New and Modified Content on the 2008 ACS Questionnaire: Results of Testing Prior to Implementation

Component ID: #ti1328243636


As a result of the success of the 2006 American Community Survey (ACS) Content Test and the 2007 ACS Grid-Sequential Test, several items were changed in the 2008 ACS production questionnaire. This document summarizes the results of the 2006 ACS Content Test and the 2007 ACS Grid-Sequential Test with a focus on those items that were ultimately changed in production. This document is intended to provide background for people with regard to differences between the 2008 ACS and earlier years. Since the conditions of the test were not exactly the same as production, the information presented here is not meant to predict nor can it fully explain all differences in estimates between the 2008 data and earlier years.
