HistoryA character grade: shown, never part of Tiffin 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 Tiffin Township’s 7.6 sits above most of its state (71% of Ohio towns have fewer) while its 4 listings outnumber those of 68% of U.S. towns.
