HistoryA character grade: shown, never part of Columbia Falls’ overall grade.
Montana towns list more on the Register than most of the country (a typical Montana town has 12.7 per 10,000 residents, the U.S. 2.4), so Columbia Falls’ 17.8 sits near the middle of its state (63% of Montana 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 (±4.7 points). The founding year is the first post office, not a stated founding date.
