Fertility Determinants in Puerto Rico

Abstract

This paper examines the proximate determinants of fertility in Puerto Rico using data from a 1982 island-wide study. Contraceptive use was found to be the primary direct determinant of fertility in Puerto Rico, both for the total population and for each level of education studied. Female sterilization is the most prevalent method of contraception used in Puerto Rico at each educational level. Marriage is also important in Puerto Rico and is the only proximate determinant that varies across education groups. Late age at first marriage, in addition to high contraceptive use, accounts for the below-replacement fertility of women who have more than a high school education. In contrast, women who have not completed high school tend to marry early and not practice contraception for birth-spacing purposes. This study shows the advantages of analyzing fertility determinants at the population subgroup level (i.e., women of various educational attainment levels) so that the fertility of the total population can be better understood.
