More historic than 25% of U.S. towns. What drives it
Most of Hillman Township was built recently: 7% of its homes predate 1940 and the median home dates from 1975. Below: maps from 1955 on and the census since 1900.
The Hillman Township post office opened in 1882, the earliest record of the town by name.
More historic than 25% of U.S. towns, on its age, its old homes and the National Register.
On its age, its old homes and the National Register, Hillman Township is more historic than 25% of U.S. towns. Its share of homes from before 1940 holds the grade up; its National Register listings pull it down.
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 Hillman 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.
Founding year: the first post office (other dates in Quick answers). Homes: Census ACS 2020–24. National Register: National Park Service, May 2026 list; each listing counted once (boundary changes and added documentation belong to their listing), and a historic district counts its contributing buildings.
