ye...
A perverse incentive is a reward system that has the opposite effect to the one intended. In Hanoi, under French colonial rule, a program paying people a bounty for each rat tail handed in wa...
How can we have a world that is inhabited only by zombies and yet continues to be populated? For the purposes of this question, I envisage the type of zombie that has been infected by a virus, is...
Pathogen Note: For the purpose of this question I define a pathogen to include viruses and/or bacteria. Edit: I don't exclude other biological agents such as fungi that might have the same effect...
The current world population is around 7 billion living people and 107 billion dead people. Since the population is increasing steadily and faster than ever, I was wondering if we could ever reach ...
Lets say for arguments sake, that a world, with maximum population of 5 billion, the common Joe gets reincarnated a few hundred times since the creation of humankind. This type of reincarnation is ...
Judging by the majority of answers from this question: What would be a logical reason to explain space based families having more children than an earth based one the spacers are going to have lots...
Suppose that we pare down human consumption to a minimum survivable level across the Earth, and devote the entire surface of the planet (as well as the planet's interior, if needed) to support as m...
In my yet to be named sci-fi universe humanity has begun to expand into space and has established large scale space stations near Earth and on places like Eros and Luna. I wanted the stereotypical ...
I'm attempting to rough-estimate potential population density of three-dimensional megastructures in space. Assume a filled spherical volume (i.e. death star, not Dyson sphere), where all internal ...
Everyone suddenly disappears from earth except 35 people randomly scattered wherever they were before everyone disappeared. How long would it take on average for 2 or more people to meet? What othe...
I'm worldbuilding for a story in which a certain portion of the population relocates to a slightly habitable planet due to the complete inhabitability of Earth. It takes place several generations a...
Essentially for my story my Evil Empire needs a constant and huge amount of new population to conscript for their armies. The way they accomplish this is by forcing every female member of society (...
Starting with about 500 humans and allowing for 900 years to pass, about how many people would there be at the end? (Just asking for a rough estimate, maybe a range.) Assuming: People are general...
I am looking for medically viable reasons why we might discover it to be more difficult than expected to bring pregnancies to term in space. This is for a society based approximately 75 years in th...
Okay, so we are figuring out, that at least for how we are running things now, our Earth can fit about 10 billion people. We can probably raise if your economy distributed resources more efficientl...
A train of thought is that a lot of our problems could be solved by reducing our numbers. For this question I am limiting it to environmental changes. For example: a successful species will increas...
I have a question that concerns a story I am writing and I hope it is a valid one to ask. But in my story, several groups of colonists, each arriving on different ships at relatively the same time...
Premise: Assume that one man has a genetic mutation such that his gametes (sperm) never have an X-chromosome. Unlike most men (who have a roughly 50/50 chance to sire a male or a female child) t...
With the increase in living standards, the number of children by women is decreasing in highly developed countries. Question: Is it conceivable (with the aggravating factors proposed below) to s...
The "Light-Year City" Questions "” What would be the gravitational implications of a city in the far, far distant future, with an area spanning one square light year (3.456 × 10^25 mi² area)? Th...
I can easily set a story in a dystopian environment not subject to ethics, but I would rather try to create a backdrop that is as ethical as possible given the requirements. I feel that writing abo...
I am making a game folowing the development of civilizations on an alien planet, however as i am almost done with the geography of this planet, i have come to realize that my continents which are s...
On my fictional planet humanoid aliens have evolved on one continent, and have since spread around the entire planet, just like humans did on Earth. On Earth humans have since developed slightly di...
I really think that we can feed way more than our current population using more advanced farming IF WE FIND A WAY TO PRODUCE CHEAP RENEWABLE ENERGY. The solution would be hydroponic vertical farms...
"It will be difficult enough to avoid disaster in the next hundred years, let alone the next thousand or million." "Our only chance of long-term survival is not to remain inward-looking on p...
WARNING THE FOLLOWING CONTAIN SPOILERS! I watched the first season of The 3% and I am wondering about the wisdom in the strategy adopted by this world. Spoilers Specifically, if the 3% ( "smar...
I want to create a world set on our Earth but with humans shrunk down as much as possible to allow a huge population. As the population increases they genetically modify their bodies to be as smal...
It is well known that in respiration, we produce carbon dioxide, while plants, via photosynthesis, absorb CO2. My question is, if 50% of all people die today, will the total amount of CO2 decrease ...
In my world (set in the near future - no magical tech), every child after reaching the age of 1, is sent to study for 15 years in a centralised location shared by the entire world. With some playin...
In my pre-bronze age city, there are roughly 20,000 individuals. 9,000 sexually mature males, 9,000 sexually mature females, and 2,000 children. For a variety of unimportant reasons, they have been...
In Star Gate, the Ori are notorious for keeping the tech level of their planetary subjects at or under medieval tech levels. It has been said (still looking for the exact source) that if everyone l...
Let's say, we've surpassed all tolerances of population. But, mega-corporations found a creative way to solve the problem. They dug into the Earth to build bubble cities in magma. They have access ...
