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 Clarence 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.
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 (±8.5 points). The founding year is the first post office, not a stated founding date.

Like the rest of Calhoun County, Clarence Township was populated by Potawatomi people before the coming of Euro-Americans. The first Euro-American settler came to the township in 1836. It was not until 1845 that a Euro-American settled at Duck Lake. This was Jacob Nichols, who still had Potawatomi neighbors as his only close neighbors for several years after this.
The township was organized in 1838. The first school in the township was established the following year.
