What drives Milo’s History grade
On its age, its old homes and the National Register, Milo is more historic than 97% of U.S. towns, #74 of 758 in New York. All 3 inputs are above most U.S. towns; its share of homes from before 1940 ranks highest and its age lowest.
A+
HistoryA character grade: shown, never part of Milo’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 Milo’s 336 sits above most of its state (88% of New York towns have fewer) while its 229 historic buildings outnumber those of 94% 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 (±5.8 points). The founding year is the first post office, not a stated founding date.
Founding year: the first post office (other dates in Quick answers). Homes: Census ACS 2020–24.

The region was within the realm of the Seneca tribe before Europeans entered the area.
Settlement began around 1788 by members of the Universal Friends, a religious sect. In 1818, the town was founded from part of the Town of Benton, while still part of Ontario County. By 1820, the population was about 1,612. When Yates county was formed in 1823, Milo became part of the new county.
In 1833, the Village of Penn Yan was incorporated, setting itself apart from the town.
The Crooked Lake Canal ran partly across the northern part of Milo when it opened in 1833. Around 1877, the canal ceased to function and its lands were taken over by railroads.
