Age discrepancy in relationships:
According to the Family Research Council, studies in the US indicate that age discrepancy between the teenage girls and the men who impregnate them is an important contributing factor.
Teenage girls in relationships with older boys, and in particular with adult men, are more likely to become pregnant than teenage girls in relationships with boys their own age. They are also more likely to carry the baby to term rather than have an abortion. A review of California's 1990 vital statistics found that men older than high school age fathered 77 percent of all births to high school-aged girls (ages 16-18), and 51 percent of births to junior high school-aged girls (15 and younger).
Men over age 25 fathered twice as many children of teenage mothers than boys under age 18, and men over age 20 fathered five times as many children of junior high school-aged girls as did junior high school-aged boys.
