The city maps on the NYC Data neighborhood page allow users to view neighborhood areas and click on them to view data directly from the US Census Bureau. There is a map for PUMAs (census statistical areas that have 100k people and are similar in size and shape to community districts) and a map for ZCTAs (ZIP Code Tabulation Areas, which represent USPS ZIP Codes that have a geographic area). The PUMA maps point to the latest 3-year profiles from the American Community Survey (ACS), and the ZCTA maps point to profiles from the 2010 Census and the latest 5-year ACS dataset.
Both maps have just been updated to point to 2013 data that was recently released. They can be viewed within the guide, but can be navigated more easily if you hit the full screen button that’s embedded in the map.
Previously, the maps were overlaid on a Google Maps basemap. Unfortunately Google decided to deprecate the ability for people to overlay KML files stored on webservers over their maps. The alternatives they offer are completely unsatisfactory. So, we are now using a free service from CartoDB, a web-mapping service headquartered right here in the Flatiron district, as our new platform. Many thanks go to Data Services CA Rachel Weinberg for researching and experimenting with CartoDB so we could keep this service up and running!
