The CIA World Factbook gives the world annual birthrate, mortality rate, and growth rate as 1.86%, 0.78%, and 1.08% respectively. [29] The last 100 years have seen a massive fourfold increase in the population, due to medical advances , lower mortality rates, and an increase in agricultural productivity made possible by the Green Revolution .
The UN Population Division report of 2022 projects world population to continue growing after 2050, although at a steadily decreasing rate, to peak at 10.4 billion in 2086, and then to start a slow decline to about 10.3 billion in 2100 with a growth rate at that time of -0.1%.
The CIA World Factbook gives the world annual birthrate, mortality rate, and growth rate as 1.915%, 0.812%, and 1.092% respectively [5] The last one hundred years have seen a rapid increase in population due to medical advances and massive increase in agricultural productivity [83] made possible by the Green Revolution.

Birth rate and mortality rates can change rapidly due to disease epidemics, wars and other mass catastrophes, or advances in medicine and public health. The UN's first report in 1951 showed that during the period 1950–55 the crude birth rate was 36.9/1,000 population and the crude death rate was 19.1/1,000. By the period 2015–20, both ...
Falling birth rates have put major global economies on the path toward "population collapse," according to a report from McKinsey Global Institute. By 2100, some counties could see their ...
Crude mortality rate refers to the number of deaths over a given period divided by the person-years lived by the population over that period. It is usually expressed in units of deaths per 1,000 individuals per year. The list is based on CIA World Factbook 2023 estimates, unless indicated otherwise.
While world population growth remains brisk, growing from 6 billion to 8 billion since the turn of the millennium, the rate has slowed since doubling between 1960 and 2000. People living to older ...
Rates are the average annual number of births or deaths during a year per 1,000 persons; these are also known as crude birth or death rates. Column four is from the UN Population Division [3] and shows a projection for the average natural increase rate for the time period shown using the medium fertility variant. Blank cells in column four ...
