There are other densely populated areas in the US, namely LA Metropolitan Area, South Florida metropolitan Area and Boston metropolitan area. E.g. NYC area is 26,403 people per mile^2, and Boston metropolitan area is 13,841 people per mile^2. But NYC seems to be doing much worse than 2 times worse than Boston. Maybe it's because NYC population is older? E.g. in Boston 52% of deaths are from LTC facilities (yesterday's data), which seems to imply virus hasn't penetrated into community that much.

I don't think you should be expecting people per square mile to scale 1:1 with mortality rate anyhow. I would guess putting twice as many people within a square would result in the virus spreading an order of magnitude faster. Similar to how increasing infection radius in an SIR model increases spread by much more.
