A+
HistoryA character grade: shown, never part of Kinsman Township’s overall grade.
Ohio towns list about as much on the Register as the country (a typical Ohio town has 2.9 per 10,000 residents, the U.S. 2.4), so Kinsman Township’s 36.1 sits above most of its state (86% of Ohio towns have fewer) while its 6 historic buildings outnumber those of 72% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from A− to A+. The pre-1940 share is a Census survey estimate (±18.4 points). The founding year is the first post office, not a stated founding date.
Founding year: the first post office (other dates in Quick answers). Homes: Census ACS 2020–24.
