Using data from the 1993 Ghana Demographic and Health Survey, this study ex
plores the relationship between ethnicity and sexual behavior: having sex b
efore age 17 and premarital sexual experience. All ethnic groups show subst
antial sexual experience before age 17 and premarital sexual engagement. Lo
gistic regression analyses reveal that in general ethnicity influences the
behaviors studied, especially for ever-married women. The data suggest that
groups that practice matrilineal and patrilineal systems show differences
in the likelihood of having sex before age 17. Contrary to expectation, the
re is an inverse relationship between education and sexual experience befor
e age 17. The findings highlight the importance of group-specific programs
in Africa.
