HistoryA character grade: shown, never part of Sheridan’s overall grade.
Arkansas towns list more on the Register than most of the country (a typical Arkansas town has 20.5 per 10,000 residents, the U.S. 2.4), so Sheridan’s 17.4 sits near the middle of its state (52% of Arkansas towns have fewer) while its 9 historic buildings outnumber those of 75% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from C to B−. The pre-1940 share is a Census survey estimate (±3.9 points). The founding year is the first post office, not a stated founding date.
