The combined results of the 5 boroughs of NYC had a swing towards former president Donald Trump of about 9 percentage points. However, the combined results of Hudson Union and Essex counties in New Jersey, right by New York City, only swung 3 points in that direction.

They seem to have similar non-white populations, foreign born populations, etc. Why did NYC swing towards Trump more than three nearby counties in New Jersey that seem similar demographically?
