The global average for the replacement total fertility rate, eventually leading to a stable global population, for the contemporary period, 2010–2015, is 2.3 children per female. [ 11 ] [ 12 ] Comparison ranking lists:
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%.
Thus, the figures after the 1960 column show the percentage annual growth for the 1955-60 period; the figures after the 1980 column calculate the same value for 1975–80; and so on. The formulas used for the annual growth rates are the standard ones, used both by the United Nations Statistics Division and by National Census Offices worldwide.
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.
The population growth rate estimates (according to the United Nations Population Prospects 2019) between 2015 and 2020 [1] This article includes a table of countries and subnational areas by annual population growth rate.
A 2023 map of countries by fertility rate. Blue indicates negative fertility rates. Red indicates positive rates. The total fertility rate (TFR) of a population is the average number of children that are born to a woman over her lifetime, if they were to experience the exact current age-specific fertility rates (ASFRs) through their lifetime, and they were to live from birth until the end of ...
The net reproduction rate (R 0) is the number of surviving daughters per woman and an important indicator of the population's reproductive rate. If R 0 is one, the population replaces itself and would stay without any migration and emigration at a stable level. If the R 0 is less than one, the reproductive performance of the population is below ...
