What drives Osakis’ History grade

Minnesota towns list about as much on the Register as the country (a typical Minnesota town has 2.1 per 10,000 residents, the U.S. 2.4), so Osakis’ 6.2 sits above most of its state (67% of Minnesota towns have fewer) while its 1 listings outnumber those of 51% of U.S. towns.

How sure. Graded on any two of the three inputs instead, the letter would range from C+ to A−. The pre-1940 share is a Census survey estimate (±6.0 points). The founding year is the first post office, not a stated founding date; Wikidata’s 1866 falls in the same era, so the grade doesn’t depend on which one is used.
