Cartographic Boundary Shapefiles - Block Groups

The cartographic boundary files are simplified representations of selected geographic areas from the Census Bureauís MAF/TIGER geographic database. These boundary files are specifically designed for small scale thematic mapping.

Generalized boundary files are clipped to a simplified version of the U.S. outline. As a result, some off-shore areas may be excluded from the generalized files. For more details about these files, please see our Cartographic Boundary File Description page.

The 2013 Alabama block group zip file (cb_2013_01_bg_500k.zip) is missing the FGDC metadata file but includes metadata in the ISO format.
