[CTPP] ACS Commuting Data

I received this in my email but thought answering it would be relevant to the larger CTPP group. ----------- Garth wrote: Elaine/Ed: Has there been any county-to-county commuting data yet from the American Community Survey? Unless I've missed it somewhere, I don't think there has been since not all counties are available yet. Will county-to-county commuting flow data be available in the next ACS/CTPP multi-year product? If so, are we still looking at 2011 for the release of such data? I'd appreciate any clarifications/references you could provide. Thanks, Garth ----------- The short answer is that there has not been any county-to-county commuting data yet and the Census Bureau has been mute on the question of ever producing any as part of their standard tabulation program. Using "Magic 8 ball" speak one could speculate that "it is doubtful" if they ever would. However, all is not lost! The transportation community has been very vocal that "We NEED Flows." As such the AASHTO CTPP Oversight Board is positioning itself to request a set of tables which will include flows. The request is set to get to the Census Bureau by April 1, 2009. Currently, a task force is working on the tables and ironing out a few bumps in terms of what tables to ask for and the modal collapsing schema that might pass disclosure rules. The task forces is very close to done. (The December newsletter talks about the disclosure hurdles http://www.trbcensus.com/newsltr/sr1208.pdf). Once we get the tables pinned down in the next few weeks we will certainly be circulating them to our large community. In terms of tables, the request will go to the Census Bureau by April 1st and then the Disclosure Review Board will have to rule and then cost estimates will need to firmed up and contracts written. If all goes well, the tables would use the 2006, 2007 and 2008 ACS data with possible receipt of some data by 2010/2011. We have been told that the actual production of the tables can go quite quickly once we get over all the stuff at the front end. Right now, a lot has to fall in place but the message has been heard that, FLOW DATA is MUST. Right now the only reference is the letter that was sent from the Oversight Board on February 9th stating that we are working on a 3-year ACS data table request. I have attached it. Stay tuned.....
