Pew Reports: "For the 2020 census, the bureau is testing whether government records could supply basic details about 6 million hard-to-count households, and be used to identify another 6 million vacant homes so door-to-door enumerators can save time by skipping them during follow-up on homes that did not send in census forms. The agency also is researching whether such records could be a substitute for some questions, especially about sensitive topics such as income, on the American Community Survey, which replaced the census long form in 2010."
