This research explores the current situation and determinants of induced abortion in Korea. Using 2000 National fertility Survey by Korea Institute of Health and Social Affairs, this study finds that induced abortion rate is rapidly declining so that the role of induced abortion in determining the level of fertility has disappeared. The fundamental reason for resorting to an induced abortion for Korean women is to avoid unwanted birth. Thus, we find that induced abortion is usually taken by Korean women for the purpose of limiting family size and spacing births as in any other countries. Premarital pregnancy and economic hardship are also important reason for taking an induced abortioin, especially for the first time abortion.
