[Changing pattern of National Family Planning and Fertility Survey in Korea].

The authors review the evolution since the 1960s of South Korea's family planning and fertility survey programs. "In the 1960s, research was interested in respondents' contraception knowledge and practice rate and in the relationships between contraceptive knowledge and the practice rate....[The] major research emphasis in the 1970s and 1980s was measuring fertility and finding obstacles or problems to family planning projects." Recommendations for future research are made. (SUMMARY IN ENG)
