I understand, but if Brooklyn is the richest city, then what is its overall GDP, both nominal and PPP? I am just curious to see where it ranks compared to other powerhouses like NYC, London, etc.
Also, what is the national wealth of New England? If you don't know what that is, here's a link:https://en.wikipedia.org/wiki/National_wealth
Again, I don't track economic data at that level as complex as I do elsewhere.
I also noted that Brooklyn is the economic and financial centre. Not that it was the richest. Considering that it's part of the Tri-City Region, it makes it kinda impossible to parse out relevant economic data from Brooklyn vis a vie New York City.
As for wealth, I calculated the Household net worth of New England, not the total national wealth.
Household net worth is £26.842 trillion. This translates to $32.930 trillion.
