What drives Avalon’s History grade

On its age, its old homes and the National Register, Avalon is more historic than 87% of U.S. towns, #228 of 1,035 in Pennsylvania. All 3 inputs are above most U.S. towns; its share of homes from before 1940 ranks highest and its National Register listings 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 Avalon’s 2.1 sits near the middle of its state (58% of Pennsylvania towns have fewer) while its 1 listings outnumber those of 51% of U.S. towns.

NoteThe founding year comes from Wikidata alone; no second source gives 1800.

On December 9, 1874, a group of 29 property owners met and decided they wanted to separate from Kilbuck Township, which itself split from Pine Township in 1869. They petitioned the Court of Quarter Sessions of Pennsylvania for incorporation papers. The petition was drawn up by Noah Shafer, who eventually became West Bellevue's first solicitor.
