ACS Handbook of Questions and Current Federal Uses


Since the founding of the nation, the U.S. Census has mediated between the demands of a growing country for information about its economy and people, and the people’s privacy and freedom from undue intrusion. This handbook provides an overview of the questions asked by the U.S. Census Bureau’s American Community Survey (ACS). The purpose is to help explain why specific questions on the ACS are asked, which estimates are created from the answers to these questions, and how federal agencies and other organizations use these estimates.
