Pennsylvania towns list about as much on the Register as the country (a typical Pennsylvania town has 2.1 per 10,000 residents, the U.S. 2.4), so Todd Township’s 74.9 sits above most of its state (87% of Pennsylvania towns have fewer) while its 13 historic buildings outnumber those of 77% 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 (±6.1 points).
