Since its inception, the American Community Survey (ACS) has collected data using three modes: mailout/mailback of a paper questionnaire, Computer-Assisted Telephone Interview and Computer-Assisted Personal Interview. In general, sampled addresses receive the mail questionnaire first and are later eligible to be contacted by Computer-Assisted Telephone Interview and then as part of Computer-Assisted Personal Interview nonresponse follow-up operations. The U.S. Census Bureau conducted two ACS Internet tests in 2011 - one in April and one in November -€” to evaluate the feasibility of providing an Internet mode as fourth response mode to addresses selected for the ACS. The main objective of the tests was to determine the best way to present the Internet mode in the ACS mailings to maximize self-administered response. This report focuses on results from the November test.
