An interesting, although intuitively straight forward note on the determinants of Covid19 deaths: https://twitter.com/youyanggu/status/1407418434955005955.
As Youyang Gu @youyanggu states, "I believe income inequality is the single best predictor of total Covid deaths in the US. Not income, but income *inequality*. The R^2 is surprisingly high: 0.35."https://github.com/jsill/usstatecovidanalysis/blob/main/usStateCovidAnalysis.pdf), but the conclusion seems to be qualitatively robust.
