Since 1980, the number of legal abortions reported to CDC has remained fairly stable, varying each year by less than 3%. In 1986, 1,328,112 abortions were reported; in 1987, that number increased by approximately 2% to 1,353,671. The abortion ratio for 1986 was 354 legally induced abortions per 1,000 live births; the ratio for 1987 was 356 per 1,000. The national abortion rate was 23/1,000 females ages 15-44 years for 1986 and 24/1,000 females ages 15-44 years in 1987. Abortion ratios were higher among women of black and other minority races and among women less than 15 years of age. Women undergoing legally induced abortions tended 1) to be young, white, and unmarried, 2) to have had no previous live births, and 3) to be having the procedure for the first time. In 1987, approximately half of all abortions were performed before the eighth week of gestation, and greater than 85% were performed during the first trimester of pregnancy (less than 13 weeks of gestation).
