HistoryA character grade: shown, never part of Lower Windsor 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 Lower Windsor Township’s 2.6 sits near the middle of its state (60% of Pennsylvania towns have fewer) while its 2 listings outnumber those of 60% 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 (±5.6 points).
