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 Old Brookville’s 0.0 sits below most of its state (10% of New York towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.

How sure. Graded on two of the three inputs, so a change in either one moves the letter more than it would with three. The pre-1940 share is a Census survey estimate (±4.7 points).
