More historic than 70% of U.S. towns. What drives it
Most of Penn Township was built recently: 10% of its homes predate 1940 and the median home dates from 1979. Below: maps from 1917 on.
More historic than 70% of U.S. towns, on its age, its old homes and the National Register.
On its age, its old homes and the National Register, Penn Township is more historic than 70% of U.S. towns. Its National Register listings hold the grade up; its share of homes from before 1940 pulls it down.
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 Penn Township’s 31.8 sits above most of its state (85% of Ohio towns have fewer) while its 5 historic buildings outnumber those of 70% of U.S. towns.

Penn Township is more historic than 70% of U.S. towns. The History grade combines the town’s founding era, the share of homes built before 1940 and its National Register listings. It’s a character grade, so it isn’t part of the overall grade. How it works.
One place: the Gist Settlement Historic District (listed 2024).
10% of Penn Township’s homes were built before 1940 (Census estimate, ±6.3 points), against a typical 15% for an Ohio town; the median home was built in 1979.
