What drives Iron River’s History grade
On its age, its old homes and the National Register, Iron River is more historic than 84% of U.S. towns, #107 of 701 in Michigan. Its National Register listings hold the grade up; its age pulls it down.
A−
HistoryA character grade: shown, never part of Iron River’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 Iron River’s 243 sits above most of its state (97% of Michigan towns have fewer) while its 73 historic buildings outnumber those of 87% 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 (±7.4 points). The founding year is the first post office, not a stated founding date.
Founding year: the first post office (other dates in Quick answers). Homes: Census ACS 2020–24.

Originally settled in 1882 under the name 'Nanaimo', named after the Nanaimo iron mine, owned by the Mineral Hills Iron Company. In 1878, two brothers, Donald and Alexander MacKinnon acquired the site, and a village was platted and registered in 1881. The new town was given a station on the Chicago and North Western Railway and renamed 'Iron River' after the nearby Iron River. The settlement was incorporated as a village within Iron River Township in 1885, and as a city in 1926.
On November 2, 1999, the voters of the cities of Iron River and Stambaugh and the village of Mineral Hills approved consolidation into a new city, which continued the name Iron River. The consolidation became effective July 1, 2000.
