Fertility is the ability to conceive (become pregnant) and give birth to children.
The total fertility rate is defined as the mean number of children who would be born to a woman during her lifetime, if she were to spend her childbearing years conforming to the age-specific fertility rates, that have been measured in a given year.
The age-specific fertility rate or the fertility rate by age of mother is the number of births to mothers of age x proportional to the average female population of age x.
