Trends in contraception and sterilization in Australia.

Life-history data collected in a national survey of women in 1986 are used to derive the first national estimates of trends in contraception and sterilization in Australia over the last 30 years. The pill rapidly became the method of choice after its release in 1961. The intrauterine device, the other truly modern method, has never attained the same popularity. The move toward sterilization dates from the early 1970s and has been so complete that women of 35 or older are now more likely to be protected by a ligation or laparoscopic sterilization than by the pill or, indeed, by all other methods combined. Unmarried women are now indistinguishable from married women on the basis of their use of contraception, and childless married women are now more likely to be using a reversible method than married women with children.
