In FLA 20k positive tests in a particular day, as an example. Or pick CA if you prefer and use that number of positive tests. Out of how many tests done that day? Perhaps that number is somewhere and I just dont see it.
Before any kind of comparison or breakdown that should be the first question to answer. Positives compared to population, the usual graph various people like to show, is important as additional information. But lets say, for argument sake, that the 20k in florida that day was among 40k tests (1 in 2 chance of a positive). Then lets say 5k in California but out of 5k tests. Sure 1/4 as many as Florida. But every test would be positive. Thats a pretty fundamental difference before anything else.
If you want a totally unscientific extrapolation, 1/2 of the 20+ million in Florida are infected, assuming every person was tested today. Whereas California with its 40 million people is in deep... well.... pretty deep.
