From the Guide to 2010 State and Local Census Geography — Tennessee — History:

The area of Tennessee was originally part of North Carolina. North Carolina ceded the area of Tennessee in 1790 to the United States, and this area was organized as the “territory . . . south of the Ohio River” on April 12, 1790. Tennessee was admitted to the Union on June 1, 1796, as the 16th state. Upon resolution of a boundary dispute with Kentucky in 1820, Tennessee assumed generally the same boundary as the present state.

Census data for Tennessee are available separately beginning with the 1790 census. The 1790 population shown for Tennessee is for the Southwest Territory, which generally had the present state boundary.

Data for the legally established state of Tennessee are available beginning with the 1800 census.
