The informations on the U.S. Federal Census from 1810

Enumerators of the 1810 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 10, 10 to 16, 16 to 26, 26 to 45, 45 and older; number of other free persons except Indians not taxed; number of slaves; and town or district and county of residence. 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. Most entries are arranged in the order of visitation, but some have been rearranged to appear in alphabetical order by initial letter of the surname. Manufacturing schedules are scattered among the 1810 population schedules. This database is certain to prove useful for those seeking early American ancestors.

The United States was the first country to call for a regularly held census. The Constitution required that a census of all "Persons...excluding Indians not taxed" be performed to determine the collection of taxes and the appropriation of seats in the House of Representatives. The first nine censuses from 1790-1870 were organized under the United States Federal Court system. Each district was assigned a U.S. marshal who hired other marshals to administer the census. Governors were responsible for enumeration in territories.

The official enumeration day of the 1810 census was 6 August 1810. All questions asked were supposed to refer to that date. The enumeration was to be completed within nine months, but the due date was extended by law to ten months. Schedules exist for 17 states and District of Columbia, Georgia territory, Mississippi territory, Louisiana territory, Orleans, Michigan territory, and Illinois territory. There was, however, a district wide loss for District of Columbia, Georgia, Indiana Territory, Mississippi Territory, Louisiana Territory (MO), New Jersey and Tennessee. Partial losses included Illinois Territory, which had only two counties (Randolph is extant, St. Clair is lost.), and OH, all lost except Washington County. Some of the schedules for these states have been re-created using tax lists and other records.
