Indiana Boundary, Census, and Statehood History
Indiana was included in the Northwest Territory (1787) but became a separate territory in 1800. At that time, in addition to most of present-day Indiana, the Territory included all of Illinois and Wisconsin, the western half of Michigan, and northeastern Minnesota. In 1802 the boundary with Ohio was altered and Eastern Michigan was added, but Michigan Territory was separated in 1805 and Illinois Territory in 1809, leaving Indiana Territory with the present State area except for a narrow band along the northern border; the territory also included a portion of the Michigan Upper Peninsula.
On December 11, 1816 Indiana was admitted as a State with essentially its present boundaries. However, even though it was admitted as a state to the US in 1816, the earliest population figures can actually be traced back to 1800.
In 1790 the Northwest Territory had no census coverage. The 1800 census of Indiana Territory enumerated scattered communities in southern Indiana, southwestern Illinois, northern Michigan, and Wisconsin; the populations reported from present-day Illinois and Michigan are shown under those States. In addition, Hamilton County, Ohio included some population in what is now Indiana. In 1810, census coverage of Indiana Territory was limited to southern Indiana, and coverage did not include the whole State until 1830.
