I'm not convinced that density is a major factor in covid mortality as outdoor transmission is minimal, and the virus was able to spread effectively throughout the population even in low density areas. (I could be convinced by good data, but I haven't seen any on this) Also density measurement is hard. Does Utah count as "dense?" If you look at pop density by state it is near the bottom, but almost all of that population is crammed into a small area near Salt Lake City. Similar situation in Nevada.
