The term county equivalents includes three additional types of administrative divisions whose organization differs from that of most counties:
Alaska areas: Most of the land area of Alaska is not contained within any of Alaska's 19 organized boroughs and one unorganized borough. This vast area, larger than France and Germany combined, is officially referred to by the Alaska state government as the Unorganized Borough, and, outside of other incorporated borough limits, has no independent "county" government, although several incorporated city governments exist within its boundaries; the majority of it is governed and run by the State of Alaska as an extension of state government.
Independent cities: These are cities that legally belong to no county. They differ from consolidated city-counties—where a city and county have been merged into one unified jurisdiction. As of 2004, there are 42 such cities in the United States, including Baltimore, Maryland; Carson City, Nevada; St. Louis, Missouri; and all 39 cities in Virginia, where any municipality incorporated as a city (in contrast to town) is by law severed from any county that might otherwise have contained it.
