You see it all the time, on all the news channels: brightly coloured maps showing how many cases each state has. New York, California, Texas and Florida are dark red, because they have so many cases.
But that's not a particularly meaningful bit of information. Of course those states have the most cases: they have the most people.
A better map would show the infestation of corona virus as a percentage of population. On that map, the dark-red states would be Louisiana, Arizona, Florida, Mississippi, New York, New Jersey, Alabama and Georgia; each of those states has more than 2,000 cases per 100,000 people.
Close behind would be South Carolina, Rhode Island, DC, Nevada, Tennessee, Massachusetts, Texas, Arkanss, Delaware, Maryland, Iowa, and Illinois, each with more than 1,500 cases per 100,000 people.
California would be in the middle group, along with Nebraska, Connecticut, Idaho, Utah, North Carolina, Virginia, Oklahoma, Indiana, South Dakota, Minnesota, New Mexico, Kansas and Wisconsin, each with 1,000 to 1,499 cases per 100,000.
All this shouldn't make the authorities, or the people, in Texas and California feel much better about the whole thing, but it would give a more meaningful sense of how bad things are in various states.
If you want to know where your state stands, go to https://www.cnn.com/interactive/2020/health/coronavirus-us-maps-and-cases/ and click the column heading "...per 100,000 people." Bear in mind, too, that the great majority of cases in the northeast -- New England, New York and New Jersey -- are cases that came up in the early stages of the pandemic, before we knew as much about how to stop the spread.
An even more useful map would be one that showed the states' relationship based on positivity rates. Positivity rates are the best indicator of how fast the virus is spreading in an area. The worst places on that map would be Mississippi (21%), Texas (19%), Florida (17.5%), Alabama (17%) and Nevada (16%), Washington (15%) and Idaho (also 15%). You can find these statistics at https://coronavirus.jhu.edu/testing/testing-positivity, but I don't know where you can find an actual map to illustrate these statistics in a quickly-understandable way.
