HistoryA character grade: shown, never part of Cecil 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 Cecil Township’s 2.7 sits near the middle of its state (60% of Pennsylvania towns have fewer) while its 4 historic buildings outnumber those of 68% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from B+ to A−. The pre-1940 share is a Census survey estimate (±3.1 points). The founding year is the first post office, not a stated founding date.
