Between 1982 and 1987, favorable opinion of the pill increased steadily among American women (from 65 to 76 percent), and favorable opinion of the condom rose sharply (from 38 to 60 percent). Approval of the IUD dropped during the period (from 26 percent to 19 percent). During the five years, the proportion of married women aged 18-44 who were exposed to the risk of unintended pregnancy remained the same (78 percent), but the proportion among unmarried women rose significantly (from 64 percent to 69 percent). This change was primarily the result of an increase--from 68 percent to 76 percent--in the proportion of never-married women who had ever had intercourse. The overall level of contraceptive use among 18-44-year-olds who were exposed to risk remained stable over the period, at about 93 percent, but use of the most effective methods (sterilization, pill and IUD) went up, from 68 percent to 71 percent. All of the net increase in effective-method use, however, was limited to married women, among whom reliance on both sterilization and the pill increased (from 46 to 51 percent and from 17 to 22 percent, respectively). Pill use also rose among unmarried women (from 43 to 48 percent), but there was no change in the level of sterilization. The prevalence of IUD use declined among both married and unmarried women (to three percent in each case). Condom use remained steady among married women, at about 15 percent, but among the unmarried it increased markedly, from nine to 16 percent.(ABSTRACT TRUNCATED AT 250 WORDS)
