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 Castle Dale’s 64.7 sits above most of its state (87% of Utah towns have fewer) while its 10 historic buildings outnumber those of 76% 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 (±5.6 points). Two sources give 1877.
