Utah was acquired from Mexico in 1848 and established as a territory in September 1850, including most of present-day Nevada and western Colorado. Colorado and Nevada were separated in 1861, with further transfers from Utah to Nevada in 1862 and 1866. Utah acquired its present boundaries in 1868, and was admitted as a State on January 4, 1896.

The 1860 population includes some persons in present-day Wyoming, but excludes counties located in present-day Nevada. The 1870 population excludes Rio Virgin County, which was part of Nevada although enumerated as part of Utah.
