Census Records

Before Wyoming was a state in 1890, Wyoming was included in the 1850 Utah Territory. In the 1860 Census, it was enumerated as Nebraska Territory. The first Wyoming Territorial Census was taken in 1869, right after Wyoming Territory was created, and is available on microfilm at the Wyoming State Archives[8] and at the Family History Library in Salt Lake City (FHL film 2261365). The 1870 and 1880 Federal Censuses included Wyoming Territory.[9] See links listed below. State censuses were taken for Wyoming but they were mostly statistical censuses with very little individual information. See Wyoming Census for more information.
