Race, Income, and Environmental Inequality in the United States

Abstract

This article asks whether the relationship between neighborhood and household income levels and neighborhood hazard levels varies according to neighborhood and household racial composition. Using a national, census tract-level data set, the authors find that black, white, and Hispanic households with similar incomes live in neighborhoods of dissimilar environmental quality, that the association between neighborhood and household income levels and neighborhood hazard levels varies according to neighborhood and household racial composition, and that increases in neighborhood and household income levels are more strongly associated with declining hazard levels in black neighborhoods and households than in white neighborhoods and households. These findings contradict Wilson's claim that the significance of race has declined in the modern industrial period and demonstrate that environmental racial inequality is not the product of racial income inequality. In addition, these findings suggest that the impact of higher incomes on black/white proximity to environmental hazards has less to do with increases in white geographic mobility (relative to black geographic mobility) than with the ability of higher income blacks to escape the highly polluted, disorganized, and deteriorated neighborhoods to which so many low-income blacks are confined.
