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 ...
Fecundity is defined in two ways; in human demography, it is the potential for reproduction of a recorded population as opposed to a sole organism, while in population biology, it is considered similar to fertility, [1] [2] [3] the natural capability to produce offspring, [4] measured by the number of gametes (eggs), seed set, or asexual ...
Fertility in colloquial terms refers the ability to have offspring. In demographic contexts, fertility refers to the actual production of offspring, rather than the physical capability to reproduce, which is termed fecundity. [1] [2] [3] The fertility rate is the average number of

Fertility rates around the world are dropping quicker than expected, putting the world on track to see a population decline before the end of the century, according to a report from the United ...
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.
Fertility rates must level off to the replacement rate (the net reproduction rate should be 1). If the fertility rate remains higher than the replacement rate, the population would continue to grow. 2. Mortality rate must stop declining, that is, it must remain constant. 3. Lastly, the age structure must adjust to the new rates of fertility and ...
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.
