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.

The mean age at childbearing indicates the age of a woman at their childbearing events, if women were subject throughout their lives to the age-specific fertility rates observed in that given year. [1] In countries with very high fertility rates women can have their first child at a much younger age than the mean age at childbearing.
