What drives New Windsor’s History grade

On its age, its old homes and the National Register, New Windsor is more historic than 68% of U.S. towns, #541 of 758 in New York. Its age holds the grade up; its share of homes from before 1940 pulls it down.

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 New Windsor’s 4.3 sits below most of its state (33% of New York towns have fewer) while its 12 historic buildings outnumber those of 77% of U.S. towns.

How sure. Graded on any two of the three inputs instead, the letter would range from C+ to A−. The pre-1940 share (±1.6 points) is firm at this size. Two sources give 1763.
