What drives Plainwell’s History grade

On its age, its old homes and the National Register, Plainwell is more historic than 95% of U.S. towns, #33 of 701 in Michigan. All 3 inputs are above most U.S. towns; its National Register listings ranks highest and its age lowest.

Few Michigan towns list much on the Register (a typical Michigan town has 0.0 per 10,000 residents, the U.S. 2.4), so Plainwell’s 494 sits above most of its state (98% of Michigan towns have fewer) while its 186 historic buildings outnumber those of 93% 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 (±9.4 points). The founding year is the first post office, not a stated founding date.

The story

How Plainwell came to be

From Wikipedia’s history of Plainwell.

Read it all →

This part of Michigan was settled in the 1830s, after the removal of native people. Allegan County was organized in 1835, and the Plainwell area was settled soon after. It was on a stagecoach route from Kalamazoo to Grand Rapids, and later the Grand Rapids and Indiana Railroad was constructed along the same route. After the advent of the automobile, U.S. Route 131 was created and run through the town. In the 1960s, an improved 4-lane US-131 was built west of town to connect Kalamazoo and Grand Rapids, with an interchange on M-89 between Plainwell and Otsego. This allowed the town to become a kind of "bedroom community" for Kalamazoo or the southern part of Grand Rapids.
