HistoryA character grade: shown, never part of Fenner’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 Fenner’s 5.8 sits near the middle of its state (37% of New York towns have fewer) while its 1 listings outnumber those of 51% of U.S. towns.
