Abstract
This study analysed the dimensions and patterns of spatial wage income inequality in Seoul from 2006 to 2018. A Theil decomposition was applied to National Health Insurance Service administrative big data of all Seoul residents. Three distinct dimensions of spatial wage inequality (‘regional wage income differences’, ‘within-regions income inequality’ and ‘between-regions income inequality’) were confirmed using factor analysis. A subsequent cluster analysis identified four major district patterns of wage inequality evolutions, including a pattern of triple ‘highs’ and another of triple ‘lows’ of average wage income, within-low-level administrative areas (dongs) inequality and between-dongs inequality. These dimensions and dynamic patterns of spatial income inequality in Seoul were interlinked and they co-evolved with the development of the city and community development policies.
