in US Counties: Does Minority Racial Concentration Matter? Am J Public
Health 92(1): 99-104.
This study examined (1) the relationship between income inequality
and mortality among all counties in the contiguous United States to
ascertain whether the relationships found for states and metropolitan
areas extend to smaller geographic units and (2) the influence of minority
racial concentration on the inequality-mortality linkage. Methods. This
county-level ecologic analysis used data from the Compressed Mortality
Files and the US Census. Weighted least squares regression models of age-,
sex-, and race-adjusted county mortality rates were estimated to examine
the additive and interactive effects of income inequality and minority
racial concentration. Results. Higher income inequality at the county
level was significantly associated with higher total mortality. Higher
minority racial concentration also was significantly related to higher
mortality and interacted with income inequality. Conclusions. The
relationship between income inequality and mortality is robust for
counties in the United States. Minority concentration interacts with
income inequality, resulting in higher mortality in counties with low
inequality and a high percentage of Blacks than in counties with high
inequality and a high percentage of Blacks.
