Knowledge of, attitudes toward, and the practice of contraception among married women in Taiwan were examined in a series of six province-wide surveys conducted by the Taiwan Provincial Institute of Family Planning between 1965 and 1986. Each successive survey collected extensive data on contraception knowledge and use, pregnancy history, fertility, and family planning, along with information regarding family relations and residence history. KAP I (ICPSR 6862) included a focus on IUD users in 1965, while pregnancy, birth/death, and abortion data were collected in KAP II (ICPSR 6863) during 1967. KAP III (ICPSR 6864), administered in 1970, explored fertility levels and changes in contraceptive knowledge and use by following a panel of KAP II respondents, as well as an additional sample of women married between 1967 and 1969. Data from KAP II may be merged with the data from KAP III. The length of time different types of contraception were used and premarital family and nonfamily experiences of both the husband and the wife were examined in 1973 in KAP IV (ICPSR 6864). In 1979, KAP V (ICPSR 6866) gathered data on the marriage process itself, including how the marriage was arranged and what the living arrangements were prior to marriage. KAP VI (ICPSR 6967) was conducted in 1986 and investigated current and past residential arrangements, premarital and nonfamily experiences, and courtship and marriage processes.
