More historic than 50% of U.S. towns, on its age, its old homes and the National Register.
On its age, its old homes and the National Register, Colerain Township is more historic than 50% 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 Colerain 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.
