From the Guide to 2010 State and Local Census Geography – Kentucky – History:
The area of Kentucky was originally part of Virginia within the original United States. Virginia ceded the district of Kentucky to the United States in 1792, and this area was included briefly in the Southwest Territory ("territory . . . south of the Ohio River"). Upon resolution of a boundary dispute with Tennessee in 1820, Kentucky assumed generally the same boundary as the present state.
Kentucky is one of four states that are legally described as a commonwealth. Although it was still part of Virginia, census data for Kentucky are available separately beginning with the 1790 census. The population shown for Kentucky in the 1790-1820 censuses is based on the present state boundary, not the territory claimed by Kentucky from Tennessee along its southern boundary. The population of the entire legally established state of Virginia (of which the area of Kentucky was a part) in 1790 was 821,287.
Data for the legally established state of Kentucky are available beginning with the 1800 census, minus claimed territory.
