What drives Chesterfield’s History grade

B
HistoryA character grade: shown, never part of Chesterfield’s overall grade.
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 Chesterfield’s 5.2 sits above most of its state (65% of Missouri towns have fewer) while its 26 historic buildings outnumber those of 81% 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 (±1.0 points) is firm at this size. The founding year is the first post office, not a stated founding date; Wikidata’s 1837 falls in the same era, so the grade doesn’t depend on which one is used.
