The following listing of the Minor Civil Divisions (also known as "County Subdivisions") included in each Congressional District of which the so-called DIVIDED COUNTIES are a part contains references to the Townships and the Cities only. There are two types of Municipality in Michigan: the City and the Village- but, while the City is administratively and governmentally separate from any Township, the Village remains a part of its Township and, thus, is itself a further subdivision of the Township; therefore, Villages- unlike Cities and Townships- do not constitute Minor Civil Divisions/County Subdivisions of the first order in the State of Michigan and, thus, no Villages are noted in this listing:
