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 Hereford Township’s 39.4 sits above most of its state (85% of Pennsylvania towns have fewer) while its 12 historic buildings outnumber those of 77% of U.S. towns.
