What drives Columbus’ History grade
On its age, its old homes and the National Register, Columbus is more historic than 66% of U.S. towns. Its share of homes from before 1940 holds the grade up; its age pulls it down.
B+
HistoryA character grade: shown, never part of Columbus’ 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 Columbus’ 25.0 sits above most of its state (66% of Montana towns have fewer) while its 5 listings outnumber those of 70% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from B− to A−. The pre-1940 share is a Census survey estimate (±5.5 points). The founding year is the first post office, not a stated founding date.
