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.
