Conducted in six rounds between 1965 and 1986, the Taiwan Women Health and Fertility Survey (known variously as the Knowledge, Attitude, and Practice of Contraception in Taiwan Survey, and Family and Fertility in Taiwan Survey) collects information from married women in Taiwan concerning their knowledge of and attitudes toward contraception, as well as their contraceptive practices. The survey also covers a range of demographic characteristics, including age, employment, education, and family composition. The data contains records for 4,312 cases of married women ages 20-49 in non-aboriginal townships in Taiwan.
