Adolescent girls living in intact married families have the fewest sexual partners.
Female students in Grades 7-12 have an average of 0.71 sexual partners when they live in intact married families, whereas those who have a stepparent or divorced parents have an average of 1.39 and 1.29 sexual partners, respectively. In between are those whose parents never married (0.88), and those who live in cohabiting families with one natural parent (1.07) or both natural parents (1.15), according to the National Longitudinal Study of Adolescent Health, Waves I and II.
Many other studies corroborate this finding.2 Patricia Goodson of Texas A&M University and colleagues insist that family structure is one of the most well-documented environmental factors affecting early sexual activity in adolescent females. According to the literature, girls living apart from their biological fathers due to out-of-wedlock births or divorce are most likely to become sexually active.3
H. H. Cleveland of Texas Tech University also finds that adolescent girls from non-intact families generally have more sexual partners than those from intact families.4
J. C. Abma of the National Center for Health Statistics and colleagues found that 43 percent of female adolescents living with both parents, biological or adoptive, have ever had sex.5 Comparatively, 64 percent of female adolescents living without a parent have had sex. In between are those living with a parent and stepparent (55 percent) and those living with a single or cohabiting parent (59 percent).6
Mignon R. Moore of the University of Chicago reports that white adolescent girls not living with both biological parents are significantly more likely to have sex at an earlier age. In black and white single-parent families girls are more likely to have sex early than those living with both biological parents.7
Moore and P. Lindsay Chase-Lansdale of Northwestern University also find that a black female adolescent in a cohabiting family is more than three times as likely to be sexually active than a girl living with her married parents.8 The daughter of a single parent whose marriage was disrupted is three times more likely to be sexually active than if she were living with married parents.9
The evidence overwhelmingly confirms that female adolescents are least likely to engage in premarital sexual intercourse when raised in an intact married family. When parents belong to each other in always-intact marriage their children benefit sexually and are less likely to make early mistakes in this area of life.
