Cases
Ln(# workers + 1)	0.023*a (0.006)b	0.040* (0.005)	0.014* (0.006)	0.023* (0.003)

R2	0.34	0.34	0.34	0.34

Note: Each column reports the results of a linear regression in which the dependent variable is either the natural log of the cumulative number of COVID-19 cases or deaths divided by population on March 31, 2021(plus 0.001 for cases or 0.00001 for deaths to include counties that have no COVID-19 cases). Regressions also include state fixed effects.
