Economic segregation refers to the uneven spatial distribution of individuals or households according to their economic resources, particularly income, wealth, or socioeconomic status, resulting in the geographic concentration of economically similar groups and the separation of groups with different resource levels ^[1][2]. It is commonly examined through residential patterns, where housing markets, household preferences, land-use regulations, and differences in purchasing power influence the sorting of populations across neighborhoods ^[1][3]. Economic segregation differs from economic inequality, which describes disparities in resource distribution without necessarily considering their geographical arrangement. It can be measured using spatial segregation indices that capture the unevenness, isolation, or clustering of income groups across geographical units and spatial scales ^[2][4].
