Despite the massive attention drawn to 'missing girls,' there has been no study that specifically focuses on the association between childlessness and the daughter deficit. Using a bivariate probit selection model, this article analysed the data for 6475 married women aged 15-49 years collected from the 2003 Korea National Fertility and Family Health Survey. The results showed that a couple's decision to have a child exerted a significant influence on its daughter deficit. This study also found that the effect of a woman's education on daughter deficit did not correspond to that of her husband's level of education. Additionally, a prediction was made that if a one child family norm were prevailing in South Korea, the probability of a couple's having a daughter deficit would increase by as much as 63.9%.
