User Note 1: Topological Faces (Polygons with all Geocodes) Shapefiles Replaced for 304 Counties on September 13, 2013
On September 13, 2013, the Topological Faces (Polygons with all Geocodes) Shapefiles were replaced on the FTP site for 304 counties. In files downloaded before this date, there are TFID records that are missing values for the BLOCKCE and possibly the SUFFIX1CE fields. The errors occur in areas where there have been county boundary adjustments since 2010. The affected counties are listed in the 2013 Topological Faces Corrected Counties text file.
