[CTPP] more on 2010 Census Summary File 1

by Elaine.Murakami＠dot.gov

7 States have now been released including California. I only call this out specifically since California includes 12 (?) % of the total U.S. population. http://2010.census.gov/news/press-kits/summary-file-1.html Also, below is an email from Bob Schwartz in PA, which I hope he doesn't mind my sharing with the listserv. His email has been forwarded to Census Bureau staff, but we have not gotten any response yet. In anticipation of the 2010 Census Summary File 1 for Pennsylvania, I downloaded the 2010 Census Summary File 1 for Hawaii and immediately noticed problems with the file and the documentation. 1. I unzipped the zipped file and noted that the 47 data segments have a suffix of ".sf1", which it seems to me, should be ".txt". You can rename each file to a ".txt" but why should that be necessary? 2. In the "README File for 2010 Census Summary File 1 Delivered via FTP", is the statement "This is done so that individual files will not have more than 255 fields..." WRONG! The explanation for this is that there are fewer than 255 data fields HOWEVER, EVERY DATA FILE HAS 5 FIELDS PRECEDING THE ACTUAL DATA. Therefore, if you add 5 to every number under the column "Number of data cells" to get the total number of fields, you will find 9 files with more than 255 fields! These 9 files cannot be imported into Microsoft Access which is my database. 3. In the "README File for 2010 Census Summary File 1 Delivered via FTP", is the statement "All fields classified as numeric (N) should be imported as long integers" WRONG! Tables P13, P17, P37, and H12 (and their racial files A-I) are expressed decimal fields which should not be set to integer.

[CTPP] CTPP 2010 Release Question

by Eatman

Hi All, My MPO asked me when the CTPP 2010 data would be released to benefit future TDM updates. Sometime in 2012? Any specific date/month? I couldn't find any information on the various websites but I may have missed something. Thanks! Mark R.

[CTPP] Summary File 1 from 2010 Census has started to be released

by Elaine.Murakami＠dot.gov

Alabama and Hawaii have been released. Attached is my shortened version of the table list. These tables include many tables of interest, including: average household size to 2 decimals; Household type by Household size; age and sex; and several tables on group quarters populations. Good luck with AFF2! Ed Christopher and Liang Long went to a workshop on using Data Ferrett http://dataferrett.census.gov , and think you might prefer to access the data using Data Ferrett instead of using AFF2. I am trying to schedule a CTPP webinar after more of the Summary File 1 files have been released. Elaine Murakami FHWA Office of Planning 206-220-4460

The forum discussed demographic trends from the recently released 2010 census. As expected demographic shifts will have a profound effect on the demand for transportation in coming years. Panels members also examined the transportation implications for urban and rural populations, disability, migration, race, immigration and more. Speakers and Panelists included: Dr. Robert Groves, U.S. Census Dr. William Frey, Brookings Institution Dr. Mark Hugo Lopez, Pew Hispanic Center Dr. Barbara Altman, National Center for Health Statistics Dr. John Cromartie, U.S. Department of Agriculture Dr. Johanna Zmud, Rand Corporation Dr. Richard Marottoli, Yale University Beth Jarosz, San Diego Association of Governments Michael Alexander, Atlanta Regional Commission ---- Ed Christopher 708-283-3534 (V) 708-574-8131 (cell) FHWA RC-TST-PLN 4749 Lincoln Mall Drive, Suite 600 Matteson, IL 60443

[CTPP] how to unsubscribe to the CTPP listserv

How much growth (residential population and employment) has occurred and WHERE. If there is a lot of growth, you should make new TAZs and not worry about keeping the same geography. 2. How big or small were the TAZs for CTPP 2000? (In a few cases nationwide in 2000, the TAZs were very very small and the results were probably not reliable). We have never controlled the size of TAZs, and even this time, it is a suggested threshold, not a firm threshold. The software allows you to define very small TAZs, but gives you a warning. You probably DON'T want to compare TAZ-to-TAZ flows between 2000 and the 2006-2010. Most likely, I think that people will use the 2006-2010 CTPP TAZ-to-TAZ flows as a validation data source for their travel demand model. And in some cases, will use an adjusted TAZ-to-TAZ flow as inputs into HB-Work trips (after accounting for the fact that this represents only the journey-TO-work). For comparing between the 2 timeframes, one which is point-in-time and the other a "period estimate", given the ACS sample size, you would be better off to make SuperTAZs (combinations of TAZs) to do the comparison. The UNWEIGHTED sample size after five years of ACS data collection (2006-2010) is about one-half the sample size from the Census 2000 long form, therefore the margin of error is much higher. We are asking MPOs (and State DOTs) to also define TADs, which is another word for a Super TAZs, using a minimum of 20,000 population. This would be approximately the size of 4 or 5 census tracts. For your comparison task, you might want SuperTAZs that are smaller than that. Glad to hear that you understand the difference between your model TAZs and the Census-TAZs defined for CTPP. Elaine Murakami FHWA Office of Planning 206-220-4460 From: ctpp-news-bounces(a)chrispy.net [mailto:ctpp-news-bounces(a)chrispy.net] On Behalf Of Kendra Watkins Sent: Wednesday, May 25, 2011 7:29 AM To: ctpp-news(a)chrispy.net Subject: [CTPP] taz delineation Could someone shed some light on how reliable TAZ to TAZ flow comparisons will be between the 2000 CTPP data and the 2006 - 2010 release? I am asking because as I delineate TAZ's I am trying to prioritize my "rules" for delineation and wonder if TAZ continuity will really be useful if the data won't be comparable anyway. Of course we are keeping our smaller travel model zones as consistent as possible, but our Census TAZ's will be in many cases quite a bit larger.
