The capital area recorded a net inflow of 38,000 people, but the scale of inflow decreased by 7,000 compared to the previous year. While the central region is seeing population growth across all areas, the Yeongnam and Honam regions recorded net outflows of 39,000 and 16,000 respectively, indicating a persistent regional population gap.

Approximately 6 out of 10 people leaving Seoul move to Gyeonggi Province, primarily for housing.
