title: Estimates of the annual number of clinically recognized pregnancies in the United States, 1981-1991.
abstract: The authors estimated the number of clinically recognized pregnancies that occurred annually from 1981 to 1991 in the United States by type of outcome and by race. Estimates of the numbers of livebirths, induced abortions, ectopic pregnancies, and fetal deaths were obtained by using data from the Centers for Disease Control and Prevention in Atlanta, Georgia. The number of spontaneous abortions was estimated by using previously published, age-specific rates. More than 67 million pregnancies occurred during the study period. Overall, 62.5% of these pregnancies resulted in livebirths, 21.9% in legal induced abortions, 13.8% in spontaneous abortions, 1.3% in ectopic pregnancies, and 0.5% in fetal deaths. These data can be used to provide denominators for the calculation of a variety of pregnancy outcome-specific rates.
