HistoryA character grade: shown, never part of Harrison’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 Harrison’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 any two of the three inputs instead, the letter would range from C to C+. The pre-1940 share is a Census survey estimate (±4.4 points). Two sources give 1877.

Harrison was first designated as the new centralized location of the county seat of Clare County in 1877. It would become a replacement for Farwell, which was the first county seat when Clare County was formally organized in 1871. The Flint and Pere Marquette Railroad platted the village in 1879 and set aside property for a new county government after the previous courthouse in Farwell burned down. The Harrison post office opened on January 27, 1880 and was named after former president William Henry Harrison. The new community incorporated as a village in 1885 and later as a city in 1891.
