What drives Evansville’s History grade

On its age, its old homes and the National Register, Evansville is more historic than 11% of U.S. towns, #25 of 28 in Wyoming. Its share of homes from before 1940 holds the grade up; its age pulls it down.

Wyoming towns list more on the Register than most of the country (a typical Wyoming town has 25.1 per 10,000 residents, the U.S. 2.4), so Evansville’s 0.0 sits below most of its state (16% of Wyoming towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.

How sure. Graded on any two of the three inputs instead, the letter would range from D− to C−. The pre-1940 share is a Census survey estimate (±4.4 points). The founding year is the first post office, not a stated founding date.

Founding year: the first post office (other dates in Quick answers). Homes: Census ACS 2020–24.
