Minnesota Territorial & State Census
Since 1820 people living in what is now Minnesota have been enumerated in various state and territorial censuses:
Some Minnesota inhabitants were included in the 1820 territorial census of Michigan and the 1836 census of the Wisconsin Territory.
The first Minnesota Territorial Census was taken in 1849, and was taken again in 1850, 1853, 1855, and 1857.
After statehood was granted in 1858, the Minnesota State Census was taken every 10 years, in years that ended with a 5: 1865, 1875, 1885, 1895, and 1905.
1905 was the last year of the Minnesota State Census.
