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] The fertility rate is the average number of children
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]
France has been successful in increasing fertility rates from the low levels seen in the late 1980s, after a continuous fall in the birth rate. [41] In 1994, the total fertility rate was as low as 1.66, but perhaps due to the active family policy of the government in the mid-1990s, it has increased, and maintained an average of 2.0 from 2008 ...
Female fertility is affected by age and is a major fertility factor for women. A woman's fertility is in generally good quality from the late teens to early thirties, although it declines gradually over time. [1] Around 35, fertility is noted to decline at a more rapid rate. [1] At age 45, a woman starting to try to conceive will have no live ...
Income and fertility is the association between monetary gain on one hand, and the tendency to produce offspring on the other. There is generally an inverse correlation between income and the total fertility rate within and between nations. [ 3 ][ 4 ] The higher the degree of education and GDP per capita of a human population, subpopulation or ...
Gross reproduction rate. 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 ...
Frequency. 113 million (2015) [1] Infertility is the inability of an animal or plant to reproduce by natural means. It is usually not the natural state of a healthy adult, except notably among certain eusocial species (mostly haplodiploid insects). It is the normal state of a human child or other young offspring, because they have not undergone ...
