A representative sample of 5892 acceptors reported by Philippine program clinics from December 1969 through June 1976 were interviewed in order to provide a reasonably accurate estimate of 1977 contraceptive prevalence. It was learned that about 32% of eligible couples (1,720,000 couples) were practicing some method of contraception. Nearly 1/2 of the couples were using 1 of the more effective methods -- OC (oral contraception), IUD, or sterilization. Findings from adjusted survey data indicated an upward trend in the prevalence of all program methods between 1968 and 1976, but a net decline between early 1976 and early 1977 because of sharp declines in the number of OC and condom users which were not totally offset by increases in sterilization and IUD prevalence. The trends in estimated prevalence suggested a decline of about 4 points in the crude birthrate during the 1972-1977 period and an 0.3% point decline in the population growth rate for the same period.
