The use of contraception increases with increasing education. Sixty percent of women with at least some secondary education use a contraceptive method, in contrast to 43 percent of women with no education. In general, women do not begin to use contraception until they have had at least one child. Fifty-two percent of women currently in union with three or four children are currently using a modern method of contraception. The use of modern methods among women currently in union peaks between age 25-39 (50-52 percent). There is a small variation in the use of modern methods between urban and rural areas.
