Kansas became a territory in 1854 and the first territory census taken was in 1855. It was also enumerated as Kansas Territory in the 1860 Federal Census, although there were 15 counties that were marked with "no population" in them. The state continued to take state censuses after it was admitted to the Union in 1861.[7] See links listed below.

Ward Divisions of the City of LeavenworthEdit

The city of Leavenworth was divided into wards for several federal and state censuses (four wards in the censuses of 1860, 1865, 1870, and 1885; six wards in the censuses of 1895, 1900, 1910, 1920, and 1940). The 1880 census used nine Enumeration Districts, and the 1930 census used ten EDs. The 1875 census reported the entire city in a single unit.

Additional material is under research to identify the boundaries of these wards.
