The Census 2000 Supplementary Survey was designed to demonstrate the feasibility of collecting long form-type information at the same time but separately from the decennial census. It used the American Community Survey questionnaire to collect demographic, social, economic, and housing data from a sample of 700,000 households nationwide.
