This is probably the first time a literary magazine has won our Map of the Day prize! The Morning News put up a nice set of maps by Dorothy Gambrell measuring the bohemianess of various neighborhoods in NYC. The formula she used:

[(% of persons 18–24 with some college or associate degree or higher) + 7(% of persons 25+ with a bachelors degree or higher)] / [median household income in dollars]

All data was taken from the 2000 census, so some recently popular neighborhoods like Prospect Heights and East Crackden Williamsburg might not be accurately depicted. Read their background interview with Dorothy-- in it she identifies the neighborhood that's most crawling with BoHo types-- drumroll please.... it's Morningside Heights!
