A few of us have been getting calls and emails from people who have been looking at the commuter follow data the Census Bureau just released, the On the Map (LEHD) and some of the earlier flow data. If you have, you probably noticed some interesting (or maybe wierd) things. Needless to say a good understanding of the data is needed to sort out some of the issues. Below are some references and points that may be of interest. What are people noticing with the data? --------------- In the January 20011 Status Report newsletter there is an article from the NY State DOT by the late Nathan Erlbaum which discusses the issues surrounding the various flow data sets. The article “Commutation Flow: CTPP 2000, ACS and CTPP, and LEHD-OTM” can be found at http://www.trbcensus.com/newsltr/sr0111.pdf (starting on page 6). In it is a link to a larger body of work that Nathan did on the topic. a read of this is must if you are having questions about the data. Regarding the LEHD and CTPP flow data, there is an NCHRP report that has been completed that is also worth reviewing. It gets into detail about some of the differences between the two data sets. It can be found at http://onlinepubs.trb.org/onlinepubs/nchrp/docs/NCHRP08-36%2898%29_FR.pdf Elaine Murakami reminds me that 1. LEHD does not include self-employed (approx. 10%) 2. LEHD only recently included federal workers, but does not include MILITARY 3. LEHD is jobs and ACS is "workers at work". Periodically issue like this pop up and there is a discussion on the list serve. there is an archive but off course it takes some time to mine and search through. If anyone is interested in looking through it, it is open to the public and available at http://www.chrispy.net/pipermail/ctpp-news/. There was a discussion around august of 2010 dealing with flow data but it centered more on availability. Hope this helps. -- Ed Christopher 708-283-3534 (V) 708-574-8131 (cell) FHWA RC-TST-PLN 4749 Lincoln Mall Drive, Suite 600 Matteson, IL 60443

[CTPP] New ACS data set

by Patricia Becker

I have spent a bunch of time downloading these new tables and extracting the Michigan sections of each. Imagine my surprise to find that in tables labeled County-MCD, there *are no MCD data for Michigan!! *I guess there are MCD data only for the New England states. I need Detroit!! I surmise that the reason for this is that the only purpose of this data set is to redefine MSAs; in fact, that's why it's on the Metropolitan section of the census web site. When do I get flows for Detroit and the counties of the Detroit MSA? Patty Becker -- Patricia C.

[CTPP] Several New Census Products

by Ed Christopher

Just in case you missed it. Yesterday the Census Bureau put out several journey to work data products. (Accept my apologies for cross-posting) --------------- U.S. Census Bureau Releases American Community Survey (ACS) 2006-10 County-to-County Commuting Flows Products We are pleased to announce the release of the ACS 2006-10 County-to-County Commuting Flow estimates. Though regularly produced commuting data products address where people work and where people live, these flow products uniquely describe the residence to workplace relationship. The ACS 2006-10 County-to-County commuting flows datasets can be found on our Metropolitan and Micropolitan Statistical Areas page (http://www.census.gov/population/metro/data/other.html). An accompanying analysis paper, County-to-County Commuting Flows: 2006-10, is available on our Commuting (Journey to Work) page. 2011 and a working paper and poster that explore Mega Commuting in the U.S.(http://www.census.gov/hhes/commuting/) The ACS provides reliable statistics that are indispensable to anyone who has to make informed decisions about the future. These statistics are required by all levels of government to manage or evaluate a wide range of programs, but are also useful for research, education, journalism, business and advocacy. If you have questions about this survey, please call our Customer Services Center on 1 (800) 923-8282. Thank you, American Community Survey Office U.S. Census Bureau ---------------- Ed Christopher 708-283-3534 (V) 708-574-8131 (cell) FHWA RC-TST-PLN 4749 Lincoln Mall Drive, Suite 600 Matteson, IL 60443
