HistoryA character grade: shown, never part of Ralpho 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 Ralpho Township’s 7.2 sits above most of its state (72% of Pennsylvania towns have fewer) while its 3 listings outnumber those of 65% of U.S. towns.
