Field Listing :: Total fertility rate
This entry gives a figure for the average number of children that
would be born per woman if all women lived to the end of their
childbearing years and bore children according to a given fertility
rate at each age. The total fertility rate (TFR) is a more direct
measure of the level of fertility than the crude birth rate, since
it refers to births per woman. This indicator shows the potential
for population change in the country. A rate of two children per
woman is considered the replacement rate for a population, resulting
in relative stability in terms of total numbers. Rates above two
children indicate populations growing in size and whose median age
is declining. Higher rates may also indicate difficulties for
families, in some situations, to feed and educate their children and
for women to enter the labor force. Rates below two children
indicate populations decreasing in size and growing older. Global
fertility rates are in general decline and this trend is most
pronounced in industrialized countries, especially Western Europe,
where populations are projected to decline dramatically over the
next 50 years.
