By what set of conditions are the racial disparities in SARS-CoV-2 infection rates reduced? Evidence suggests that disparities in social, economic, and many other conditions among races leads to significant differences in SARS-CoV-2 infection rates between black and white populations. We found that the proportion of green spaces in a county was negatively related to differences between SARS-CoV-2 infection rates: The greater the proportion of green space, the less black-white disparity in infection rates. We posit five core mechanisms and one circumstantial mechanism to interpret why a high ratio of green spaces at the county scale is associated with a lower racial disparity in SARS-CoV-2 infection rates.
