B+
HistoryA character grade: shown, never part of Britton’s overall grade.
South Dakota towns list more on the Register than most of the country (a typical South Dakota town has 37.3 per 10,000 residents, the U.S. 2.4), so Britton’s 30.4 sits above most of its state (65% of South Dakota towns have fewer) while its 3 listings outnumber those of 65% 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 (±12.8 points). The founding year is the first post office, not a stated founding date.
