A comparison of the results of the 1981 Contraceptive Prevalence Survey with those of a similar survey carried out in 1979-1979 shows that the proportion of currently marned Thai women who are practicing contraception has continued to rise and is now approaching 60 percent. Nearly all segments of Thai society have participated in this increase in contraceptive practice. Rural-urban and educational differentials are Znodest, and even among rural women with fewer than four years of education, more than half report that they are currently using contraceptives. Important regional differences remain, however; southern Thailand, particularly, lags behind the other regions.
