Re: [CTPP] American Community Survey 2004 is now available

The revised ACS 2004 profile data for the single-year and multi-year profiles are now available on AFF with the corrected ancestry data. "Chuck Purvis" <CPurvis(a)mtc.ca.g ov> To Sent by: <ctpp-news(a)chrispy.net> ctpp-news-bounces cc @chrispy.net Subject [CTPP] American Community Survey 08/31/2005 04:36 2004 is now available PM TO: CTPP-News The Census Bureau released the 2004 American Community Survey data on Tuesday, August 30th. The Bureau had a kickoff news conference on "Income, Poverty & Health Insurance Coverage" on Tuesday morning. ACS data is available on the American Factfinder, at: http://factfinder.census.gov/ Data from the 2004 ACS is available for most geographic areas of 250,000+ population, including: states, counties, places, congressional districts, CMSAs, PMSAs, MSAs (old metro definitions), county subdivisions (in 3 states). The American Factfinder (AFF) appears to be changing on a day-by-day basis. Yesterday morning we were able to access the 2004 ACS "data profiles" and the "multi-year profiles." After we returned from lunch, they were gone. Hopefully the Bureau is working on it and will restore those "profiles" ASAP. They're extremely important for understanding significance of change from one year to the next. The "profile" series is a group of four data highlight reports: demographic, social, economic and housing. The AFF "Ranking Tables" are apparently the same as previous years' releases. A very nice feature is the ability to click on a row / geographic area of interest, and see which areas are "not significantly different" than the area you selected. This can be very useful when characterizing your community, e.g., the commute time of San Jose resident workers is very similar to the commute times for residents of Atlanta, Dallas, San Diego, .... New to the 2004 ACS data, in AFF, are "Subject Tables." This is apparently a work in progress; only subject tables for the U.S. national level for income and poverty are available as of 8/31/05, 8:00 AM. Also new to the 2004 ACS data access in American Factfinder are "Thematic Maps." Right now these are state-level thematic (choropleth) maps for about 80 different themes. It look likes they're setting this up for the eventual production of online maps perhaps for more detailed geographic areas like counties or metro areas. The "Detailed Tables" in the 2004 ACS edition of American Factfinder are greatly expanded from the 2003 ACS and previous years' versions. For example, Table B08006 provides "sex of workers by means of transportation to work" These are the DETAILED means of transportation (including bicycle, carpool level, transit sub-modes"). (The 2003 ACS table, P047, didn't have the workers by sex breakout, or the detailed carpool levels.) To my pleasant surprise, the 2004 ACS PUMS data (Public Use Microdata Sample) was available the first day of release. Data is available in CSV and SAS formats. I'm having some problems with the SAS files, but I'll work that out with our IT people or the Census Bureau. So, there's plenty of work & analysis to do, so just get to it!
