What drives Londonderry’s History grade

HistoryA character grade: shown, never part of Londonderry’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 Londonderry’s 443 sits above most of its state (83% of Vermont towns have fewer) while its 83 historic buildings outnumber those of 88% 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 (±7.1 points). Two sources give 1770.

In forming this union, so desirable, and so necessary to the peace and prosperity of the Parish, each society yielded a few of those peculiarities by which they were distinguished ; and we are happy to find, that they have now become so blended and so unit-
