This government publication presents statistics and discussion on teenage marriages, divorces, parenthood, and mortality. In sheer numbers teenagers account for a large share of the marriages and births, especially illegitimate births. In 1969, about one-third of all brides and 14 percent of grooms were teenagers; in 1968 17 percent of all births and nearly 50 percent of the illegitimate births were to teenage mothers. On the other hand, the proportion of divorces granted to teenagers is small. More significant is the large proportion of divorces granted to persons who married in their teens (46 percent for women and 19 percent for men). The total number of deaths among teenagers also is small, and the death rate from all causes combined is low. Motor vehicle accidents, however, take a heavy toll from the teenage group; in 1969 the age group 15-19 years ranked a close second to the age group 20-24 years in more deaths from this cause than any of the other five-year age groups throughout the entire life span. These and other facts presented in this report on teenagers were derived from the vital statistics of the U. S. Bureau of the Census. Figures for marriages and divorces were obtained or estimated from data provided by states. Discussions of estimating procedures and of reliability of the estimate appear in the appendix to this report. (Author/PC)
