And what the hell - here's one more map of Gotham. This one, from Curbed, shows property prices in New York City per square foot.
Notice that three-fourths of Manhattan is essentially uninhabitable by any sort of normal person. Note too, though, that these prices are from 2006, before the real estate bubble popped. And Wall Street bankers are not doing quite so well these days. It'd be interesting to see what the map would look like today.
