Spatial inequality is understood as a function of geography or administrative planning, but its relation to ethnic segregation is less well understood. This column analyses this relationship using regional data for 71 countries with different levels of economic development. The degree of spatial concentration of ethnic groups is a robust and highly significant predictor of within-country income disparities. More ethnically segregated countries experience higher levels of spatial inequality and are thus more prone to conflict.
