What drives Union’s History grade
On its age, its old homes and the National Register, Union is more historic than 92% of U.S. towns, #221 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 Union’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 Union’s 35.8 sits near the middle of its state (64% of New York towns have fewer) while its 197 historic buildings outnumber those of 93% 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 (±2.5 points) is firm at this size. Two sources give 1791.

The region was first settled by Americans/Europeans circa 1782.
During the American Revolution, detachments of soldiers were sent through this region with the intent of attacking natives who were friendly to the British. Documented attacks on native villages in present-day Binghamton, Vestal, and Choconut Township, Pennsylvania, indicate that many natives were killed in these incursions in 1779.
