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. Below are links to print and on-line versions of the population schedules. The library also has selected population schedules available on microfilm.
