There are 64 counties in Colorado. The cities and counties of Broomfield and Denver are consolidated city-county governments. They are classified as municipal governments, rather than as county governments, because they operate primarily as cities. In each of the remaining 62 counties, the governing body is the board of county commissioners.
There are 209 county subdivisions in Colorado. They are all census county divisions (CCDs), which are delineated for statistical purposes, have no legal function, and are not governmental units. CCDs were first established in Colorado for the 1960 census. Prior to 1960, the minor civil divisions used in the census were election precincts.
