What drives Leyden’s History grade

HistoryA character grade: shown, never part of Leyden’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 Leyden’s 24.1 sits near the middle of its state (59% of New York towns have fewer) while its 4 listings outnumber those of 68% 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 (±8.2 points). The founding year is the first post office, not a stated founding date.

What stands out about Leyden’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Leyden was formed from the town of Steuben (in Oneida County) in 1797. Leyden formed part of a tract called the "Inman Triangle".
The town of Leyden gave up much of its territory to form new towns such as Watson (1821) and Lewis (1852). Leyden was also partitioned to form the towns of Brownville (Jefferson County in 1802) and Boonville (Oneida County in 1805), and part of the town of Wilna (Jefferson County in 1813). Port Leyden in the town was a port on the former Black River Canal.
