What drives La Monte’s History grade

On its age, its old homes and the National Register, La Monte is more historic than 29% of U.S. towns. Its share of homes from before 1940 holds the grade up; its National Register listings pull it down.

Missouri towns list about as much on the Register as the country (a typical Missouri town has 2.4 per 10,000 residents, the U.S. 2.4), so La Monte’s 0.0 sits below most of its state (23% of Missouri 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 C− to C+. The pre-1940 share is a Census survey estimate (±6.4 points). The founding year is the first post office, not a stated founding date.
