HistoryA character grade: shown, never part of Susquehanna 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 Susquehanna 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 (±6.8 points).

Susquehanna Township was incorporated on January 6, 1825, being formed from Allegheny and Cambria Townships. In addition to agriculture, the ready local supply of lumber attracted people to the area in the early 19th century. Much of this was transported down the West Branch Susquehanna River to lumber towns such as Williamsport. In the late 19th century, the arrival of the railroad opened up the area to coal mining. The subsequent mining boom created many jobs, attracting a large number of people to settle in the area of Susquehanna Township, many of whom remained with their families after the boom had ended.
Susquehanna Township is more historic than 62% of U.S. towns. The History grade combines the town’s founding era, the share of homes built before 1940 and its National Register listings. It’s a character grade, so it isn’t part of the overall grade. How it works.
