D−
HistoryA character grade: shown, never part of North Salt Lake’s overall grade.
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 North Salt Lake’s 0.0 sits below most of its state (18% of Utah towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from D− to D. 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 1946.
Founding year: the first post office (other dates in Quick answers). Homes: Census ACS 2020–24.

Wikipedia doesn’t have a history of North Salt Lake yet. The photos, dates and memories neighbors add here are how it gets written.
North Salt Lake is a city in Davis County, Utah, United States. It is part of the Ogden–Clearfield, Utah Metropolitan Statistical Area. The population was 16,322 at the 2010 census, which had risen to 21,907 as of 2020. The city is often casually known as North Salt Lake City as it shares a municipal boundary with Salt Lake City to the south, though the city's actual corporate name is "The City of North Salt Lake". The error also has been solidified with the Federal Communications Commission, which has radio station KALL (700) officially licensed to "North Salt Lake City", though for all intents and purposes that station serves the Salt Lake City market in general.
Its first post office opened in 1917. Between the 2010 and 2020 censuses its population grew from 16,322 to 21,907 (+34%).
