RESUMO
PIP: 2 surveys were conducted in 1968 and 1979 in the same medium and low income neighborhood of Sorocaba, Brazil, to investigate modifications in contraceptive practice. The number of women knowing about contraception went from 68.9% to 94.6%, but the percentage of women actually using contraception decreased from 58.7% to 39.9%. Among those using contraception there was a marked increase in OC (oral contraception) use and a marked decrease in coitus interruptus and condom use. During the period of 11 years the yearly income of surveyed people had increased about 20%; however, the number of contraceptive users had increased only among women with higher income and better education, it had decreased in all other groups. The use of the pill was relatively higher among Catholic women^ieng
