All the information for the map comes from the 2010 Census data which — among other things — seems to have reported several people living in Central Park and other weird places. It definitely makes for a cool visualisation of numbers so huge as to be generally unimaginable, and it’s also neat to see the crazy differences in population density. You can go explore the whole interactive, zoomable map over at its website. [Brian Martin-Anderson via Boing Boing]
