What proximate determinants of fertility?

Proximate determinants of fertility are the biological and behavioral factors that influence reproductive outcomes within a population. Key determinants include the age at which women begin childbearing, the frequency of sexual intercourse, the use of contraception, and the duration of postpartum infecundability. These factors directly affect the number of births a woman may have during her reproductive years. Understanding these determinants helps in analyzing fertility patterns and trends in different societies.
