NYC 2010 Tract Boundaries

Map of 2010 Census Tracts

There are so many places to get Census boundaries, but often for NYC, the layers from NYC Dept of City Planning BYTES of the Big Apple are the most detailed.

However, these boundaries do not contain fields to join with some of the more popular sources for Census variables, either for the the 2010 Decennial Census or the American Community Survey 5-year estimates.

It doesn’t take too much time to create the various fields, and as you can see in the examples, these are very similar with just a couple minor variations. The boundaries are available in the data catalog.

NYC Planning uses a seven character ID identifying tracts, the first digit is the borough ID and the remaining six are the Census Bureau defined tract ID which is good if joining to the tables created by NYC Planning only.

Example Borough ID Tract ID
1010400 1 010400

The Census Bureau uses an 11 character ID for joining with data from the Census Bureau American FactFinder or Social Explorer

Example State Code County Code Tract ID
36061010400 36 061 010400

NHGIS uses a 14 character ID

Example Prefix State ID County ID Tract ID
G3600610010400 G 360 0610 010400

Infoshare uses a 10 character ID

Example County ID Tract ID
0610104.00 061 0104.00

The 2010 Tract boundaries can be joined with data from

  • The 2010 Decennial Census
  • American Community Survey (ACS) 5-yr estimates
    (except ’05-’09 which uses the 2000 boundaries!)
