What drives New Haven Township’s History grade
On its age, its old homes and the National Register, New Haven Township is more historic than 64% of U.S. towns. Its share of homes from before 1940 holds the grade up; its National Register listings pull it down.
B
HistoryA character grade: shown, never part of New Haven 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 New Haven Township’s 0.0 sits below most of its state (23% of Ohio towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from C+ to A−. The pre-1940 share is a Census survey estimate (±8.8 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. National Register: National Park Service, May 2026 list; each listing counted once (boundary changes and added documentation belong to their listing), and a historic district counts its contributing buildings.
