> Florida has way more older people per Capita which are more vulnerable to Covid.
> So that accounts for the deaths.
No, it doesn't. Florida has less than a time and a half the 65+ population share that California has; while it might account for a higher death rate, it doesn't account for a more than double death rate, and it especially doesn’t explain an even greater discrepancy in the death:case rate than the death:population rate.
> But why are new cases so low in a place with very few vaccinated and no Covid restrictions?
Because COVID precautions (vaccination, voluntary testing without hospitalization, etc.) are mutually correlated, and so Florida has less likelihood of detecting cases that don't involve hospitalization; it also means cases that eventually require hospitalization are detected later with less early intervention. Which explains why Florida has, compared to other states, a low detected case rate, but a middle of the road hospitalization rate, and a very high death rate.
