This study is intended to comparison of the recent ideal number of children and atrial approach for analyzing value system for children that form attitude affecting birth control with earlier study conducted 10 years ago. In general the traditional fertility pattern of Korea may be considered as 'early marriage and high fertility' backed by the confucian value system of a farming-oriented country. A selective attitude favoring sons contributes substantially to fertility. But Korea is now moving toward a late marriage and fertility pattern. This has been due to the repid introduction of western culture and a partial acceptance of western value systems, a relative weakening of traditional value systems, a gradual increase in infant and child servival rates thresh medicines, and a desire to avoid having too many children because of economic poverty. This study showed following results: Ideal number of sons and daughters in urban area was decreased by 0.2 respectively compared to earlier study.
