The U.S. Census Bureau conducts several data collection programs about the U.S. population which have their own language, geography, and data portals. This guide is based on a similar guide created by Kelly Smith at UCSD.

Population Schedules

Census population schedules (or "name schedules" or "manuscript census") are copies of the original questionnaires collected during each decennial census. They list the individual names and family information of the people enumerated. Unlike the statistics published soon after the census, the population schedules remain confidential for 72 years. 1930 is the most recent population schedule available.
