Dear Everyone: 

We have created a limited set of profile sheets:  National, States, a few large cities, and several Metropolitan Areas.  The profiles include data from 1990 Census, 2000 Census, and the 2005 American Community Survey.  http://ctpp.transportation.org/2005.htm

PLEASE READ THE “NOTES”  which has more information about “GQ: group quarters”  “MOE:  Margin of Error,” and geographic comparison issues.   

The Census Bureau advices data users NOT to make direct comparisons between the ACS and decennial Census results because of changes in survey methods.  However, one of the main uses of the newly released 2005 ACS is to examine trends from 2000. 

If your area was included in the sample of counties (about one-third of counties) in the 2000 ACS C2SS, we recommend that you include both 2000 Census and C2SS results when you analyze changes over time for RESIDENCE GEOGRAPHY.  You will see in the “highlights” documents attached that we have included two bar charts using this approach.

These pages use the 2005 ACS data released on August 29.  We will be working on another set of profile sheets using the 2005 ACS data released on October 3.
