What drives Sumner’s History grade
On its age, its old homes and the National Register, Sumner is more historic than 82% of U.S. towns. All 3 inputs are above most U.S. towns; its age ranks highest and its National Register listings lowest.

HistoryA character grade: shown, never part of Sumner’s overall grade.
Maine towns list more on the Register than most of the country (a typical Maine town has 15.9 per 10,000 residents, the U.S. 2.4), so Sumner’s 23.7 sits near the middle of its state (63% of Maine towns have fewer) while its 2 listings outnumber those of 60% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would still be A−. The pre-1940 share is a Census survey estimate (±10.0 points). Two sources give 1798.
