What drives Spencer Township’s History grade

On its age, its old homes and the National Register, Spencer Township is more historic than 81% of U.S. towns, #301 of 993 in Ohio. All 2 inputs are above most U.S. towns; its share of homes from before 1940 ranks highest and its National Register listings lowest.

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 Spencer Township’s 3.3 sits near the middle of its state (57% 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 (±7.3 points).
