What drives Lyndon’s History grade

HistoryA character grade: shown, never part of Lyndon’s overall grade.
Vermont towns list more on the Register than most of the country (a typical Vermont town has 147 per 10,000 residents, the U.S. 2.4), so Lyndon’s 17.9 sits below most of its state (33% of Vermont towns have fewer) while its 10 listings outnumber those of 76% 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 (±6.6 points). The founding year is the first post office, not a stated founding date.

The Lyndon post office opened in 1811, the earliest record of the town by name (U.S. post office records).
