Tennessee Boundary, Census, and Statehood History
The Territory South of the Ohio River, formerly part of North Carolina and sometimes known as the Southwest Territory, was created in 1790. It was admitted as the State of Tennessee on June 1, 1796. Both Territory and State had generally the same boundaries as the present State, except that because of erroneous surveys much of the Tennessee-Kentucky boundary was in dispute for some time; it was not finally resurveyed until 1859. Details of the Tennessee-Virginia boundary were not settled until 1901.
Census coverage in 1790 and 1800 was limited to the northeastern part of Tennessee and the region around Nashville, and coverage did not include the whole State until 1830. The 1790 census of the Southwest Territory actually began at the end of July 1791.
