Census "Planning DataBase" -- predicting response and targeting to increase response

by Elaine.Murakami＠dot.gov

Target audience for this post: survey methodologists On Nov 19, I attended an ACS Data Users Group webinar hosted by the Population Reference Bureau and Sabre Systems. The topic was the Planning Database (PDB), which is a database at the tract and block group level, focusing on low response. The main objective is to figure out where the Census will have lower response with the 2020 Census and plan to implement different techniques to improve response rates in those areas. www.census.gov/research/data/planning_database<http://www.census.gov/research/data/planning_database> The speakers were Nancy Bates and Travis Pape. The PDB includes the geography (tract and block group), demographic characteristics, and then, Census operations data, e.g. mail-back, bilingual rates, the 2010 Census Mail return rate AND the LOW RESPONSE SCORE, based on a model using 5-years of ACS data. The model includes 25 variables, of which the top 3 variables were: rent (vs own); age ( 18-24), and female head of household with no husband present. Other variables include household size, presence and age of children, poverty, education, race and Hispanic origin. The regression results are R2 of .56 at the block group level, and R2 of .55 at the tract level. These results are for mail-back returns, and the Census Bureau is planning on over 60% returns for the 2020 Census using Internet, so the results may be different after newer ACS results which included Internet response method are incorporated into the model. Currently, the 2014 PDB which includes 2008-2012 ACS estimates and 2010 Census operations data is available, and an updated PDB based on more recent ACS will be available approximately in March 2015. The files are only available as nationwide files, zipped CSV format, one file for tracts and one file for block groups. The tract level file is 86 Mb. The Block Group file is 152 Mb. Bottom line - the model variables seem consistent with the results of non-response to household travel surveys, so I am thinking that when a large household travel survey is being planned, these data could also be useful for targeting different approaches to improve response rates, or oversampling housing unit addresses in low responding areas. Hope I didn't make any grievous errors in my summary above! If I did, I hope that someone from the Census Bureau will post corrections.

Call for Abstracts: 2nd Annual ACS Data Users Conference May 2015

by Elaine.Murakami＠dot.gov

Abstracts are due January 14, 2015. This conference will be held one week before the TRB Planning Applications conference, so I know this is likely to cause low interest in this. Nonetheless, I hope that some transportation and especially CTPP data users will be able to participate in this conference. Several MPOs participated last time and we had a nice lunch together. It is highly unlikely that I can attend because of travel budget limitations. I encourage you to consider submitting an abstract. It is always good to document the transportation applications of ACS to a non-transportation audience, and to get the attention of Census Bureau staff, even if they might have to participate via web!

Deadline: Jan. 14, 2015 Acceptance Notification Date: Feb. 20, 2015 The second annual American Community Survey (ACS) Data Users Conference will bring together ACS data users and staff from the U.S. Census Bureau to increase understanding of the value and utility of ACS data and to promote information sharing among data users about key ACS data issues and applications. The conference will include contributed presentations by ACS data users, invited sessions, hands-on training, and opportunities for networking. We are inviting abstracts on any topic relating to ACS data issues and applications, but we are especially interested in new and innovative uses of ACS data, and ACS applications that inform policy and business decisions.

History of CTPP

by Elaine.Murakami＠dot.gov

I was recently asked about 1970 and 1980 journey-to-work data at the tract level, so I thought I would share some historic materials. Bottom line, around 1998 and 1999, we attempted to collect 1980 UTPP files, but were able to find only about 20 files, which are stored at Cambridge Systematics and available via ftp. For more information, please contact ctppsupport(a)camsys.com<mailto:ctppsupport@camsys.com> The CTPP program was not nationwide until the 1990 Census long form tabulation. In 2010, Ed Christopher and I wrote a chapter for the Encyclopedia of the U.S. Census about Transportation Uses of Census Data, which include a very brief summary of the CTPP. This book is a reference document, I think, mostly found at libraries. Margo J. Anderson, Constance F. Citro, & Joseph J. Salvo (Eds.). (2012). Encyclopedia of the U.S. census. (2nd ed.). Washington, DC: CQ Press. doi: http://dx.doi.org/10.4135/9781452225272 I have attached a couple of alternate sources: 1. A 2008 ppt from Ed Christopher, as a PDF file. Perhaps we can ask Ed to update his slides with information about the 2006-2010 CTPP, and the AASHTO CTPP Oversight Board. 2. A few scanned pages from the 1994 TRB Conference on "Decennial Census Data for Transportation Planning", written by Phil Fulton, who was at the Census Bureau Journey to Work branch. One interesting sentence to me was about updating GBF/DIME files in the 1980s, the predecessor to the TIGER files. The 1980 UTPP were delivered to transportation agencies on 9-track tapes.

NEXT County-to-County Journey to Work Flow table

by Elaine.Murakami＠dot.gov

Some of you have asked when the next journey to work tabulation would be available, and I have answered that the AASHTO CTPP program is not planning on another flow tabulation until the 2012-2016 ACS data are accumulated for a 5-year data product. However, the Census Bureau, independently of the CTPP program, will be producing a county-to-county commuting flow file for 2009-2013 5-yr ACS. It will include total flows, AND a short list of travel mode (4 categories....drove alone, carpooled, transit, other). It is expected to available approximately May 2015. Hurrah! We seem to making progress in having the Census Bureau increase relevant transportation tables as part of their standard products, reducing what is needed from a special tabulation which costs money!

Contact information for CTPP Tech Support

by Elaine.Murakami＠dot.gov

Hi Everyone - The CTPP program has had great continuity in technical support staff for many years, with Nanda Srinivasan (now at the DOE Energy Information Administration), and more recently, Liang Long, now working with "big data" for marketing purposes. We now have a new person, Ms. JJ Zang at Cambridge Systematics. JJ has dual master's degrees from UC Irvine, in Transportation System Engineering, and Urban and Regional Planning. She will have other people at Cambridge Systematics helping her in her initial months with the program. If you need help with the CTPP data access software, or the software for older versions of CTPP, please contact CTPPSupport(a)camsys.com<mailto:CTPPSupport@camsys.com>. If you are interested in on-site training, please contact Penelope Weinberger at AASHTO CTPP program: pweinberger(a)aashto.org<mailto:pweinberger@aashto.org> Elaine Murakami FHWA Office of Planning 206-220-4460 (in Seattle)
