This map shows the census tracts (in black) where about 67% of the USA population lives (2010 data) overlaid onto the NYTimes map of COVID19 cases (3/22/2020). Sorry about the problem with northwest Washington state!
The implication is obvious, and should have been clear to everyone for a while now: Two thirds of the population of the USA is at immediate risk of infection from the virus. If unconstrained, that’s more than 200 million cases, with a mortality rate somewhere between 0.1% and 1.0%. That’s a lot of people at risk of death, up to two million.
Let’s hope that the increasing number of areas on lock-down slow the spread and reduce the number!
Be well, readers. (Both of you!)
