Census records for Arizona are available for 1864 and 1866, long before it became a state. The Arizona State Archives has the original 1864 census records, copies of those records, and microfilmed versions of them. It also houses information from the 1882 census for Yuma, Yavapai, Gila, Pima, Mohave, Cochise, Graham, and Maricopa counties.
The “great registers” of voters can be used to learn a lot of information in a similar way to how tax records or census records would be used. The FHL has many of those voter registers available on microfilm and several can also be found at the Arizona State Archives.
That includes records for the following counties: Apache (1884-1910), Cochise (1882-1910), Coconino (1894-1910), Gila (1882-1910), Graham (1882-1911), Maricopa (1876-1938), Mohave (1866-82), Navajo (1895-1932), Pima (1876-1913), Pinal (1894-1911), Santa Cruz (1902-35), Yuma (1882-1910), Yavapai (1882-1906).
The 1890 federal census records for Arizona have been lost, but the 1890 Great Register for Arizona Territory still exist and has been published and indexed by the Arizona Genealogical Advisory Board. It’s important to note that only white males over 21 years old were included on those voter lists until African Americans and females were added in 1913. It wasn’t until 1948 that Native Americans were also added.
