Ohio Boundary, Census, and Statehood History
Ohio was part of the Territory Northwest of the River Ohio, established in 1787 and commonly known as the Northwest Territory. Besides present-day Ohio, it included what are now Indiana, Illinois, Michigan, Wisconsin, and northeastern Minnesota. In 1800, with the creation of Indiana Territory, the Northwest Territory was reduced essentially to present-day Ohio, a small portion of southeastern Indiana, and the eastern half of lower Michigan. Ohio became a separate territory in 1802 and was admitted as a State on March 1, 1803, with its present boundaries except for a much-disputed strip along the northwestern border. This strip was governed by Michigan Territory until finally ceded to Ohio in 1836.
In 1790 the Northwest Territory had no census coverage. The 1800 census enumerated population in much of present-day Ohio and in a portion of southeastern Indiana; the total excludes the then Wayne County, nearly all of whose population was in present-day Michigan. The 1810, 1820, and 1830 censuses covered all of present-day Ohio except for the disputed northwestern strip, which was enumerated as part of Michigan.
