Current data indicate a significant increase in the "feminization of international migration" over time. This report aims to review, analyze, and compare existing data collections on migrant flows and stocks in Korea to showcase different migration patterns and processes at the national level, with a specific focus on gendered marriage migration. The paper examines various characteristics of marriage migrants in Korea, including their sex, age, type of residence, nationality, naturalization status, and employment status. Additionally, it explores the recent impacts of the pandemic on migration trends within a historical context. Furthermore, the report discusses policy issues related to migrants in multicultural families and briefly examines the policy effects over the past decade. It highlights the importance of collecting and analyzing high-quality, sex-disaggregated data and gender statistics to better understand gendered migration patterns, inform policy objectives, and address relevant issues and strategic trends within the Korean context.
