A worthwhile question is whether NYC had higher fatality rates than it otherwise would because of overwhelmed hospitals. One indication could be if the ratio of deaths to hospitalizations is high, which might indicate i) people avoiding hospitals or ii) not getting adequate care.
Nationally this ratio is 0.19 in the average state to have recently updated its cumulative hospitalization data, with a standard deviation of +/- 0.06. New York state is at 0.25 which is one SD above the mean, so it's definitely on the high side but not some crazy outlier.
In New York City, the ratio is 0.26 using confirmed deaths, although it jumps up to 0.39 if you use the city's count of *probable* deaths. It's not obvious to me which count to prefer here (how are other states/cities handling cases that NYC would consider probable deaths?).
No super pithy, definitive conclusion. Just think this sort of data may be worth looking at in a less quick-and-dirty fashion than I did here.
