Interestingly enough, very few Nuyoricans and Dominican Yorks choose South Florida (Miami-Dade/Broward/Palm Beach), due to the fact that its become an expensive part of that state. The Jewish migration from New York/New Jersey to South Florida (especially Palm Beach, North Broward, and even portions of coastal Dade) continues, albeit largely of the upper Middle Class to wealthy, to say nothing of wealthy South Americans.
I was aware that a lot of Puerto Ricans (not just from NY, also from PR itself) had moved to the Lehigh Valley over the past decade or two, but wasn't aware of the Poconos being a magnet as well.
The reverse migration of Nuyoricans to the Island is quite different from that of Dominicans, since most Nuyoricans who move to PR don't do it to retire, they move to PR to work under less stressful conditions and nicer weather.
