includes links to BOTH
the 2005 profiles and the 2000 profiles.
Nathan Erlbaum from New York State DOT pointed out a problem with the
file names. Thank you Nathan for your sharp eyes. All three profiles
for 2005 have the SAME filename (on the server, they are in separate
directories). However, if YOU are downloading them, you should SAVE
them as DIFFERENT NAMES, otherwise, they will overwrite each other!
For example, the Place of Work profile for Alaska is Alaska.xls, AND
the Place of Residence Profile is also named Alaska.xls.
I have asked the AASHTO web staff if they can change the filenames, but
it will take them a while before they can rename all the files and
repost to the web.
Thanks for your patience.

Subject: [CTPP] MORE Transportation Profiles using the 2005 ACS
The AASHTO webpage on CTPP Profiles has been updated.
There are 3 different sets, the second and third sets are the "new"
ones, and are based on the October 2006 release of 2005 ACS data. The
same cautions about interpreting the results from ACS, compared to
decennial Census remain the same.
-The first set is by Place of Residence. (We posted these several months
ago). Probably, we will need to go back and add more geography to this
-The second set is also by Place of Residence and tabulates WORKERS and
HOUSEHOLDS by household characteristics such as HOUSEHOLD SIZE and
-The third set is by Place of Work. We do not have "metropolitan areas"
here, since the results are going to be nearly the same as for Place of
Residence. However, we included "State" totals, even if they are also
going to look very similar to Place of Residence tabulations (except
Washington, D.C.) These are "DRAFT" and we plan to add more
information about Margins of Error (in NUMBERS), where it currently is
limited to MOE in percent.
These profiles will be posted as FHWA 508-compliant HTML in the near
future. I haven't found the time to finish a "highlights" document
similar to the one I did for the first set of profiles.
Also, we have added several links to our ACS page, including links to
web-based training. A good starting point for learning about using
American FactFinder to access ACS data, please see the Ken Bryson
Nanda Srinivasan (now on vacation until March 2) did the hard work in
producing these profile sheets.
