B+
HistoryA character grade: shown, never part of Kahoka’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 Kahoka’s 14.5 sits above most of its state (76% of Missouri 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 (±7.6 points). Two sources give 1858.
