A
HistoryA character grade: shown, never part of Hart’s overall grade.
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 Hart’s 192 sits above most of its state (96% of Michigan towns have fewer) while its 37 historic buildings outnumber those of 83% 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 (±6.1 points). Two sources give 1856.
