Consolidated city-county

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. A consolidated city-county differs from an independent city in that the city and county both nominally exist, although they have a consolidated government, whereas in an independent city, the county does not even nominally exist.

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 Louisiana, consolidated-city counties are called city-parish consolidated governments.[1]


According to information compiled by former Albuquerque mayor David Rusk, 105 referenda were held in the United States between 1902 and 2010 to consider proposals to consolidate cities and counties. Only 27 of these proposals were approved by voters.[2]

Wyandotte County, Kansas, uses the term "unified government" to refer to its consolidation with Kansas City, Kansas, and most of the towns within the county boundaries in which some cities and towns remain separate jurisdictions within the county. Individual sections of a metropolitan or regional municipality may retain some autonomous jurisdiction apart from the citywide government.

Often, in place of another level of government, local governments form councils of governments – essentially governmental organizations which are not empowered with any law-making or law enforcement powers. This is the case in the Atlanta metropolitan area, where the Atlanta Regional Commission (ARC) studies and makes recommendations on the impact of all major construction and development projects on the region, but generally cannot stop them. The Georgia Regional Transportation Authority (GRTA) is a true government agency of the state of Georgia, and does control some state transportation monies to the cities and counties, but otherwise has very little authority beyond this small power of the purse.

The case of New York City is unique, in that the city consists of five boroughs, each of which is co-extensive with a county. Each borough, being coterminous with a county, has its own district attorney; however, county-level government is essentially non-existent as all executive and legislative power is exercised by the city government throughout the five boroughs. The city, as currently constituted, was created in 1898 when the city of New York (then comprising what would become the boroughs of Manhattan and The Bronx) annexed Kings County, Queens County, and Richmond County as the boroughs of Brooklyn, Queens, and Staten Island, respectively.

Similar arrangements also exist in other countries. England has six "metropolitan counties" created in 1974: Greater Manchester, Merseyside, South Yorkshire, Tyne and Wear, West Midlands, and West Yorkshire. From 1986, these metropolitan counties do not have county councils but rather joint boards for certain functions. Modern unitary authorities are similar, and are known as county boroughs in Wales. 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. 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). 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. Similarly, the City of Tokyo merged with the prefecture to form Tokyo metropolis in 1943.


In nine consolidated city-county governments in the United States, the formerly independent incorporated places maintain some governmental powers. 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. A part of the consolidated government is called the "balance", which the Census Bureau defines as "the consolidated city minus the semi-independent incorporated places located within the consolidated city".[3]

These consolidated cities are:[3]

Merged with some independent municipalities[]

Five cities in the Hampton Roads region of Virginia were formed by the consolidation of a city with a county: Chesapeake, Hampton, Newport News, Suffolk, and Virginia Beach (from Norfolk, Elizabeth City, Warwick, Nansemond, and Princess Anne counties, respectively). However, in each case an independent city was created and as such they are not consolidated city-counties. Instead, the Code of Virginia uses the term "consolidated city."[23] Similarly, Carson City was consolidated with Ormsby County, Nevada in 1969, but the county was simultaneously dissolved. The city is now a municipality independent of any county.
