Name Total Fertility Rate
Definition The average number of live births a woman would have by age 50 if she were subject, throughout her life, to the age-specific fertility rates observed in a given year. Its calculation assumes that there is no mortality.
Calculation/Formula "(The sum of the Age Specific Fertility Rates x The number of years in each age group) / 1000 Note: Age Specific Fertility Rate (ASFR) = (Number of births to women in age group i / Number of women in age group i) x 1000 "
Range (eg Age) 15-49 years
Purpose/Rationale Family size and the number of children per woman fell substantially in many countries over the twentieth century, especially after 1960, a trend that is broadly favourable for sustainable development. High fertility is associated with increased risk of maternal morbidity and mortality. In most settings, women who have several children find it more difficult to work outside the home, thus having fewer opportunities to improve their economic and social status and that of their families. Low income households with many children often find it more difficult to get out of poverty than those with less children, and high fertility societies face greater demands for services from their youthful populations.
