Abstract
Korea has been widely recognized as the most successful country for reversal of the rise in sex ratio at birth (from the mid-1980s to the mid-1990s) in a short period of time. However, unusually high sex ratios at birth are still observed in most regions as parity increases. Given that imbalanced sex ratios at high birth orders are mostly due to son-selective abortion, it still remains questionable whether son-selective reproductive behavior has vanished in Korea. The main purpose of this study is to analyze the pattern of changing trends and socioeconomic differentials in sex ratio at birth. Micro-data from birth registration for 2009 are utilized. Attention is focused on analyzing sex ratios at birth in Youngnam region according to age of mother, parity, educational attainment of parents, and occupation of parents. A series of simulations are also conducted in this paper to show how prenatal sex screening and son-selective abortion have affected the level of sex ratio at birth for years 1994, 2005 and 2009.
