CUNY’s Center for Urban Research has posted a very cool block-level map comparing the 2000 and 2010 census. (Based on work I’ve been doing, the 2010 census for part of North Brooklyn is flat out wrong, so take the numbers with a big grain of salt – but CUNY’s map is a thing of beauty.)
Via Second Avenue Sagas, a visually compelling look at NYC transit statistics, complete with comparisons to systems in other cities (we stack up pretty well until you get to on-time performance).
