HistoryA character grade: shown, never part of Flower Hill’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 Flower Hill’s 8.3 sits near the middle of its state (43% of New York towns have fewer) while its 4 historic buildings outnumber those of 68% 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 (±5.6 points). Two sources give 1930.
