More historic than 76% of U.S. towns, on its age, its old homes and the National Register.
On its age, its old homes and the National Register, Jackson Township is more historic than 76% of U.S. towns, #381 of 1,035 in Pennsylvania. All 2 inputs are above most U.S. towns; its National Register listings ranks highest and its share of homes from before 1940 lowest.
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 Jackson Township’s 20.4 sits above most of its state (82% of Pennsylvania towns have fewer) while its 19 historic buildings outnumber those of 79% of U.S. towns.
