The distribution of mortality in the United States: the effects of income (inequality), social capital, and race.
This article examines how absolute and relative income levels, social capital, and racial/ethnic composition interact to explain variation in age-adjusted mortality rates across the 48 contiguous U.S. states. Our data showed that social capital had a powerful, negative effect on age-adjusted mortality rates--higher social capital states had lower age-adjusted mortality rates. After controlling for other variables, median income moderately related to mortality, but unexpectedly three measures of inequality did not. Finally, states' percent African American positively related to mortality, though indirectly and mediated entirely by social capital. In contrast, the strong negative effect of percent Hispanic/Latino on mortality was partially suppressed by its negative association with social capital. Our understanding of the substantial impact of social conditions on mortality can help inform public policies and actions that may foster healthier and longer lives.
