A cross-sectional ecologic analysis using US county-level data found that counties with higher income inequality and a higher proportion of Black or Hispanic residents had higher COVID-19 incidence and mortality. Each 1% increase in county-level income inequality, proportion of Black residents, and proportion of Hispanic residents corresponded to 2%, 1.9%, and 2.4% higher incidence and 3%, 2.6%, and 1.9% higher mortality, respectively. No state-level political characteristics were associated with incidence or mortality. Incidence was on average 32% lower in counties in states with Medicaid expansion than those without.
