| Abstract |
This study examined the spatial relationship between the density of underground housing and socio·economic polarization in the Seoul
Metropolitan Area. At the administrative-dong level (n = 1,137), we analyzed how underground housing density correlates with average
housing sale prices and concentrations of vulnerable groups (elderly and National Basic Livelihood Security beneficiaries). Using Ministry of
Land, Infrastructure and Transport transaction data alongside KOSIS and other public data, we mapped each variable’s clustering and applied
Global, Local, and Bivariate Moran’s I for spatial autocorrelation analysis. Key findings are as follows. At first, there is a significant positive
spatial correlation between underground housing and vulnerable population densities, reaffirming these dwellings as typical “vulnerable
housing.” Next, a weak but positive spatial correlation with sale prices was observed, suggesting that factors such as commercial and
transport accessibility?not just low cost?shape their distribution. Finally, there is the potential for a “housing-cost paradox,” whereby
vulnerable residents still bear high housing burdens tied to market rates. We recommend tailored, location-specific housing welfare policies
that reflect this spatial heterogeneity. |
