Several minor errors were discovered in the 2008 ACS edit programs for a number of variables including age, citizenship status, employment status, household language, income, industry and occupation, race and Hispanic origin, real estate taxes included in mortgage payment, and second mortgage. In each case, the edit programs were not completely updated to reflect variable changes resulting from the addition of three new questions and the revision of twelve other questions in 2008. This error affects almost every table but the effect is very small. Corrected 2008 data will appear in the 2009 ACS 1-year Comparison Profiles. Corrected 2008 data will also be used to produce the 2005-2009 ACS 5-year and 2007-2009 ACS 3-year data products as well as future multiyear products. We do not plan to rerelease any of the existing 2008 ACS 1-year or 2006-2008 ACS 3-year tables on American FactFinder, or the 2008 or 2006-2008 ACS PUMS files.
