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 following list sorts countries and dependent territories by their net reproduction rate.The net reproduction rate (R 0) is the number of surviving daughters per woman and an important indicator of the population's reproductive rate.
Jamaica's annual population growth rate stood at 0.08% in 2022. As of 2023, 68.9% of Jamaicans were Christians in 2011, predominantly Protestant . A more precise study conducted by the local University of the West Indies - Jamaica's population is more accurately 76.3% African descent or Black, 15.1% Afro-European, 3.4% East Indian and Afro-East ...
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 ...
Crude birth rate refers to the number of births over a given period divided by the person-years lived by the population over that period. It is expressed as number of births per 1,000 population.
The gross reproduction rate (GRR) is the average number of daughters a woman would have if she survived all of her childbearing years, which is roughly to the age of 45, subject to the age-specific fertility rate and sex ratio at birth throughout that period. This rate is a measure of replacement fertility if mortality is not in the equation. [1]
