[CTPP] New report on American Community Survey 2007 data, for San Francisco Bay Area

by Chuck Purvis

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.

[CTPP] ACS Reference Materials

by Ed Christopher

The Census Bureau just released the first of a series of "handbooks" aimed at helping data users negotiate their way through ACS data. This first handbook, "What General Data Users Need to Know" will help general audiences understand the basics of the ACS, its opportunities and challenges, and how to access and use the ACS data on the Census Bureau's Web site. The handbook can be found at http://www.census.gov/acs/www/Downloads/ACSGeneralHandbook.pdf The handbook itself is part of a much broader suite of e-learning ACS materials that can found at http://www.census.gov/acs/www/UseData/Compass/compass_series.html In addition, NCHRP Report 588 "A Guidebook for Using the American Community Survey Data for Transportation Planning" is a MUST HAVE for the transportation planner. It can be found on-line at http://onlinepubs.trb.org/onlinepubs/nchrp/nchrp_rpt_588.pdf -- Ed Christopher Resource Center Planning Team Federal Highway Administration 19900 Governors Drive Olympia Fields, Illinois 60461 708-283-3534 (V) 708-574-8131 (cell) 708-283-3501 (F)

Re: [CTPP] Census Bureau Participant Statistical Areas Program (PSAP)

by Patty Becker

Just to add a bit more information... In addition to tracts and block groups, PSAP includes Census Designated Places and Census County Divisions (the latter used only in about 20 states). MPO-type folks should really be in the middle of this activity, as it is historically organized by metro area with the SDCs working on the non-metro areas. I am what used to be called the "key person" and is now called the "principal contact" for the Detroit area. I've been doing this stuff since before the 1980 census.

[CTPP] Census Bureau Participant Statistical Areas Program (PSAP)

by Murakami

I got a question about PSAP today and thought it would be worthwhile to post to the CTPP listserv: To be short and sweet, PSAP is largely for TRACT and BLOCK GROUP definition for the 2010 Census. http://www.census.gov/geo/www/psap2010/psap2010_main.html There are probably other geographic areas that are also included. >From glancing through the PSAP materials, it appears that the Census Bureau wants you to contact their regional office: http://www.census.gov/field/www/ However, you may want to contact your State Data Center (SDC) who may already have established lead agencies for different counties in your state. http://www.census.gov/sdc/www/ Elaine

[CTPP] RE: seeking guidance on worker flows from the local employment dynamics

by Graham

John, I got involved with this 6 years ago, when Minnesota was the first pilot state. Maybe I can do plain English... Census LED works with state employment agencies (Unemployment Insurance, Labor Statistics, etc.) and with Federal data sources to data-mine residential location and worksite of all covered SSNs. State employment agencies know where everyone works (* everyone who's legally employed, that is). And the Feds know where everyone lives, with linked SSN (again, caveats to this). This project is the fruit of the CIPSEA Act of 2002 - allows agents of the Dept of Labor, Census Bureau, other Fed agencies, to share what would otherwise be "private" or "nonpublic" data. And the deliverable is a Census Block-level origin-destination table with a count of commuting workers (jobs). Very detailed! In fact, so detailed that Census disclosure gurus determined need to limit the detail provided in certain data elements - and to smudge or "fuzz" geographic specificity of employment worksites. I understand discomfort with smudging, fuzzing, and simulating. Still, I'd look to this source for origin-destination pair granularity that future ACS-based CTPP will be flat-out unable to provide. In the future, I can imagine Census LED being combined (thru Iterative Proportional Fitting) with Census ACS summaries (control totals) and ACS PUMS to produce synthetic population with detailed residence-to-worksite linkage. But this is just a dream right now, and not sure it's a vision that others share. -- Todd Graham Metropolitan Council Research 651/602-1322 ---------------------------------------------------------------------- Date: Mon, 6 Oct 2008 08:38:49 -0400 From: "John Hodges-Copple" <johnhc(a)tjcog.org> Subject: [CTPP] seeking guidance on worker flows from the local employment dynamics On The Map data To: <ctpp-news(a)chrispy.net> Does anyone have a short, "plain English" explanation of the residence-to-workplace flows from this data and how it compares to the old long-form commuting data from the 2000 and earlier censuses (censi?). I read "synthesized" data and little red flags go up. Specifically, is this data based on actual residence and workplace data of real individuals (as with the Census), or are the residence and workplace locations from different data sources and the travel between the 2 synthesized in some way, as a travel demand model would create travel patterns between the 2? Any guidance would be appreciated; my brief hunting through the documentation didn't give me the clear specifics I was hoping.
