I hope that everyone is enjoying looking at the new data from ACS. Most of the articles I've glanced at today have been about the diversity of people in suburbs, and the growth in non-English speaking populations. Since I have received several additional queries about the materials from last week's web training, here is one more email: FHWA 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/ If you are interested in the powerpoint presentations, you can go into the meeting room http://fhwa.na3.acrobat.com/ctpp1 as a GUEST, and download the files. The Census Bureau has shapefiles available: http://www.census.gov/geo/www/tiger/tgrshp2007/tgrshp2007.html Also, IPUMS has PUMA boundaries that are more detailed than the Census Bureau version. http://usa.ipums.org/usa/volii/2000pumas.shtml Elaine Murakami FHWA Office of Planning (Wash DC) 206-220-4460 (Seattle)
