Would anybody know what the deal was with the 2000 Census Traffic Analysis Zones?
I am working with CTPP 2000 Table 3 data. To do some spatial analysis, I turned to census boundary files for traffic analysis zones (http://www.census.gov/geo/www/cob/bdy_files.html). I quickly realized that 63 out 2639 zones for the Houston region are represented by 2+ non-adjacent polygons. Does this happen in other regions as well? Was this delineation done purposefully or perhaps these are simply errors stemming from TIGERLine 2000?
Any input will be much appreciated.
Thank you.

I thought I would share my notes from this conference. FCSM is held
every 2 years, and focuses on the many different surveys conducted by
federal agencies.
I have rarely attended, but this time, I gave a presentation about the
Transportation Secure Data Center
http://www.nrel.gov/vehiclesandfuels/secure_transportation_data.html ,
of which FHWA is the major sponsor. My attached notes do not cover my
(and Evan Burton's) presentation.
It is always interesting to see what people are trying, given that we
have so many of the same problems: cell-phone only households,
incentives, non-response, quality of response, disclosure avoidance,
etc. So, even if this post is not specifically about CTPP, there are
some tidbits related to ACS and census research at new university
centers.

I much appreciate the efforts by Elaine Murakami and others to help with the
AFF2 problem by providing the recent webinars in AFF2 and Data Ferret. I
must reluctantly confess that I am still struggling, and would like to know
how other members on the CTPP list serve are faring. Here are my conclusions
at the moment:
1. AFF2 is useful for obtaining pre-organized data profiles (despite
its clunky and counter-intuitive interface), but in my experience it's still
hard - even with the benefit of some training - to really drill down into
the kind of esoteric data I sometimes need.
2. Data Ferret is great for batches, like downloading a fair amount of
data for multiple geographies (like all BGs in a county, etc.) but I'm
having a hard time drilling down to the highly specific items I need.
My latest troubles involve trying to get employment/labor force
participation by age and sex for counties and/or my metro area from SF-3 in
Census 2000. I have been able, with the help of Data Ferret, to obtain the
table numbers (PCT 3500-PCT 3518), but Data Ferret can't seem to give me the
figures I need in a single download, and multiple downloads are proving
error-prone and troublesome. Searching the table numbers in AFF2 yields the
typically useless results. My search of the Missouri State Data Center site,
while much appreciated, hasn't yielded the results I need. My own State Data
Center (Arkansas) has some useful profiles, but again not as specific as I
need.
Does anyone else have tips?
I feel like I could use further webinars on Data Ferret or - just possibly -
AFF2, although I'm deeply suspicious of trying to make anything useful out
of AFF2, since results so far have been disappointing. The seminar on Data
Ferret back in December was helpful, but didn't have a lot of in-depth
training on large downloads, highly specific data needs, etc.
I'm deep in 'flyover country,' and hence there's a lack of training and
information exchange available. Surely others face the same issues. Does
anyone else want more web-based training, too?

The new urban area boundaries are not due out until the March / April timeframe. However, I heard this morning that the 2010 population estimates for the boundaries may have been released this week. Is there any truth to this and does anyone know where I might find the information?

This link was sent along to Elaine and me via Anne Morris co-chair of
the TRB Environmental Justice Committee from one of FHWA contacts. It
is goes to data from the Social Security Administration and lists
benefits by zip code, the number of individuals on Old-Age, Survivors,
and Disability Insurance program and the number of Disabled workers. It
might be helpful in trying to identify the disability needs for a
particular zip code or state or for that matter the number of
individuals over 65.

If you download the whole report the notes on what the data is all about
and where it comes from are right up front.
Anyone have experience using this data source? Anyone have a sense of
how it might line up with our traditional Census sources? Is it any good?

Does anyone know of a source of small (tract) area disability data other
than Census 2000?

Today, FHWA released an update of its information on Urban Area
Boundaries and release dates. Specifically FHWA's Office of Planning
has updated the “Census Issues” information on its websites to reflect
Census 2010 and make it easier to find answers to common-asked
questions. The websites provide information on urban/urbanized
boundaries, new MPOs, designation of MPO and TMA, and the application of
metropolitan planning requirements. Please visit the website(s) at:
http://www.fhwa.dot.gov/planning/census_issues/urbanized_areas_and_mpo_tma
In March 2012, the Census Bureau will be issuing the list of Urbanized
Areas based on the 2010 Census population counts and the new criteria.
The Census Bureau also plans to release TIGER/Line shape files at the
same (or very close) time with these boundaries. Shortly thereafter,
FHWA and FTA will prepare the Federal Register with the listing of new
TMAs.

In all of the excitement over the annual TRB conference, I think we
forgot to mention that the January issue is available.
http://www.fhwa.dot.gov/planning/census_issues/ctpp/status_report/
It includes articles from 2 of the presentations at the TRB Conference
on Census Issues held in October, 2011. We hope the conference summary
report will be available soon from TRB!
