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. 1950 is the most recent population schedule available.


"Return of the whole number of persons within the several districts of the United States" features population data by race, condition of servitude, State, county, and town for the 1800 census. Also includes data by sex for free white persons, and by age group for males.
