The type of government may range from inoperative, to weak governmental authority, to incorporated municipalities. Since MCDs appear in a different category than incorporated places, this has caused some confusion in states where the MCDs have strong governments, such as in Michigan, the New England states, New Jersey, New York, and Pennsylvania.
In states that do not have MCDs, the Census Bureau designates Census County Divisions (CCDs). In states that use MCDs, when any portion of the state is not covered by an MCD, the Census Bureau creates additional entities as unorganized territories, that it treats as equivalent to MCDs for statistical purposes.
