The population was 990 at the 2020 census, which ranks it the least-populated township in the county.

This is a significant decrease from 3,326 at the 2010 census, which was due to the village of Jonesville incorporating as an autonomous city in 2014.

25.1% of all households were made up of individuals, and 11.2% had someone living alone who was 65 years of age or older.

The township is served by two separate public school districts.

The northern portion of the township is served by Jonesville Community Schools, while the southern section near Hillsdale is served by Hillsdale Community Schools.
