Tri-state COVID-19 Cases per 100,000

Below is a tri-state map representing the number of COVID-19 cases per 100,000 people in each county, based on the numbers released yesterday (3/29/2020). Normalizing to population helps highlight areas with lower proportions of reported cases. The chart included on the map, shows each county with at least 500,000 and the current ratio. For example, the counties in Ohio around Cincinnati and Dayton show lower values than other large counties. There are many limitations to using this one data source, but it would be interesting to note if measures enacted in these areas are helping, if the virus spread is earlier in the cycle, or if there are testing limitations.


Based on the current data, the highest proportions are observed in the greater Philadelphia and Columbus metropolitan areas.
