Exploring racial disparities in CHD mortality between blacks and whites across the United States: A geographically weighted regression approach

► We examine spatial heterogeneity in black-white differences in CHD mortality across the US. ► We also assess the contributions of poverty and segregation. ► We find significant spatial heterogeneity in black-white differences in CHD mortality across the US. ► Poverty and segregation explain at least some of this spatial heterogeneity. ► Indicating these disparities are not “natural”, but are malleable and context dependent.
