Since a few weeks, I report the raw number of COVID-19 cases in Maryland counties. If this gives an idea of the cumulative number of cases – which is interesting – it doesn’t reflect the fact that some counties have more inhabitants than others. That’s why I plotted below the number of COVID-19 cases adjusted for the population:
Today (May 11, 2020), in terms of absolute number of cases, Prince Georges, Montgomery and Baltimore County are the top 3 counties. In terms of confirmed cases per 100,000 population, the top 3 counties are Prince Georges, Montgomery and Wicomico (due to a recent surge in cases).
|Rank on May 11, 2020||Absolute # of COVID-19 cases||COVID-19 cases per 100,000 population|
|1||Prince Georges (9,687)||Prince Georges (1,057)|
|2||Montgomery (6,909)||Montgomery (656)|
|3||Baltimore County (3,948)||Wicomico (649)|
|4||Baltimore City (3353)||Kent (555)|
|5||Anne Arundel (2492)||Baltimore City (544)|
This is a lot given that, today, the average for Maryland is 401/100,000 (source: CDC) and the average for the US is 552/100,000 (source: OurWorldInData).

As usual, you’ll find other graphs on my page about COVID-19 in Maryland and the data, code and figures are on Github.
