The Census Bureau finished its roll-out of the latest American Community Survey (ACS) estimates in December. I’ve updated the neighborhoods tab of the NYC Data guide to point to the latest summary profiles:
- Google map of NYC ZCTAs (ZIP Code Tabulation Areas) points to the latest five-year estimates: 2008-2012
- Google map of NYC PUMAs (statistical areas with 100k people that approximate groups of neighborhoods) points to the latest three-year estimates: 2010-2012
- Links for the city as a whole and each individual borough / county point to the latest one-year estimates: 2012
The PUMA-level data for the 2012 ACS uses new PUMA boundaries that were redrawn for the 2010 Census; previous editions of the ACS (from 2011 back) used 2000 Census boundaries. While the boundaries are only slightly different, the biggest change is that the Census has assigned names to the PUMAs based on local government input; previously the PUMAs were numbered but not officially named. The Google Map has been updated to reflect this change, and Joe Paccione has created a series of static PDF maps (avaliable on the same page under the link “PUMA Maps”) that depict the PUMAs with their numbers and new names.
