Hi. I live in a small apartment in New York City.  It's very hot today!
Oh wow. That's expected judging by the fact that it is the most populous city in the United States.
And all the concrete and asphalt doesn't help either.  Yes it is the most densely populated city in the US for sure.
The figures are unbelievable, as at 2016 there were estimated 2016 population of 8,537,673 residents there
