Special Release - Census Blocks with Population and Housing Counts

We have produced a special version of shapefiles that incorporate the 2010 Census block geography and the 2010 Census population and housing unit counts. These shapefiles are available at the state level for the 50 states and the District of Columbia. At this time these shapefiles are not available for Puerto Rico or the Island areas.

These shapefiles were created for a special project so they do not contain all of the attributes of the TIGER/Line Shapefiles but contain the information necessary to identify the census blocks.
