On its age, its old homes and the National Register, Odessa Township is more historic than 63% of U.S. towns, #255 of 701 in Michigan. Its share of homes from before 1940 holds the grade up; its National Register listings pull it down.

HistoryA character grade: shown, never part of Odessa Township’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 Odessa Township’s 0.0 sits below most of its state (32% of Michigan towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.
How sure. Graded on two of the three inputs, so a change in either one moves the letter more than it would with three. The pre-1940 share is a Census survey estimate (±8.7 points).
