What drives Millcreek’s History grade

On its age, its old homes and the National Register, Millcreek is more historic than 52% of U.S. towns, #35 of 119 in Utah. Its National Register listings hold the grade up; its share of homes from before 1940 pulls it down.

Utah towns list more on the Register than most of the country (a typical Utah town has 3.0 per 10,000 residents, the U.S. 2.4), so Millcreek’s 104 sits above most of its state (90% of Utah towns have fewer) while its 660 historic buildings outnumber those of 98% of U.S. towns.

How sure. Graded on any two of the three inputs instead, the letter would range from C− to B+. The pre-1940 share (±0.8 points) is firm at this size. The founding year is the first post office, not a stated founding date; Wikidata gives 2016.

Founding year: the first post office (other dates in Quick answers). Homes: Census ACS 2020–24.

The story

How Millcreek came to be

From Wikipedia’s history of Millcreek.

Read it all →

Early settlers of the Millcreek area in 1848 included Mary Fielding Smith (widow of Hyrum Smith) and her children, including Joseph F. Smith. The area remained essentially rural in character until after World War II. As postwar suburban growth spilled south over the Salt Lake City limits, the area was not annexed by the city and remained unincorporated.
