The improvement in these indicators is attributed to a rise in the number of marriages and increased population inflow. The number of marriages in Gangdong-gu for 2025 reached 2,892, up about 34% from the previous year. The district’s population recently surpassed 500,000, and the influx and settlement of younger residents continues. The district government believes these trends will drive stable growth in birth-related indicators going forward and expects the upward trend in the number of births to continue for the time being.


To sustain this positive population trend, the district is implementing comprehensive support policies. It is improving access to information through the “Gangdong Mom-Friendly World” guidebook, which provides details on pregnancy, childbirth, and child-rearing. Diapers and standard garbage bags are provided to all households with newborns. Financial support such as special incentives for families with multiple children and entrance congratulatory payments are helping to ease the economic burden, and Gangdong-gu also offers the largest home service support program among Seoul’s districts. The “Gangdong-Style Teacher-to-Child Ratio Improvement Project” has also been significantly expanded to 63 institutions.


Mayor Sue Lee stated, “The increase in the number of births and improvement in the fertility rate are the result of efforts by both the district government and residents to create an environment where it is good to have and raise children. We will continue to serve as attentive supporters to ensure that parents and children can be happy in every stage from marriage to childbirth and childcare, and make Gangdong a truly family-friendly district.”
