What drives Hartford Township’s History grade
On its age, its old homes and the National Register, Hartford Township is more historic than 85% of U.S. towns. All 3 inputs are above most U.S. towns; its share of homes from before 1940 ranks highest and its National Register listings lowest.
A
HistoryA character grade: shown, never part of Hartford 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 Hartford Township’s 10.0 sits above most of its state (74% of Ohio towns have fewer) while its 2 historic buildings outnumber those of 60% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would still be A−. The pre-1940 share is a Census survey estimate (±8.6 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.
