As requested by @ASlavitt, here are more or less comparable pneumonia mortality numbers for Florida, Georgia and Texas (cc @Noahpinion, @JamesSurowiecki) 
I used weeks 4 through 19 for comparison with past years because, while there is week 20 data available on CDC FluView for this years, it's pretty incomplete gis.cdc.gov/grasp/fluview/…
Florida and Georgia have definitely seen big increases in pneumonia deaths, but not as big as in the (now-deleted) @ASlavitt tweet that inspired this. And most if not all of that increase appears to be counted under the CDC's Covid death totals too cdc.gov/nchs/nvss/vsrr…
This whole thing appears to have started with somebody on Reddit attempting entirely in good faith to make a comparison between the pneumonia death toll reported on the CDC Covid site and that from past years in the CDC Underlying Causes of Death database ...
… but for reasons that I don't entirely understand (but am willing to trust @lymanstoneky on) the methodologies used in counting deaths are different and the numbers not comparable.
So no, doesn't seem to be any hidden explosion of Covid-19 deaths in Florida. Overall mortality in the state since the last week in January is just 101% of the norm, which compares with 129% in New York (231% in NYC), 150% in NJ, 126% Michigan ... cdc.gov/nchs/nvss/vsrr…
Oh, and look, here was @lymanstoneky making similar points in the middle of the night (our night, not his night)
Oh, but now it's time to fact check the fact checker! These CDC "percent of expected deaths" numbers that I cited here turn out to be … problematic
Those percentages don't account for incomplete data from recent weeks. The CDC is reports here that Connecticut deaths from all causes are only 51% of norm. But if you download the spreadsheet it's clear the CT data is incomplete going back to early March cdc.gov/nchs/nvss/vsrr…
A reader ran the numbers for Florida ignoring the two most recent weeks and got a death toll 108% of normal, or about 3,500 excess deaths. Florida has reported 2,364 Covid deaths. That's probably an undercount! But I suspect most of it was early on when tests were in short supply
According to the CDC, no one has died in Connecticut from any cause since May 2 (meaning the data are obviously incomplete)
