Minor civil division
Minor civil division (MCD) is the official term for the primary governmental or
administrative division of a
county in many States of the
United States.
Minor civil divisions include entities such as towns,
townships, and
districts.
MCDs exist in 28 States, the District of Columbia, Puerto Rico, and Island areas, such as American Samoa.
They are often nonfunctioning administrative units as they are not represented by elected officials in charge of legal duties.
