What drives Coeymans’ History grade
On its age, its old homes and the National Register, Coeymans is more historic than 93% of U.S. towns, #188 of 758 in New York. All 3 inputs are above most U.S. towns; its National Register listings ranks highest and its age lowest.
A
HistoryA character grade: shown, never part of Coeymans’ 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 Coeymans’ 352 sits above most of its state (88% of New York towns have fewer) while its 255 historic buildings outnumber those of 95% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from A− to A. The pre-1940 share is a Census survey estimate (±6.3 points). The founding year is the first post office, not a stated founding date.
