Until now, the causes of unmarried population have been found in young people's marriage and childbirth values, socioeconomic and residential characteristics, but the imbalance in birth sex ratio that has continued for 30 years since the early 1980s has created a population structure in which people cannot get married even if they want to.
In this study, demographic indicators were calculated to see how the sex ratio imbalance at birth affected Korea's current population structure, and future trends were also analyzed. We also looked at the policy needs of young people. Please refer to this report for further details.
