What drives Baldwin’s History grade
On its age, its old homes and the National Register, Baldwin is more historic than 77% of U.S. towns. All 3 inputs are above most U.S. towns; its age ranks highest and its share of homes from before 1940 lowest.
A−
HistoryA character grade: shown, never part of Baldwin’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 Baldwin’s 25.6 sits near the middle of its state (64% of Maine towns have fewer) while its 3 historic buildings outnumber those of 65% 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 (±4.8 points). The founding year is the first post office, not a stated founding date.

What stands out about Baldwin’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
First called Flintstown Plantation, it was granted in 1774 by the Massachusetts General Court to survivors of the Concord, Massachusetts, company commanded by Captain John Flint. It replaced a grant of about 1735 which gave them Township No. 3, because when state borders were adjusted in 1741, the town turned out to be in New Hampshire—present-day Walpole. On June 23, 1802, Flintstown was incorporated as Baldwin, named for Colonel Loammi Baldwin, for whom the Baldwin apple was named. Sebago was set off and incorporated in 1826.
