title: Births to teenagers in the United States, 1940-2000.
abstract: OBJECTIVE
  This report presents trends in national birth rates for teenagers, with particular focus on the decade of the 1990s. The percent change in rates for 1991-2000 is presented for the United States, and the change for 1991-99 is presented for States.
  
  
  METHODS
  Tabular and graphical descriptions of the trends in teenage birth rates for the Nation and each State, by age group, race, and Hispanic origin, are discussed.
  
  
  RESULTS
  Birth rates for teenagers 15-19 years generally declined in the United States since the late 1950s, except for a brief, but steep, upward climb in the late 1980s until 1991. The 2000 rate (49 births per 1,000) is about half the peak rate recorded in 1957 (96 per 1,000). Still the U.S. rate is considerably higher than rates for other developed countries. During the 1990s rate declines were especially large for black teenagers. State-specific rates fell significantly in all States for ages 15-19 and 15-17 years, and in all but three States for ages 18-19 years. Overall the range of decline in State rates for ages 15-19 years was 11 to 36 percent. For teenagers 15-17 years, the range of decline by State was 13 to 43 percent. Reductions by State were largest for black teenagers 15-19 years, with rates falling 40 percent or more in seven States. The factors accounting for these declines include decreased sexual activity reflecting changing attitudes towards premarital sex, increases in condom use, and adoption of newly available hormonal contraception, implants, and injectables.
