2008 ACS 1-Year and 2006-2008 ACS 3-Year Estimates for Number of Rooms and Number of Bedrooms Items

An error was discovered in the 2008 ACS 1-year data and the 2006-2008 ACS 3-year data, which involved Question 7 on the housing section (number of rooms and number of bedrooms items) on the 2008 ACS questionnaire . For housing units where data were collected via a computer-assisted telephone interview or a computer-assisted personal interview, if the number of rooms was missing a value of one room and zero bedrooms was erroneously assigned (instead of being imputed from the entire distribution of responses). Approximately 3 percent of all housing units at the national level are affected. The impact is greater on vacant housing units (about 22 percent affected) than occupied housing units (about 0.3 percent affected). A headnote (including a link to this errata note) is included on all of the affected tables.
