On its age, its old homes and the National Register, Leet Township is more historic than 53% of U.S. towns. Its share of homes from before 1940 holds the grade up; its National Register listings pull it down.
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 Leet 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.

Originally part of Pitt Township and the Depreciation Lands, reserved for Revolutionary War veterans, it was named after Jonathan Leet, a surveyor who laid out the town of Beaver Falls.
