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 ...
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
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]
Since 2007, when the fertility rate was at its most recent high, the number of births has declined 17%, and the general fertility rate has declined 21%, according to the new report.
The general fertility rate, the annual number of live births per 1,000 women of childbearing age (often taken to be from 15 to 49 years old, but sometimes from 15 to 44). The age-specific fertility rates, the annual number of live births per 1,000 women in particular age groups (usually age 15–19, 20–24 etc.)
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 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.
While birth rates are decreasing in most age groups there is one notable exception: rates for women in their 40s are increasing.
