The 1800 census was initiated on August 4, 1800 and was taken over a 9-month period of time. The 1800 census contains listings of free white females and males according to age groups. Those groups divided as:
those under 10 years old
those between 10 and 16
those between 16 and 26
those who were 26 to 45
those over the age of 45 at the time that the census was taken.
The 1800 census listed each head of household, the number of free persons in the household and the number of slaves in the household. The district and county of residence were also listed along with each household’s information.
Unique Features of the 1800 Census
Native American Population – As in the 1790 census, Native Americans who were not taxed were not listed on the census forms. Because Native Americans were not eligible to hold a seat in the US House of Representatives, their population was not considered relevant to the purpose of the 1800 census.
Inconsistency of Format – As of 1800, there was not a standard form for recording census information. Therefore, records vary widely in format. Some have been re-ordered alphabetically, which hinders the ability to establish who an ancestor’s neighbors were.
Historical Considerations of the 1800 Census
Slave Information – Slaves are listed according to the last names of their owners. This information can be compared to tax list data and probate inventories to determine names and birth orders of family members.
