What drives Dexter’s History grade
On its age, its old homes and the National Register, Dexter is more historic than 81% of U.S. towns, #74 of 143 in Maine. All 3 inputs are above most U.S. towns; its age ranks highest and its National Register listings lowest.
A−
HistoryA character grade: shown, never part of Dexter’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 Dexter’s 15.7 sits near the middle of its state (51% of Maine towns have fewer) while its 6 historic buildings outnumber those of 72% 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 (±8.1 points). Two sources give 1801.

Dexter was settled beginning in 1801 by Ebenezer Small, David Smith, and others from New Hampshire, and was originally called Elkinstown. When incorporated as a town in 1816, it named itself after Judge Samuel Dexter, who was then running for governor of Massachusetts (of which Maine was still a part). The town of Brooks in nearby Waldo County was incorporated the same year and named for the opposing candidate, John Brooks. Brooks won the election. The town of Dexter, however, achieved the greater prosperity.
