What drives McAdoo’s History grade
On its age, its old homes and the National Register, McAdoo is more historic than 55% of U.S. towns. Its share of homes from before 1940 holds the grade up; its National Register listings pull it down.
B−
HistoryA character grade: shown, never part of McAdoo’s overall grade.
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 McAdoo’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.
How sure. Graded on any two of the three inputs instead, the letter would range from C− to B+. The pre-1940 share is a Census survey estimate (±7.7 points). The founding year is the first post office, not a stated founding date; Wikidata’s 1896 falls in the same era, so the grade doesn’t depend on which one is used.
