In 1795 a territorial census was taken. The results of that census showed that residency in the area had doubled in 4 years time and that the requirements for statehood had been met. Early settler petitions can fill in some missing census information. Several societies and journals have published those petitions. Early tax lists from the state can also fill in missing data.
There are federal census records from 1820 available for 26 of the counties in Tennessee. Those counties are: Bedford, Davidson, Dickson, Franklin, Giles, Hardin, Hickman, Humphreys, Jackson, Lawrence, Lincoln, Maury, Montgomery, Overton, Perry, Robertson, Rutherford, Shelby, Smith, Stewart, Sumner, Warren, Wayne, White, Wilson, and Williamson. A complete list of Tennessee households does not exist, except for Grainger, for any years prior to 1830.
