Though some of us actually grew up here—promise—we will admit that New York City is, in reality, a city of newcomers where at any moment, another hundred people just got off of the train. But where do they all go? Everyone has the neighborhoods they like to joke the transplants all move to—*cough* Murray Hell *cough*—but is that really true? OH, there's a map for that.
Yup, the fine folks at WNYC have gone and mapped out Census data from the last few years to figure out where the newest New Yorkers are living. Of course the data only counts people moving to the city from other states or abroad (so no data on where the unending supply of Long Islanders all are living). And you'll want to look closely because just because something is dark red doesn't mean it has a HUGE transplant population but it is very cool nonetheless:
So, moral of the map? New New Yorkers are moving into pretty much exactly the areas you think they are—well, new New Yorkers who answer Census questions, which not everyone likes to do! Think "hip" downtown places, doorman areas and new the West Side.
But just because they move there doesn't mean they stay there. Presumably after they spend a few years in "safe" Manhattan hoods they then realize like everybody else that that the rent is too damn high and move to the outer boroughs.
