As many of you know, there was an error in the 1990 Urban/Rural indicator in the UA Census 2000 TIGER/Line files. We have recreated the files to correct for this error that affected 1094 counties. We will be uploading the corrected files to our Internet site by the end of May (by the end of next week). Check the page at:

We also will be making available from our web site a NATIONWIDE detailed UA/UC boundary file in ArcView Shapefile (.shp) format to facilitate the determination of Urbanized Area (UA) and Urban Cluster (UC) boundaries. We are aware of some users having difficulties finding up-to-date conversion applications to develop their own UA/UC boundaries from the UA Census 2000 TIGER/Line^® files. The boundaries in these files are an exact match of the boundary details found in the UA Census 2000 TIGER/Line files. The boundary files were extracted from the Census Bureau's TIGER geographic database for use various internal Census Bureau projects and have been made available here on an "as is" basis. Please note that this will be a very large file (over 31MB) and is nationwide in coverage. We do not have this file available at any other geographic level. This file will be available by the end of next week from the following page:
