The Census Bureau just released the first of a series of "handbooks" aimed at helping data users negotiate their way through ACS data. This first handbook, "What General Data Users Need to Know" will help general audiences understand the basics of the ACS, its opportunities and challenges, and how to access and use the ACS data on the Census Bureau's Web site. The handbook can be found at http://www.census.gov/acs/www/Downloads/ACSGeneralHandbook.pdf The handbook itself is part of a much broader suite of e-learning ACS materials that can found at http://www.census.gov/acs/www/UseData/Compass/compass_series.html In addition, NCHRP Report 588 "A Guidebook for Using the American Community Survey Data for Transportation Planning" is a MUST HAVE for the transportation planner. It can be found on-line at http://onlinepubs.trb.org/onlinepubs/nchrp/nchrp_rpt_588.pdf -- Ed Christopher Resource Center Planning Team Federal Highway Administration 19900 Governors Drive Olympia Fields, Illinois 60461 708-283-3534 (V) 708-574-8131 (cell) 708-283-3501 (F)
