Using sexual exclusivity as an indication of commitment to a partner,
we examine commitment within dating, cohabitation, and marriage, Emplo
ying data from the National Survey of Women (1991), we find that cohab
itation, in terms of sexual commitment, is more similar to dating than
marriage, and that cohabitation, relative to marriage is selective of
less committed individuals. In addition, limiting our analyses to cur
rently married women, we find that the characteristics emphasized in p
artner selection by those who cohabit before marriage differ from the
characteristics emphasized by those who do not cohabit before marriage
, and that these characteristics influence sexual exclusivity among pr
ior cohabitors.
