Hello CTPPers:
The detailed 2007 American Community Survey data for journey-to-work
and household characteristics was released by the Census Bureau on
September 23, 2008. We completed our first report on the ACS 2007 for
our region, on October 2nd. The 30 page report is here:
http://www.mtc.ca.gov/maps_and_data/datamart/census/
The most interesting finding is a statistically significant (95% CL)
increase in transit commuting, 2006 to 2007, from 315,000 to 336,000.
The increase in our regional share of transit commuters (9.5 to 10.0
percent), was not a statistically significant increase (95% CL) (though
it was significant at a 90% CL).
Commute times are stable, at about 27 minutes per one-way commute.
Intra-county commute shares (% living and working in same county) has
remained stable between 2000 and 2007, at about 72 percent intra-county
commute.
We also produce tables on housing affordability, poverty, race, and
household vehicle availability, since those are topics of interest to us
and our policy board.

I hope that everyone is enjoying looking at the new data from ACS. Most of the articles I've glanced at today have been about the diversity of people in suburbs, and the growth in non-English speaking populations. Since I have received several additional queries about the materials from last week's web training, here is one more email:
FHWA hosted 2 web training sessions (Dec 2 and 5) on accessing the ACS data. The materials were the same on both dates. If you were unable to attend, the session on Dec 2 was recorded, and is available:
http://fhwa.na3.acrobat.com/p97212507/
If you are interested in the powerpoint presentations, you can go into the meeting room http://fhwa.na3.acrobat.com/ctpp1 as a GUEST, and download the files.
The Census Bureau has shapefiles available:
http://www.census.gov/geo/www/tiger/tgrshp2007/tgrshp2007.html
Also, IPUMS has PUMA boundaries that are more detailed than the Census Bureau version.

Subject: [CTPP] Thanks for Putting Training and Power Point On-Line
Thank you very much for putting the audio of the training session held December 2nd and the accompanying power point on-line. This will be a big help.

I will be out of the office starting 12/05/2008 and will not return until
01/08/2009.
I am currently on vacation and will be back in the office on January 8th,
2009. Please contact Dan Goldfarb (dgoldfarb(a)camsys.com) with any project
related questions.
In preparation for the release on December 9, FHWA have hosted 2 web
training sessions (Dec 2 and 5) on accessing the ACS data. The materials
were the same on both dates. If you were unable to attend, the session
on Dec 2 was recorded, and is available:
http://fhwa.na3.acrobat.com/p97212507/
The Census Bureau has released a list of the geographic areas for which
data will be released on December 9.
http://www.census.gov/acs/www/Products/users_guide/2005_2007/index.htm
As a quick reminder, the population threshold for releasing tabulations
from the 3-year ACS is 20,000. Approximately 60 percent of counties are
included. This data release does NOT include census tracts or other
"small area" data. The geographic units with complete coverage are
limited to States and PUMAs. That is, tabulations for counties and
places are like "swiss cheese." Even if a county has (for example) a
population of 100,000, some of the cities in that county may have more
than 20,000, and others fall under 20,000 population. Tables for the
county will be issued, but only the cities over the 20,000 threshold
will have data published.
The Census Bureau has shapefiles available:
http://www.census.gov/geo/www/tiger/tgrshp2007/tgrshp2007.html
Good luck! And don't forget to share your results with the CTPP
listserv!
