Some major findings from the 1972 survey of family planning knowledge, attitudes, and practice (KAP) are presented, particularly those related to relationships between family planning and various demographic and social variables, in order to describe the current status of family planning knowledge, attitudes, and practice in the Philippines. Attention is directed to some rather substantial changes that have occurred since 1968, as revealed by comparison of 1972 data with selected findings of the 1968 National Demographic Survey. The sample was chosen according to a multi-stage probability sampling design. All sample households with ever-married women aged 15-49 were included in the survey. A total of 9232 every-married women from 11,837 households were interviewed. The percentage of women who indicated that they did not want an additional child increased as the number of living children increased. The largest percentage of women in the sample had 3 or 4 living children; 69% of these women stated that they did not want an additional child. The median number of children desired showed a corresponding decline from 5.1 in 1968 to 3.9 in 1972. Among both urban and rural women, there was an increase between 1968 and 1972 in the percentage of women who stated an ideal or desired family size of 4 or fewer children. The increase was greater in all categories among rural women than among urban women, indicating that family size norms are changing more rapidly in the rural areas. In contrast to 1968, when only 4% of all respondents were able to recognize at least 1 contraceptive method when it was mentioned to them, in 1972, 86% could identify at least 1 method without assistance. Of all contraceptive methods, knowledge of the IUD showed the largest increase since 1968. Both surveys established positive correlation between education and income and approvalof family planning, while age and number of living children did not appear to exert much influence on a woman's attitude. Contraceptive practice (ever-use) increased from 19-32%. Almost all women who indicated that they had used a method recently were still current users at the time of the survey. Rhythm, oral contraception, and withdrawal were the most commonly used methods. The largest percentage of contraceptive materials were supplied by druggists and local physicians; family planning centers supplied about 1/4 of all respondents with pills and IUDs.
