What drives Warren’s History grade

On its age, its old homes and the National Register, Warren is more historic than 96% of U.S. towns. All 3 inputs are above most U.S. towns; its share of homes from before 1940 ranks highest and its age lowest.

A+

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 Warren’s 371 sits above most of its state (89% of New York towns have fewer) while its 48 historic buildings outnumber those of 85% 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 (±12.0 points). The founding year is the first post office, not a stated founding date.
