The Pew article The Changing Geography of COVID-19 in the U.S. by Bradley Jones and Jocelyn Kiley provides data about the geographic impact of COVID-19:
Early in the course of the pandemic, the health impacts were felt most severely in dense urban centers. From March to May, congressional districts in the most urbanized parts of the country were experiencing about five times as many deaths on average compared with those in the least dense parts of the country, and in some places this disparity was much larger.
However, by the summertime the urban-rural split had largely disappeared, and over the last several months, those districts with small shares of residents in densely populated places have been experiencing twice as many deaths as those in the parts of the country where all or nearly all residents live in urban neighborhoods.
The article has an interactive graphic of the U.S. with COVID-19 deaths by congressional district over time, along with a few other tables and graphs. There is also a longer report that can be downloaded.
