What drives Colesville’s History grade
On its age, its old homes and the National Register, Colesville is more historic than 82% of U.S. towns, #392 of 758 in New York. Its share of homes from before 1940 holds the grade up; its National Register listings pull it down.
A−
HistoryA character grade: shown, never part of Colesville’s overall grade.
New York towns list more on the Register than most of the country (a typical New York town has 12.3 per 10,000 residents, the U.S. 2.4), so Colesville’s 4.2 sits below most of its state (32% of New York towns have fewer) while its 2 listings outnumber those of 60% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from B to A. The pre-1940 share is a Census survey estimate (±7.1 points). The founding year is the first post office, not a stated founding date; Wikidata’s 1821 falls in the same era, so the grade doesn’t depend on which one is used.
Founding year: the first post office (other dates in Quick answers). Homes: Census ACS 2020–24.
