Description:

Abstract:

The Census Blocks for the 2010 US Census. These boundary files are derived from the US Census Bureau's TIGER project and have been geographically modified to fit the New York City base map. Because some census blocks are under water not all census blocks are contained in this file, only census blocks that are partially or totally located on land have been mapped in this file.

Purpose:

These districts were created by the Department of City Planning to aid city agencies in administering public services.

Supplemental Information:

The official boundaries of Census Blocks include areas under water. Users requiring these boundaries should use nycb2010wi instead.
