The replacement fertility rate is 2.1 births per female for most developed countries (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 ...
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.
As of 2009, the average birth rate (unclear whether this is the weighted average rate per country [with each country getting a weight of 1], or the unweighted average of the entire world population) for the whole world is 19.95 per year per 1000 total population, a 0.48% decline from 2003's world birth rate of 20.43 per 1000 total population.
Total fertility rate in Korea. South Korea has the lowest fertility rate in the world at 0.78. [57] A variety of explanations have been proposed, ranging from investment in education [58] to birth control, abortion, a decline in the marriage rate, divorce, female participation in the labor force, and the 1997 Asian financial crisis.

The total fertility rate in South Korea sharply declined from 4.53 in 1970 to 2.06 in 1983, falling below the replacement level of 2.10. The low birth rate accelerated in the 2000s, with the fertility rate dropping to 1.48 in 2000, 1.23 in 2010, and reaching 0.72 in 2023. [51] One example of Korea's economic crisis is the housing market.
During the period 2015–2020, the average world fertility rate was 2.5 children per woman, about half the level in 1950–1955 (5 children per woman). In the medium variant, global fertility is projected to decline further to 2.2 in 2045–2050 and to 1.8 in 2095–2100. [25] [26]
