City population: 8.3M/750k -> one order of magnitude
City density: 28k/8400 -> less than one order of magnitude
This is not what one imagines when one encounters the sentence fragment "Like many orders of magnitude difference."
[EDIT:] Normally technical correctness is appreciated? If anyone here really thinks that New York has done a better job dealing with the pandemic than Washington State, I would love to see the reasoning. ISTM this argument from population proves too much; why can't it be invoked anytime New York's performance lags other states?
Beyond an order of magnitude in population, you have the cultural differences: Low usage of public transportation (compared to NYC), strict observation of social norms, comparatively high number of folks who can work from home, etc.
