What drives Hillsdale’s History grade

On its age, its old homes and the National Register, Hillsdale is more historic than 97% of U.S. towns, #17 of 701 in Michigan. All 3 inputs are above most U.S. towns; its share of homes from before 1940 ranks highest and its age lowest.

A+
HistoryA character grade: shown, never part of Hillsdale’s overall grade.
All U.S. towns we grade (21,289)Ahead of 97%
NewerOlder
Michigan towns of 2,500+ (701)Ahead of 98%

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 Hillsdale’s 120 sits above most of its state (95% of Michigan towns have fewer) while its 96 historic buildings outnumber those of 89% of U.S. towns.

How sure. Graded on any two of the three inputs instead, the letter would range from A to A+. The pre-1940 share is a Census survey estimate (±6.1 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. 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.

The story

How Hillsdale came to be

From Wikipedia’s history of Hillsdale.

Read it all →

This area is located in the rolling, fertile hills of South Central Michigan, bordering Indiana and Ohio, according to the boundaries set up under United States settlement. It was long occupied by the Potowatomi, an Algonquian-speaking people who were part of a long-term alliance, called the Council of Three Fires, with the Ojibwe and Odawa (Ottawa). A Potowatomi band of about 150 people, led by the chief known as Baw Beese, had a base camp near the large lake in the area.
