Wisconsin Boundary, Census, and Statehood History
Wisconsin was part of the Northwest Territory organized in 1787, then of Indiana Territory (1800). In 1809 it was included in the new Illinois Territory, except for the northern part of the Door Peninsula, which remained in Indiana Territory. In 1818 Michigan Territory expanded to include the whole of present-day Wisconsin. Wisconsin Territory was organized in 1836 and briefly included all of Minnesota and Iowa and the Dakotas east of the Missouri River. After Iowa Territory was organized in 1838, only northeastern Minnesota, east of the Mississippi River and a line from its source north to the Canadian boundary, remained in Wisconsin Territory. Wisconsin was admitted as a State on May 29, 1848 with essentially its present boundaries.
There was only limited census coverage of the present area of the State prior to 1840. In 1790 the Northwest Territory had no census coverage. The 1800 census for Indiana Territory reported populations for Green Bay (50) and Prairie du Chien (65); in 1810 any settlers enumerated in these or other Wisconsin communities were reported as part of St. Clair County, Illinois Territory. In 1820 Crawford and Brown Counties, Michigan Territory, included nearly all of present-day Wisconsin; Crawford also included northeastern Minnesota but this had no census coverage. This also was the case in 1830, with the addition of Iowa County from part of Crawford. In 1840 some persons in northeastern Minnesota were enumerated in St. Croix County, Wisconsin Territory.
