HistoryA character grade: shown, never part of Sumpter 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 Sumpter 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 (±3.7 points).

Sumpter Township was designated Township 4 South in Range 8 East of Wayne County. The original survey was approved on November 5, 1819. Federal land in Sumpter Township began to be sold to individuals by the 1830s, with one land patent to Arthur Fuller on April 4, 1833. Sumpter Township has a brief history on their web page.
Sumpter Township, including Township 4 South, of Range 8 East, was taken from Huron township and erected into a separate township on April 6, 1840, under the name of West Huron. Subsequently the name was changed to that of Sumter in honor of General Thomas Sumter, Revolutionary war hero, but the engrossing clerk inserted a "p" in the name, which has since remained Sumpter.
