And as you get closer to the bottom of the list, the numbers needed to move places gets tigher and knocks a few off the list
Unfortunately, since 2020, the population of all New York City counties has taken a nose dive. In fact, I sorted the top 50 counties by population loss as a percentage of the population. The top 4 were all New York City!
1) Bronx -6%
2) Manhattan -6%
3) Brooklyn -5%
4) Queens -5%
Biggest gainer was Collin County, Texas (+8%) which is a suburb of Dallas.
