This “race and ethnicity” mapping tool published by the NY Times, overlay on a Google Map, collects census data spanning from 2005-09. It reveals some interesting reflections of the 5 boroughs: Roosevelt Island is pretty damned mixed; there’s more red in Flushing than in Chinatown; one side of Prospect Park is solid green, the other solid blue; there is one lone red and one lone yellow dot in Breezy Point, otherwise its all green; there are people living in Flushing Meadows-Corona Park, but not in Central Park; and, do any White people live in the Bronx?
