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.Keywords environmental inequality; environmental justice; environmental hazards; race Since the early 1990s, a growing number of researchers have attempted to determine whether environmental inequality exists in the United States (Bowen 2002;Brulle and Pellow 2005;Downey 2007). These researchers have focused much of their attention on three questions: Are racial minorities disproportionately burdened by environmental hazards? If so, is this because of their racial status or because minorities tend to have lower incomes than whites? And is neighborhood racial composition a stronger predictor than neighborhood income levels of neighborhood environmental hazard levels?We expand on this research, and on arguments set forth by Pulido (1996Pulido ( , 2000 and Downey (1998), by arguing that rather than comparing the predictive power of race and income, it would be more fruitful to ask whether these factors interact to produce environmentally inequitable outcomes. Thus, this study addresses questions such as the following: Does the association between neighborhood income levels and neighborhood hazard levels vary according to neighborhood racial composition? Are increases in neighborhood income levels more strongly associated with declining hazard levels in minority neighborhoods or white neighborhoods? Questions such as these have not been posed in prior environmental inequality research. Thus, this article extends prior research by (a) developing a theoretical explanation for why race and income should interact to produce environmentally inequitable outcomes and (b) testing neighborhood-and household-level hypotheses derived from this explanation.In order to test these hypotheses, w...
