Millcreek: From Unincorporated Suburb to Salt Lake County City

Millcreek is a city in Salt Lake County and part of the Salt Lake City metropolitan area. The city had 63,380 residents in the 2020 census, according to the supplied background material. Although Millcreek is now an incorporated municipality, its governmental history is relatively recent: it became a city on December 28, 2016.

Before incorporation, the area existed as an unincorporated township and, at different points, as a census-designated place. That distinction matters because the community’s identity and statistical boundaries changed over time. The area now associated with Millcreek was not always counted as a single place.

Settlement in the area began in 1848. Among the early settlers were Mary Fielding Smith, the widow of Hyrum Smith, and her children, including Joseph F. Smith. For many years, the area retained a largely rural character. That changed after World War II, when suburban development expanded southward beyond Salt Lake City’s boundaries.

Millcreek did not become part of Salt Lake City through annexation. Instead, it remained unincorporated as postwar growth transformed the landscape. By the 1980s, most of the area had been developed. Residents and others used several names for different parts of the community, including East Mill Creek, Canyon Rim and Mount Olympus.

The changing names also reflected how the area was handled in census records. In 2000, the area was divided among four census-designated places. The westernmost was called Millcreek and had 30,377 residents at that census. It covered 4.9 square miles, or 12.8 square kilometers.

For the 2010 census, Canyon Rim, East Millcreek and Mount Olympus were consolidated with Millcreek for statistical purposes. The resulting census-designated place had 62,139 residents, roughly twice the population recorded for the Millcreek CDP in 2000. The later incorporation of the broader community created a city from an area that had long functioned as a developed suburban population center without being part of Salt Lake City.

Today, Millcreek’s civic story is therefore one of consolidation and formalization. Its population center grew through suburban expansion, while its official labels shifted from township and separate census-designated places to a single city. For Salt Lake County residents, the history provides context for why familiar community names can coexist with the municipal name Millcreek: those names reflect earlier geographic and statistical identities within the area that was incorporated in 2016.
