Fifteen million teens are not sexually active. But half will begin to have sex before they reach their twentieth birthday. The average teen becomes sexually active at age 16. Marriage Ninety percent of teenage sexual activity occurs outside of marriage. Only 6 percent of all teenage girls and 2 percent of all teenage boys are married.
Most teen marriages begin with a pregnancy.
Eight out of ten babies born to married 15 and 17 year old mothers were conceived before marriage. Marriages of teens 14 to 17 years old are three times more likely to end in separation or divorce than non-teen marriages. Abortion More than one-fourth of all abortions involve teens. Three out of five teens faced with an unintended pregnancy choose not to have the child. Among teens younger than 15, there are three abortions for every two births.
