US Covid-19 Case Rate vs. Population Density

Above, average daily number of Covid-19 cases diagnosed last month per 100,000 inhabitants; below, population density. The extent to which these are mirror images is quite remarkable. I suppose that's partly because places like New York and Los Angeles had many more cases in the first wave. But you have to think that given how spread out people are in most of Alaska, even a little bit of caution could easily have given them the lowest rate.
