PIP: The data analyzed in this article show that, notwithstanding differences among agencies, funding sources, and regions, the organized family planning delivery system, as presently constituted, with a varied mix of provider agencies, is serving almost exclusively women of low or marginal incomes. About 9 in 10 of these women came from families at or below 200% of poverty; about three-quarters of them were from families at or below 150% of poverty level, and about 7 in 10 were from families at or below 125% of poverty. However, about 20% of women at or below 150% of poverty received family planning service from private physicians. As might be expected, as the number of patients served by organized programs grew, more than tripling between 1968 and 1972 to an estimated 2,612,000 women, so did the number of counties in which services were provides and the number of agencies providing the services. In the course of this rapid growth, the organized family planning programs became one of the major sources not only of medical contraception, but of other preventive health services. Most of the patients were young (media age was 23), of low parity (media was 1.8, including about 30% childless), with a high school education. Less than 1/6 (16%) were receiving public assistance.
