The American Community Survey (ACS) is a household survey conducted by the United States Census Bureau that collects data from American households as well as households in Puerto Rico. As part of the ongoing reciew of the questions included in the survey, the Census Bureau called for the conduct of about 170 cognitive interviews using the American Community Survey (ACS) Spanish and English Computer Assisted Telephone Interview (CATI) and Spanish and English Computer Assisted Personal Interview (CAPI) data collection instruments. This pretesting research was divided into three separate and independent sections – Section I (Demographic questions also included in the Decennial census), which was completed in August, 2008 (see Goerman, et al., 2009); Section II (Housing questions), completed in April, 2009 (this report); and Section III (Additional person level questions), which was completed in August, 2009 (see Fernández et al., 2009). Each section was pretested in Phases I, II, and III respectively. Two rounds of cognitive interviews were administered for each Phase accordingly.
