This article argues that marriage and cohabitation are associated with
important differences in work patterns, earnings, treatment of money,
use of leisure time, social relations with the extended family, the d
ivision of household labor, and fertility. We hypothesize that these d
ifferences lead those considering the formation of a household to cons
ider their attitudes toward these aspects of life, which appear to be
so different in marriage from those in cohabitation. Using data from t
he National Longitudinal Study of the High School Class of 1972, we te
st and find support for the hypothesis that the choice between cohabit
ation and marriage is affected by attitudes and values toward work, fa
mily, use of leisure time, money, and sex roles, as well as values and
attitudes toward marriage itself.
