More historic than 49% of U.S. towns, on its age, its old homes and the National Register.
On its age, its old homes and the National Register, St. Clair Township is more historic than 49% of U.S. towns. Its National Register listings hold the grade up; its share of homes from before 1940 pulls 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 St. Clair Township’s 8.0 sits above most of its state (74% of Pennsylvania towns have fewer) while its 1 listings outnumber those of 51% of U.S. towns.

Each neighbor’s History grade, on the same three inputs.
St. Clair Township is more historic than 49% 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.
One place: the Laurel Hill Furnace (listed 1975).
7% of St. Clair Township’s homes were built before 1940 (Census estimate, ±2.5 points), against a typical 18% for a Pennsylvania town; the median home was built in 1971.
