In United States local government, a consolidated city–county is a city and county that have been merged into one unified jurisdiction. As such it is simultaneously a city, which is a municipal corporation, and a county, which is an administrative division of a state. It has the powers and responsibilities of both types of entities.
A consolidated city-county is different from an independent city, although the latter may result from consolidation of a city and a county and may also have the same powers as a consolidated city-county. An independent city is a city not deemed by its state to be located within the boundary of any county, and recognized by its state as a legal territorial entity separate from surrounding or adjoining counties. Not considering Hawaii, which has no independent cities, the Midwest and Upper South have the highest concentration of large consolidated city–county governments in the United States, including Indianapolis, Indiana; Nashville, Tennessee; Jacksonville, Florida; Louisville, Kentucky; Kansas City, Kansas; Lexington, Kentucky; and Denver, Colorado.
