Like Ms. Bousefield in Chicago, I find the HUD vacancy figures running very low. The ACS county-level vacancy data appear far more accurate in our area, but they are not available at the tract level yet. However, the HUD data do appear to reflect different characteristics of tracts - they correctly identify areas of generally higher vacancy. Therefore, I may be able to use the HUD figures to identify changes in vacancy by tract over time. The HUD figures do not separate businesses from residences. Therefore, like so many other sources, they are useful but not fully compatible with other data sets. Jonathan Lupton Metroplan - Little Rock AR

TAZs, TAZs Everywhere

by ed christopher

The Florida DOT has just posted a 70 page report discussing TAZs and their construction. While the information is for the model users community in Florida there is a wealth of information in the report that those who think about such things will find of interest. The document is well worth adding to any list of TAZs references that you may have. The report can be found on the Florida Transportation Modeling web site at http://www.fsutmsonline.net/index.php?/site/directory/model_docs The direct link to the report is http://www.fsutmsonline.net/images/uploads/reports/FDOT_TAZ_White_Paper.pdf If other States or Regions have similar documents I wouldn't mind learning about them and adding them to our ever growing list of data related resources. -- Ed Christopher FHWA Resource Center 19900 Governors Drive Olympia Fields, Illinois 60461 708-283-3534 (v) 708-283-3501 (f) 708-574-8131 (cell)

Impact of Congressional Continuing Resolution on Census programs

by Murakami, Elaine

FYI, via the Association of Public Data Users. _____ From: Patty Becker [mailto:pbecker@umich.edu] Sent: Tuesday, September 25, 2007 8:36 AM To: APDUMEM(a)apdu.org Subject: [APDU members] Impact of Congressional Continuing Resolution Hi all, At this point, it is clear that the Congress will not complete its budgeting job this week in time for the new fiscal year, making a continuing resolution (CR) inevitable. Below, please find a communication from Terri Ann Lowenthal, APDU Board member, about the impact of the CR on the Census Bureau: Good afternoon, census stakeholders. A quick update on the status of Fiscal Year 2008 funding for the Census Bureau, and a call for IMMEDIATE help in convincing House and Senate appropriators to provide adquate funds for Census in the short-term Continuing Resolution before Congress this week. As you know, the fiscal year ends this weekend. The House will take up a CR as soon as Wednesday. The CR would allocate funds at the FISCAL YEAR 2007 LEVEL through November 16 (at the earliest; another CR might be necessary then). This outcome would spell disaster for key Census programs. The Census Bureau received $893 million in FY07. For FY08, the Administration requested $202.8 million for Salaries & Expenses, and $1,027.4 million for Periodic Censuses and Programs. The House bill provides $196.8 million for S&E and $1,025.4 million for Periodics. The Senate committee bill provides $226.2 million for S&E and $1,020.4 million for Periodics. Overall, the Administration requested a 37.7 percent increase for the Census Bureau, in recognition of final preparations for Census 2010 and the 2007 Economic Census and Census of Governments, among other important activities. Unofficial word from known sources (no one in the Census Bureau is allowed to speak about this publicly) is that proposed funding levels in the CR would endanger conduct of the 2008 Dress Rehearsal (preparations are in full swing and the DR takes place on a census schedule next March - summer) or use of handheld computers for non-response follow-up in the census. The handhelds are being developed for deployment in the Dress Rehearsal. If they are not used then, it is very possible/likely they will not be used in 2010. Please make any immediate contacts you can with staff/Members on House and Senate Appropriations Committees, or other influential Members of Congress, in support of an exception to proposed funding levels for the Census Bureau in the CR. The Census Bureau is on a major cyclical funding upswing ... it cannot continue to function at last year's funding levels for a few months. Keep in mind that the 2007 Economic Census and Census of Governments are starting this fall, with forms going out in December/January. That cannot be delayed either. Please also share this message with others in your census network. =============================== Patricia C.

2006 ACS data release from the Census Bureau DECODER RING

by Murakami, Elaine

Here is the REAL message I meant to send! Apologies for hitting the "send" button earlier. Thank you to Celia Boertlein and Kin Koerber at the Census Bureau for the original materials and the recent updates related to 2006 ACS tabulations. September 27 is the scheduled release date for the remainder of 2006 ACS data standard products. Also, comments to the Federal Register Notice on ACS Data Products (Docket 070725407-7408-01) http://a257.g.akamaitech.net/7/257/2422/01jan20071800/edocket.access.gpo .gov/2007/E7-16850.htm are due September 28. ACS TABLE NAMING AND NUMBERING The first character in the table is a key to the type of the table. Subject "S" Several tables compiled together addressing a specific subject. Limited to areas with 1+ million population. Base or Detailed "B" These tables are used to create the Subject tables, but can be used independently. Collapsed "C" These tables are a smaller version of the Base tables with a reduced number of categories to reduce suppression. However, some tables may still be suppressed if the coefficient of variation among the cells is too high. Ranking "R" These tables sort the results based on individual values, for example, average travel time, or percent using transit as means of transportation to work. For 2005, these are given for State totals. Data Profiles: There are 4 profile sheets: demographics, social, economic, housing, and 1 narrative document. The economic profile includes workers and commuting. Selected Population Profiles: These are tables by race, ethnicity and ancestry. All the JTW and Place of Work tables begin with "08". As for the detailed (base) tables, there is somewhat of a pattern. Those beginning with B080 or C080 support the Subject Table S0801. Also included in that set are the Place of Work by metro/micro/non-metro or -micro tables (B08016-B08018/C08016-C08018). The latter are included with the others since S0801 uses the other Place of Work tables. However, S0801 does use some JTW tables. The workplace-based tables that parallel those detailed tables start with B084 or C084. The last two digits are the same for corresponding residence-based and workplace-based tables. The detailed tables that are used for the Means of Transportation Subject Table (S0802), are numbered starting with either B081 or C081. The workplace-based tables that parallel those detailed tables start with B085 or C085. The last two digits are the same for corresponding residence-based and workplace-based tables. The household data detailed tables that were requested by DOT and not used in any other products are numbered starting with either B082 or C082. These are: B08201: Household Size by Vehicles Available B08202: Household Size by Number of Workers B08203: Number of Workers by Vehicles Available For the 2006 ACS, new one-dimensional JTW detailed tables have been added, and start with either B083 or C083. The workplace-based tables that parallel those detailed tables will start with B086 or C086. The last two digits will be the same for corresponding residence-based and workplace-based tables. B08301 Means of Transportation to Work B08302 Time Leaving Home B08303 Travel Time There will be holes in the numbering where tables are removed. The links to the topic search results: The link for Journey to Work is - http://www.census.gov/acs/www/acs-php/2006_experienced_users_guide.php?a cs_topic=Journey+to+Work for Place of Work -- http://www.census.gov/acs/www/acs-php/2006_experienced_users_guide.php?a cs_topic=Place+of+Work for Vehicles Available -- http://www.census.gov/acs/www/acs-php/2006_experienced_users_guide.php?a cs_topic=Vehicles+Available Another resource is the ACS 2006 Data Users Handbook -- http://www.census.gov/acs/www/Downloads/Handbook2006.pdf The CB's Journey to Work and Migration branch was asked to reduce the number of ACS standard tables for 2006 and beyond. Here's the list of what was removed. 1) Subject Table S0803. Worker characteristics crossed by sex. These subject tables are only produced for areas with 1 million+ population. 2) Mean travel time in S0802. Delete the mean travel time to work column from subject table S0802. Some tables with travel time distributions remain e.g. B08012, B08134. 3) Means of Transportation by Marital Status : This change deletes all the marital status by means of transportation data. 4) Means of Transportation by Educational Attainment: This removes all the educational attainment by means of transportation data. 5) Means of Transportation by Household Type: This removes all the household type by means of transportation data. Don't forget that we created our own profiles using the 2005 ACS results. These are available at: http://ctpp.transportation.org/home/default.htm and include some data from 1990 and 2000. We do not plan to prepare new profiles using the 2006 ACS results, as the differences are likely to be small except for areas with large group quarters population, and due to limitations in staff resources.

2006 ACS data release by Census Bureau

by Murakami, Elaine

The deletions you mention were all deleted and the tables mentioned that were to be added were. The links to the topic search results STILL link to 2005 Data Users Guide (I have no idea why but suspect that they've not finished up the 2006?) but yours no longer work -- The link for Journey to Work is now -- http://www.census.gov/acs/www/acs-php/experienced_users_guide.php?acs_to pic=Journey+to+Work for Place of Work -- http://www.census.gov/acs/www/acs-php/experienced_users_guide.php?acs_to pic=Place+of+Work for Vehicles Available -- http://www.census.gov/acs/www/acs-php/experienced_users_guide.php?acs_to pic=Vehicles+Available You may also want to link to the 2006 Data Users Handbook -- http://www.census.gov/acs/www/Downloads/Handbook2006.pdf I rather think that it could be useful as general overview although there may be other things off the "How to use the data" page that might also be mentioned -- http://www.census.gov/acs/www/UseData/index.htm http://www.chrispy.net/pipermail/ctpp-news/2007-March/001569.html I will ADD to the email to list the specific ADDED tables in B083, C083, B086 and C086 series.

Useful links to training on using ACS data

by Murakami, Elaine

Now that the Census Bureau is busy releasing the 2006 ACS data, I thought it would be timely to post a few links on using the ACS data. It is VERY IMPORTANT to understand that the biggest difference between the 2006 and 2005 ACS is that GROUP QUARTERS population was ADDED in the 2006 sample. Areas with large Group Quarters population will see the greatest differences between 2006 and 2005 results. Workers who live in Group Quarters are more likely to walk to work, so you may see shifts in distributions of means of transportation to work in these areas. The population threshold for reporting 1-year ACS data is still 65,000 persons, based on place of residence. The 2005 and 2006 ACS standard tabulation include tabulations for PLACE OF WORK called "for workplace geography". Also, the "key" to finding tables on "journey to work" is "08", for example: B08###, or C08###, or S08##. Cynthia Taeuber's book, "American Community Survey data in Community Planning" (Trafford Publishing, 2006 website: trafford.com/06-2809 ) is an easy-to-understand document that covers basic information about ACS, but most importantly, understanding sampling error and confidence intervals. Note: The Census Bureau is now using the term "Margin of Error" to reflect sampling error instead of using confidence intervals (the estimate with an upper and lower bound). You can order it directly from Trafford.com, which is a "print on demand" publishing house, but I just found it on Amazon. (priced at $26.37 and listed as "in stock" ) Also, Cynthia's material completed for Brookings Institute "for journalists" is on-line at: http://www.brookings.edu/metro/umi/events/20061115_ACSreferenceguide.pdf This document on the Census Bureau's webpage discussing the 2005 ACS is also useful. http://www.census.gov/acs/www/UseData/advance_copy_user_guide.pdf The FHWA page also includes some material on using ACS data, which was developed for earlier releases of ACS, but are still relevant. http://www.fhwa.dot.gov/planning/census/acs.htm Because we prepared profiles sheets from the 2005 ACS data, with comparison to Census 2000, we are currently NOT planning to issue NEW profiles using the 2006 data. We are currently focusing on PLANS for the NEXT CTPP, using the first 3 year accumulation of ACS data (2005, 2006, and 2007), and conducting research on 1) improving workplace imputation for ungeocoded survey responses, and 2) alternative approaches to disclosure avoidance, to avoid the data suppression problems that arose in the CTPP2000. If you have ideas for the 3-year CTPP product, especially NEW or DIFFERENT Tables, please let me know! Elaine Murakami FHWA Office of Planning 206-220-4460

A big chunck of ACS data in now out on the street

by Ed Christopher

Taken from the Census Bureau Press Release........Don't forget to do your significance tests when comparing to 2005 and 2000 and keep in mind that the 2006 data contains group quarters. The Census Bureau today released 2006 ACS social, economic, and housing characteristics, demographic and housing estimates, and PUMS data. Data are again available for the nation, the 50 states and the District of Columbia, Puerto Rico, every congressional district, and all counties, places, and metropolitan areas with populations of 65,000 or more. Key topics included in this release consist of: *Educational attainment *Industry *Occupation *Class of worker *Journey to work *Employment status *Work status *Veteran status *Housing *Households and families *Marital status *Migration These data may be found at: http://factfinder.census.gov/home/saff/main.html?_lang=en. As noted in the 2006 ACS data release on Aug. 28, 2007, this year marks the first time that ACS data products cover the total U.S. population, including populations residing in group quarters (such as prisons, college dormitories, military barracks, and nursing homes). The Census Bureau's Web site now contains guidance on comparing 2006 ACS data to 2005 ACS data, as well as comparing 2006 ACS data to Census 2000 data. This guidance may be found at: http://www.census.gov/acs/www/UseData/compACS.htm. The final release of 2006 ACS data will occur on Sept. 27, 2007 and consist of selected population profiles/tables for about 200 selected population groups by race, Hispanic origin, and ancestry. In addition, this release will include group quarters profiles, the first such release since the 1990 Census. Also released at that time will be workplace geography tables. -- Ed Christopher 708-283-3534 (V) 708-574-8131 (cell) FHWA RC-TST-PLN 19900 Governors Dr Olympia Fields, IL 60461

American Community Survey Alert, Number 52 (SPECIAL NOTICE)

by Murakami, Elaine

Some of you have already seen this, but I thought it was important to re-post to the CTPP list. The Census Bureau is asking for comments on data products for the ACS multiyear tabulation. The first release will use responses from 2005 thru 2007. The population threshold for 3-year accumulations from ACS is 20,000 persons, so data for many more counties and places will be available, compared to the 1-year ACS tabulations. Responses are due by September 27, 2007.
