📋 Key Findings
🔍 Background
This report analyzes population changes by tracking residential moves across administrative boundaries (Eup, Myeon, Dong) based on move-in reports. This data serves as a foundation for establishing national policies.
📌 Key Points
The number of migrants in December was 528,000, with a mobility rate of 12.2%, up 0.1%p from the previous year. Total migrants in Q4 2025 reached 1.398 million, a 7.5% decrease compared to the same period last year.
📝 Implications
Significant population inflows were observed in Gyeonggi (4,654) and Chungbuk (3,853), while Seoul (-4,887) experienced a net outflow. A 4.5% increase in inter-provincial moves indicates more active regional population redistribution.
📝 Impact on Daily Life
Regions with continuous inflows, such as Chungbuk and Gyeonggi, are expected to see rising demand for housing and public services. Outflow areas like Seoul and Gwangju must prepare for changes in local economic vitality.
