Some 2008 ACS race responses of Japanese, Korean, Vietnamese, and "Other Asian" checkboxes were processed incorrectly due to processing changes made to accommodate the race question's new layout in the 2008 questionnaire. These errors were limited to mail forms. Data collected via the telephone and personal visit modes were not affected. We estimate that this error results in the following changes to the national 2008 ACS estimates: increases for the Japanese population (less than 5 percent) and the Asian Indian and Filipino populations (less than 1 percent); and decreases for the Chinese population (less than 3 percent) and the Korean population (less than 2 percent). The Vietnamese population was also impacted by the error described in Errata Note 59, with the net affect being an increase less than half of 1 percent. Additionally, the total for all of the other Asian groups alone or in combination decreases by about 4 percent. This error does not directly impact the national total for the Asian alone population. Given these errors, the 2008 estimates for these populations will not be published in the 2009 ACS Comparison Profiles, and we advise users against making 2009 to 2008 comparisons. We do not plan to rerelease any of the existing 2008 ACS 1-year estimates or the 2006-2008 ACS 3-year estimates on American FactFinder or in the 2008 ACS PUMS files. A very small number of mail returns in 2009 were also processed in error resulting in minor effects on the 2009 ACS 1-year tabulations. No revisions are planned.
