HistoryA character grade: shown, never part of Mifflin 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 Mifflin 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 (±7.8 points).

The first European settlers probably arrived in the area that is now Mifflin Township in the late 1770s, although the exact date cannot be determined. In 1799, the township was formed from part of Catawissa Township and named for Thomas Mifflin, governor of Pennsylvania. Mifflin Township historically did not have much industrial business, because of the lack of transportation until the construction of the North and West Branch Railroad. However, a gunpowder factory was erected in the township in 1855, although it was destroyed less than three days later in an explosion.
