Hi John, and everyone else- 1. If you need a SHORT extension to submitting your TAZ and TAD boundaries, please contact the Census Bureau Geography Staff IMMEDIATELY. 301-763-1099 email: geo.taz.list(a)census.gov 2. What if your TADs have less than 20,000 residential population? The goal is to define a geographic unit that will pass the Census Bureau's 3-year tabulation geography threshold (20,000 population). This way, after the 2006-2010 (5 year) CTPP is delivered to AASHTO, there is a potential to request another 3-year CTPP tabulation sometime in the future using TAD. Right now, the geographic unit in the 3-year CTPP is limited to PUMA, County and Place with 20,000 population or more. This is not very useful for large cities.

Sharp - ACOG Sent: Tuesday, June 28, 2011 10:37 AM To: ctpp-news(a)chrispy.net Subject: [CTPP] RE: TAZ delineation update Being a little slow on the TAZs. However, a question on the TADs. What do we lose (data wise) if we have some TADs that total only 15,000, rather than the 20,000? Thanks, John From: ctpp-news-bounces(a)chrispy.net [mailto:ctpp-news-bounces(a)chrispy.net] On Behalf Of Elaine.Murakami(a)dot.gov Sent: Thursday, June 16, 2011 2:49 PM To: ctpp-news(a)chrispy.net Subject: [CTPP] TAZ delineation update Over 100 agencies have ALREADY submitted their files to the Census Bureau Geography Division, with at least 10 agencies submitting files today (June 16). The CB GEO staff have found that the TAZ files look pretty good, and although there are some TAZs that look "too small" these are often in areas with parks or water areas. They also said that the TADs look VERY good, with very good adherence to the 20,000 population threshold. Thank you to everyone! I know the rest of you who are participating in the program are working very hard to complete this task. Getting the TAZ and TAD into Census TIGER is one step for the CTPP 5-year tabulation. This tabulation will use ACS records from 2006-2010. AASHTO is expected to submit the 5-year table list to the Census Bureau's Disclosure Review Board this July.

[CTPP] Historic county-to-county flows

by Elaine.Murakami＠dot.gov

The CTPP group LOVES it when someone asks an interesting question. Today's interesting question is: Where can I get 1980 county-to-county flow data? The answer is: http://www.bea.gov/regional/reis/jtw/ The 1980 UTPP was NOT a nationwide package, but individual MPOs and state DOTs contracted with the Census Bureau. Fortunately, BEA had a special tabulation nationwide for these flows. These are based on the 1980 Census "long form" sample. Elaine Murakami FHWA Office of Planning 206-220-4460

[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.

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

[CTPP] Group quarters raw data

by Mara Kaminowitz

Does anyone know if there is a Microsoft Access import specification for the group quarters data located at http://www2.census.gov/census_2010/02-Advance_Group_Quarters/? The geo file is the same but the data table layout is different. Mara Mara Kaminowitz GIS Analyst .........................................................................
