Cohabitation and reproductive behavior in the U.S.

This paper examines the relation between unmarried cohabitation and three important determinants of fertility-frequency of sexual intercourse, contraceptive practice, and the expectation to have a child within five years. Analyses based on data from the 1982 National Survey of Family Growth show that formerly married cohabitants are similar to married women with respect to these fertility determinants, but that never married cohabitants may have lower fertility in the short run because of extremely high levels of contraceptive practice. The paper also compares self-reported data on cohabitation with an inferred measure based on household composition. [ABSTRACT FROM AUTHOR]
