As Seoul's population shrinks, 'Gangnam 4 districts' grow, fueling conservatism

The demographic shifts within Seoul reveal a widening chasm between its affluent southern districts and the rest of the city, a trend that appears to be reshaping the political landscape. While the overall population of Seoul has declined, the 'Gangnam 4 districts'—Gangnam, Seocho, Songpa, and Gangdong—have experienced a notable influx of residents, increasing their share of the city's total population. This concentration is not merely a matter of housing; it reflects a complex interplay of factors including superior educational facilities, desirable living environments, and a high density of lucrative job opportunities.

Analysis of recent statistics shows that these four districts are not only attracting new residents but are also experiencing significant growth in household income, with a substantial percentage of households earning over 100 million won annually. This economic prosperity, particularly when contrasted with the lower average incomes in other parts of Seoul, fuels a growing asset gap. The ruling Democratic Party's formation of a special committee for the Gangnam 4 districts underscores the political significance of this demographic and economic concentration, indicating a strategic effort to court voters in these traditionally conservative strongholds.

The political implications are becoming increasingly apparent. Data suggests a discernible shift towards conservatism in Seoul, with a growing number of residents identifying as conservative compared to a decade ago. This trend is particularly significant given that past presidential elections have seen candidates struggle to win in these affluent southern districts. The narrative emerging from Seoul is one of increasing political polarization, driven by economic disparities and the unique advantages offered by the Gangnam 4 districts, which are becoming a self-contained hub of wealth, opportunity, and, it seems, conservative political sentiment.
