Census Bureau to Offer American Community Survey Internet Response, press release (MONDAY, DEC. 17, 2012)

The American Community Survey, the most detailed portrait of America's towns and neighborhoods, is now more convenient for most participants with the added availability of responding online. That will make it the 61st U.S. Census Bureau survey with Internet response...

Households selected to participate in the American Community Survey will receive a letter in the mail with instructions about how to log in to the secure website and complete the survey online... If households selected to participate in the survey do not use the online response option, the Census Bureau will send them a paper questionnaire, or contact them by phone or in person to obtain answers.
