What drives Geneseo’s History grade
On its age, its old homes and the National Register, Geneseo is more historic than 95% of U.S. towns, #151 of 758 in New York. All 3 inputs are above most U.S. towns; its National Register listings ranks highest and its age lowest.

HistoryA character grade: shown, never part of Geneseo’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 Geneseo’s 551 sits above most of its state (92% of New York towns have fewer) while its 424 historic buildings outnumber those of 97% 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 (±5.9 points). Two sources give 1789.

■Gerrit Smith delivered an address at a meeting held at the Presbyterian Church in Geneseo, on the 1st day of September, 1838. At this meeting, according to the record, "there was a respectable audience from several towns in the county, and among them a fciv from the Village of Geneseo." It is apparent from the emphasis with which the secretary records the word "few," that the attendance from Geneseo was not up to his notion of what it should have been.
