Thanks to Charles Baber from Baltimore Metropolitan Council for researching a problem with household income values using the 2008 ACS PUMS. Here is a useful link to CB website on errata: http://www.census.gov/acs/www/UseData/Errata.htm <http://www.census.gov/acs/www/UseData/Errata.htm> And just in case you missed our April 2009 training on IPUMS, the web-training session is still available at http://fhwa.na3.acrobat.com/p25106595/ Elaine
