Does anyone know when data will be released on poverty, household incomes, etc. at the municipal level?

Hi Kendis,
The formatting for the records in the UA TIGER files are a little
different than the previous release so you won't get the correct results
using the TIGER tools in Arc 8.
If you do convert the UA TIGER files with ArcTools you will notice that
the first 4 of the 5 digits for the 2000 UA Code end up in field UA90
and last digit in UR90.
You can see why this happens if you compare the formatting of the
ArcInfo result for Record Type A to the Census Documentation for Record
Type A (Chapter 6, p.12).
In other words UA90+UR90=UA.
So, you can get a look at the Urban Areas if you relate Record Type A
to the Census Geography using CENPOLID and concatenate fields UA90 and
UR90.
But I personally am going to hold off doing much more work with the UA
TIGER files until ESRI updates the conversion tools.
I'm sure there are other formatting changes that I'm not aware of.

So, if you are using Arcview 3.2 and ArcInfo 8.1 and are not able to
buy a
third party software, a person can't process these UA boundaries off
the
Census site?

The SF 1 Data CDs, available by state for $195 each, have the full SF 1
tables for each summary level down to Census blocks. The State Data CDs,
also available by state for $195 each, have geographic files for all of the
summary levels within a state, down to Census blocks, plus other geographic
files such as streets.
Maptitude and TransCAD come with nationwide geographic files down to Census
tracts, and the demographic profile for SF 1 for each of those summary
levels. For more information on geographic and Census 2000 demographic data
available from Caliper Corporation, visit (http://www.caliper.com/ovudata.htm).

Thanks to everyone who responded. It looks like the converter I used
is the problem. I will have to follow up with one of the alternatives
many of you suggested.
I found the TIGER Reader script by clicking ArcScript on the ESRI main
page and then running a search for "tiger" and narrowing the search to
the Avenue language. The URL line from the search is

I've used the following method which uses some custom programs written by
Warren Glimpse of Proxityone (www.proximityone.com)
Here's a breif description:
Though there are many ways to develop such a file, here is one method. The
UAC and geocode hierarchy to get to the block level are contained in the
composite of Census 2000 UA TIGER/Line files 1, A, and I. The appropriate
TIGER/Line files can be downloaded from the Census server and processed with
the Proximity TGR2DBF software creating a dbase structured version for these
three TLFs. Next use TGR2DBF to create a census block-to-UA/UC code
equivalency file (BLKUA.DBF). Next acquire the county by census block
shapefile(s) from the Proximity map files website. Use the Proximity Cen2Shp
software to merge the UA/UC code from the BLKUA.DBF into the county by block
shapefile dbf. The augmented shapefile is now ready to support a display (or
data link) of census blocks by user selected UA/UC. View the results of this
process for the Lawrence, Kansas metropolitan area at

I am having similar issues. I converted the files using the 2000 Tiger conversion tool in the ArcToolbox in Arc8. When I do this, the resulting files do not contain the UA field. I placed a call to the Census Bureau's geography department today, and was told that they have already heard of this happening and they suspect that it is due to the converter. They were not able to offer any help, but told me to go back to the software vendor. I am now trying to find someone at ESRI who can answer some questions. Has anyone else found a way around this?

Maybe someone can tell me what I am missing here.
I have downloaded the data and converted it in Arc View 3.2a with a Tiger Reader from the ESRI web site. But the closest thing to an "Urban Area" for 2000 is the "Transportation Planning Area."
Any help?

This is probably a Bob LaMacchia question (Census Geography) but I'll post it to the CTPP-News since it may be of interest to many MPOs.
Are the "Urban Cluster" boundaries included on the soon-to-be-released UA/TIGER files?
The Bureau's web page (below) says yes, but I can't find a variable field for urban clusters in the PDF-formatted "record layout."
http://www.census.gov/geo/www/tiger/tiger2k/ua_struc.html
Or, are urban clusters and urbanized areas use the same "UA" code on the TIGER files? (And, if they use the same UA codes, is there any other indicator to use to separate by UAs from my UCs? I've got 13 urbanized areas and an additional 12 urban clusters in my region, which is manageable if I want a manually separate urbanized area versus urban cluster GIS layers....)
(Urban clusters are smaller urban populations of 1,000-49,999 population, and apparently > 1000 persons per square mile. They include such places as Calistoga and Half Moon Bay in the Bay Area, and many of our California state prisons....)
(WARNING: ESRI's web site www.geographynetwork.com DOES have TIGER 2000 data files in SHP format, but the "urban areas" that are included on their site are the 1990 URBANIZED AREAS, not the 2000 UAs!!! If ESRI staff are monitoring this listserv, you may want to clarify what is currently available, and when the 2000 UAs will be available on geographynetwork.com.)
Thanks in advance!
