The world needs both lumpers and splitters!I had to look that up! You taught me a new terminology. I'm a pretty solid lumper in that context. I have a background in statistical thermodynamics - canonical ensembles all the way - so that's my inherent bias.
In the context of answering your particular thesis, I was curious how you'd parse it, just to know more about you.
I was being a little glib and lumping like crazy, because Florida is as Republican as they come and not among the poorest states, Blacks weren't the majority of COVID-19 deaths in Florida, and Florida has a poor record (14th worst) w/regard to per capita COVID-19 deaths.
Historical time series of race and ethnicity data in Florida.
As of December 2022, Mississippi had the highest COVID death rate in the U.S., with 439 deaths per 100,000 population. Hawaii had the lowest death rate.
However, your thesis about poverty is right even in Florida:
Poor counties nationwide including FL had higher COVID death rates compared to wealthier counties - Florida Phoenix
This report shows why we must have a moral meeting in the nation’s capital.
Not going to try to find someone who's parsed voting habits by race in poor counties in Florida, though that would likely address the chicken-or-egg question.
