Replacement fertility is the total fertility rate at which women give birth to enough babies to sustain population levels, assuming that mortality rates remain constant and net migration is zero. [10] If replacement level fertility is sustained over a sufficiently long period, each generation will exactly replace itself. [10]

The net reproduction rate (R 0) is the number of surviving daughters per woman and an important indicator of the population's reproductive rate. ... Rwanda: 1.714 ...
This is a list of countries showing past fertility rate, ranging from 1950 to 2015 in five-year periods, as estimated by the 2017 revision of the World Population Prospects database by the United Nations Population Division. The fertility rate equals the expected number of children born per woman in her child-bearing years.

The mean age at childbearing indicates the age of a woman at their childbearing events, if women were subject throughout their lives to the age-specific fertility rates observed in that given year. [1] In countries with very high fertility rates women can have their first child at a much younger age than the mean age at childbearing.
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 ...
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 ...
