What drives Big Sky’s History grade

On its age, its old homes and the National Register, Big Sky is more historic than 38% of U.S. towns. Its National Register listings hold the grade up; its share of homes from before 1940 pulls it down.

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 Big Sky’s 45.0 sits above most of its state (71% of Montana towns have fewer) while its 11 historic buildings outnumber those of 76% of U.S. towns.

How sure. Graded on two of the three inputs, so a change in either one moves the letter more than it would with three. The pre-1940 share (±0.8 points) is firm at this size.
