1840 U.S. Federal Census
This database details those persons enumerated in the 1840 United States Federal Census, the Sixth Census of the United States. In addition, the names of those listed on the population schedule are linked to the actual images of the 1840 Federal Census, copied from the National Archives and Records Administration microfilm, M704, 580 rolls. (If you do not initially find the name on the page that you are linked to, try a few pages forward or backward, as sometimes different pages had the same page number.)

Enumerators of the 1840 census were asked to include the following categories in the census: name of head of household, number of free white males and females in age categories: 0 to 5, 5 to 10, 10 to 15, 15 to 20, 20 to 30, 30 to 40, 40 to 50, 50 to 60, 60 to 70, 70 to 80, 80 to 90, 90 to 100, over 100; the name of a slave owner and the number of slaves owned by that person; the number of male and female slaves by age categories; the number of foreigners (not naturalized) in a household; and the number of deaf, dumb and blind persons within a household. Additionally, the 1840 census asked for the first time the ages of revolutionary war pensioners, as well as the number of persons attending school. The categories allowed Congress to determine persons residing in the United States for collection of taxes and the appropriation of seats in the House of Representatives.
