This set of factsheets presents information and statistics about adolescent mothers in the United States in the areas of: (1) births and marriage; (2) aid to families of dependent children (AFDC); (3) education and training; (4) living arrangements; and (5) subsequent pregnancy. Even though the adolescent birth rate in the United States is considerably lower than it was in the 1950s, births are more noticeable because most adolescent mothers are unmarried. Research also reveals that the perception that all adolescent mothers receive AFDC is incorrect. Adolescent mothers account for only a small percentage of the AFDC program at any given time, they account for the majority of AFDC households over time. Although the incidence of younger adolescent mothers is troubling, the vast majority of AFDC mothers are 18 or 19. Inadequate basic education and skills remain critical factors in adolescent pregnancy and childbearing. Few programs have been able to assist adolescent mothers in delaying a subsequent pregnancy, but those that do invest resources in intensive individual counseling and other individualized services. One table presents data on subsequent births. (Contains 45 references.) (SLD)
