Top 11 counties (not 10 because I wanted to include LA):


bronx 23426
brooklyn 28183
manhattan 13740
queens 33616
cook 16323
nassau 25250
suffolk 22691
westchester 20191
wayne 12209
bergen 10426
LA 10047


But look what happens wen you normalize by population:

Cases per million population:

westchester 20880
nassau 18607
bronx 16520
suffolk 15363
queens 14789
bergen 11184
brooklyn 11126
manhattan 8435
wayne 6981
cook 3170
LA 1001

I would infer that the difference by county might even greater than this shows.

In New York, the confirmed cases represent about 40% of the tests done. California, about 12% of the test come back positive.

My guess would be that this means that New York is applying a tougher risk assessment to see who gets the test. Possibly meaning that if they were able to test as many of the moderate risk profile cases as California, it would have even more confirmed cases?

The County I live in in Nevada looks a lot like Los Angeles. About a thousand confirmed cases per million population, and about 12% of the tests coming back positive.
