What drives Champlain’s History grade
On its age, its old homes and the National Register, Champlain is more historic than 84% of U.S. towns, #361 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 National Register listings lowest.
A−
HistoryA character grade: shown, never part of Champlain’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 Champlain’s 7.1 sits near the middle of its state (40% 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 B+ to A. The pre-1940 share is a Census survey estimate (±4.2 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.

Nearby Lake Champlain was an important military and trade route during the colonial period. The lake and the town were named in honor of Samuel de Champlain, who first surveyed the area in 1609. It was part of Canada until 1763 and became part of the United States in 1783.
The town was formed in 1788, the same year the county was established. In 1799, the town was reduced by the formation of the town of Chateaugay (now in Franklin County). The founding of the towns of Chazy and Mooers, in 1804, further reduced Champlain.
Fire insurance maps drew every building, what it was made of and what it was used for, so insurers could price the risk of fire. Pick a year, then a sheet.
The Champlain post office opened in 1810, the earliest record of the town by name (U.S. post office records).
