A big shout-out to the National Investigative Team at Gray Television, who is also tracking positive COVID-19 tests per 100,000 residents on a local level—county by county all across the U.S.A.—complete with a beautiful interactive map. The team makes it so much easier for me to compile data and continue to track COVID-19 prevalence among U.S. largest cities (metropolitan area). See below.
