The replacement fertility rate is 2.1 births per female for most developed countries (2.1 in the United Kingdom, for example), but can be as high as 3.5 in undeveloped countries because of higher mortality rates, especially child mortality. [11]
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 article lists 233 countries and territories in crude birth rate. The first list is provided by Population Reference Bureau. [1]
Birth rate, also known as natality, is the total number of live human births per 1,000 population for a given period divided by the length of the period in years. [1] The number of live births is normally taken from a universal registration system for births; population counts from a census, and estimation through specialized demographic ...
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 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 map of when European fertility rates fell below replacement levels Map of countries by crude birth rate. Map of countries by total fertility rate. Sub-replacement fertility is a total fertility rate (TFR) that (if sustained) leads to each new generation being less populous than the older, previous one in a given area.
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.
