Last week , the 2000 boundary files part of the web site posted a file
ua99_d00. It appears to be a generalized version of the urban areas. Was
this a previous version or does this represent the official 2000 Census
urban areas? It is a different file name than in your email.

determination of Urbanized Area (UA) and Urban Cluster (UC) boundaries.
are aware of some users having difficulties finding up-to-date
applications to develop their own UA/UC boundaries from the UA Census
TIGER/Line* files. The boundaries in these files are an exact match of
boundary details found in the UA Census 2000 TIGER/Line files. The
files were extracted from the Census Bureau's TIGER geographic database
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
(over 31MB) and is nationwide in coverage. We do not have this file
