What drives Caro’s History grade
On its age, its old homes and the National Register, Caro is more historic than 76% of U.S. towns, #162 of 701 in Michigan. Its share of homes from before 1940 holds the grade up; its age pulls it down.
A−
HistoryA character grade: shown, never part of Caro’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 Caro’s 11.7 sits above most of its state (84% of Michigan towns have fewer) while its 5 historic buildings outnumber those of 70% 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 (±6.7 points). The founding year is the first post office, not a stated founding date; Wikidata’s 1871 falls in the same era, so the grade doesn’t depend on which one is used.
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.

Every building
Caro, building by building, 1884–1909
Fire insurance maps drew every building, what it was made of and what it was used for, so insurers could price the risk of fire. Pick a year, then a sheet.
Caro was founded on the ridge just above the site of the Chippewa Village that early on stood at the Oxbow in the Cass River that was known by Native Americans as "Pe-See-Kop-To-Qua-Yone." It is now the site of the Caro Dam in Section 10, Indianfields Township, Tuscola County. Caro would be built and organized on Section 3. On Section 10, at the gate of the Chippewa Village, the logging camp that started the "boom" in logging Cass River was established by Curtis Emerson in 1848. Paschel Richardson of Tuscola Village purchased land for logging on the future site of Caro or Section 3, Indianfields Township, also in 1848. The Johnson brothers, Daniel and Soloman, began to build the City of Zilwaukee, Michigan, from Cass River Pine timber that they logged from the land at the future site of Caro and that they bought in 1849. This was how the events would align.
