On its age, its old homes and the National Register, Penn Township is more historic than 33% of U.S. towns, #916 of 1,035 in Pennsylvania. Its share of homes from before 1940 holds the grade up; its National Register listings pull it down.

HistoryA character grade: shown, never part of Penn Township’s overall grade.
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 Penn Township’s 0.0 sits below most of its state (25% of Pennsylvania towns have fewer) while its 0 listings outnumber those of 23% 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 (±5.7 points).
