Consolidating local government services
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; and Lexington, Kentucky.
Currently, the largest consolidated city-county in the United States by population is Philadelphia, Pennsylvania, while the largest by land-area is Sitka, Alaska.
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.
The single square mile that comprises the City of London is only a tiny part of the London as a capital city, which takes up 607 square miles.
In the Canadian province of Ontario, there exist several single-tier municipalities which serve the same sort of functions as American consolidated city-counties.
One example of this is the City of Toronto, which was created in 1998 from the amalgamation of the central government and the six constituent municipalities of the Metropolitan Municipality of Toronto (a type of regional municipality) which was originally created in 1954.
In Germany, Berlin and Hamburg are both cities and states (the state of Bremen consists of the cities of Bremen and Bremerhaven).
Only 27 of these proposals were approved by voters.Nearly every larger city in Germany is a consolidated city-county, like Frankfurt, Stuttgart, Munich or Dresden; Austria, where the capital of Vienna is both a city and state; France, where the capital city of Paris has been coterminous with the département of Paris since 1968; and South Korea, where Seoul is a special city, while six other cities (Busan, Daegu, Daejeon, Gwangju, Incheon, and Ulsan) are metropolitan cities.Additionally, the Australian Capital Territory government in Australia performs all municipal functions of the city of Canberra, and thus functions as an integrated city-territory.In Scotland, Aberdeen, Dundee, Edinburgh and Glasgow are functionally "independent cities", though the term is not used.London is unique however, being a ceremonial county (officially known as Greater London) containing the ancient City of London and 32 London boroughs.
In these cities, which the United States Census Bureau calls "consolidated cities", statistics are recorded both for the entire consolidated government and for the component municipalities.
