You wanna walk that back?? New York City is always referred to as having a population of 8+million people.
But those numbers come from considering all of the "boroughs" that aggregated create what we refer to as New York City: Manhattan, the Bronx, Brooklyn, Queens, and Staten Island.
Per the JHU Covid tracker, these are the deaths to date per locale, ranked by the hardest hit counties in the state:
#1 - Queens County (Queens): 3,002 Deaths
#2 - Kings County (Brooklyn): 2,929 Deaths
#3 - Bronx (The Bronx): 2,207 Deaths
#6 - New York (New York): 1,316 Deaths
#16 - Richmond (Staten Island): 485 Deaths
New York City Total: 9,939 Deaths
New York State has 20,792 Deaths
48% of the states deaths come from New York City. Not the suburbs like Westchester County, Rockland, Nassau County, Suffolk. Further, countless commute from CT (Fairfield primarily and New Jersey (320,000 daily).
Further, 1.6 million are estimated to commute into the city daily, not the arbitrary 3.1 Million you use:

320,000 of those come from New Jersey.
Likely you've never been to Manhattan. You're speaking about that which you know little about. Stick to what you know. Limited list of topics, I realize.
