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.

What stands out about Millcreek’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
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.
