Average Annual Income by Residential Area in South Korea

Average annual income refers to the total yearly earnings of residents in a specific area divided by the number of individuals. It provides a reference point for comparing income levels across different regions based on where people live.

The residential-area-based income ranking in South Korea shows that high average incomes are concentrated in Seoul’s core districts and surrounding metropolitan cities. Seocho-gu leads with an average income of 87.27 million KRW, followed closely by Gangnam-gu (86.49 million KRW) and Yongsan-gu (79.26 million KRW). These areas are known for a high density of professionals and high-income households.

Outside Seoul, Gwacheon in Gyeonggi Province records 68.32 million KRW, placing fourth. Other Gyeonggi cities such as Seongnam (58.78 million KRW), Yongin (53.97 million KRW), and Suwon (49.25 million KRW) are also among the top cities.

In Ulsan, Buk-gu (53.43 million KRW) and Nam-gu (52.72 million KRW) show relatively high average incomes compared to other regions. Among major cities, Suseong-gu in Daegu (52.51 million KRW), Yeonsu-gu in Incheon (52.43 million KRW), and Yuseong-gu in Daejeon (51.30 million KRW) also rank high.

Seoul’s other notable districts include Songpa-gu (60.27 million KRW), Seongdong-gu (57.35 million KRW), and Mapo-gu (56.26 million KRW). Income differences across districts may reflect differences in occupational distribution, resident demographics, and housing prices.
