HistoryA character grade: shown, never part of Troy 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 Troy Township’s 4.1 sits near the middle of its state (61% of Ohio towns have fewer) while its 1 listings outnumber those of 51% of U.S. towns.
How sure. Graded on two of the three inputs, so a change in either one moves the letter more than it would with three. The pre-1940 share is a Census survey estimate (±7.7 points).
