HistoryA character grade: shown, never part of Mendon’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 Mendon’s 94.5 sits above most of its state (89% of Utah towns have fewer) while its 14 historic buildings outnumber those of 78% 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 is a Census survey estimate (±5.1 points). Two sources give 1859.
