The UN Population Division has calculated the future population of the world's countries, based on current demographic trends. The UN's 2024 report projects world population to be 8.1 billion in 2024, about 9.6 billion in 2050, and about 10.2 billion in 2100. The following table shows the largest 15 countries by population as of 2024, 2050 and ...
A population projection, in the field of demography, is an estimate of a future population. It is usually based on current population estimates derived from the most recent census plus a projection of possible changes based on assumptions of future births, deaths, and any migration into or out of the region being studied.

World population from 10,000 BC to AD 2000. The doomsday argument (DA), or Carter catastrophe, is a probabilistic argument that claims to predict the future population of the human species based on an estimation of the number of humans born to date.
“The population of 61 countries or areas are projected to decrease by 1% or more between 2022 and 2050,” the report says. ... for the foreseeable future, population increase in low-income and ...
Population of the present-day top seven most-populous countries, 1800 to 2100. Future projections are based on the 2024 UN's medium-fertility scenario. Chart created by Our World In Data in 2024. The following is a list of countries by past and projected future population. This assumes that countries stay constant in the unforeseeable future ...
Absolute increase in global human population per year [1] Population growth is the increase in the number of people in a population or dispersed group. The global population has grown from 1 billion in 1800 to 8.1 billion in 2024. [2] Actual global human population growth amounts to around 70 million annually, or 0.85% per year.
Because there are unknown factors that may affect future population changes, population projections often incorporate high and low as well as expected values for future populations. Population projections are often recomputed after a census has been conducted. It depends on how the area is adjusted in a particular demarcation.
Many studies have tried to estimate the world's sustainable population for humans, that is, the maximum population the world can host. [5] A 2004 meta-analysis of 69 such studies from 1694 until 2001 found the average predicted maximum number of people the Earth would ever have was 7.7 billion people, with lower and upper meta-bounds at 0.65 and 9.8 billion people, respectively.
