[CTPP] GET READY FOR DECEMBER 9: ACS 2005-2007 Data Release

In preparation for the release on December 9, FHWA have hosted 2 web training sessions (Dec 2 and 5) on accessing the ACS data. The materials were the same on both dates. If you were unable to attend, the session on Dec 2 was recorded, and is available: http://fhwa.na3.acrobat.com/p97212507/ The Census Bureau has released a list of the geographic areas for which data will be released on December 9. http://www.census.gov/acs/www/Products/users_guide/2005_2007/index.htm As a quick reminder, the population threshold for releasing tabulations from the 3-year ACS is 20,000. Approximately 60 percent of counties are included. This data release does NOT include census tracts or other "small area" data. The geographic units with complete coverage are limited to States and PUMAs. That is, tabulations for counties and places are like "swiss cheese." Even if a county has (for example) a population of 100,000, some of the cities in that county may have more than 20,000, and others fall under 20,000 population. Tables for the county will be issued, but only the cities over the 20,000 threshold will have data published. The Census Bureau has shapefiles available: http://www.census.gov/geo/www/tiger/tgrshp2007/tgrshp2007.html Good luck! And don't forget to share your results with the CTPP listserv!
