Consolidated city-county
Encyclopedia
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. 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.
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 borough
s in Wales
. In Scotland, Aberdeen
, Dundee
, Edinburgh
and Glasgow
are functionally "independent cities", though the term is not used.
Similar arrangements exist in other countries such as Germany
, where Berlin
, Bremen
, and Hamburg
are both cities and states. 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.
According to information compiled by former Albuquerque mayor David Rusk, 105 referendum
s 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.
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 city-wide government.
Often, in place of another level of government, municipalities form coalition
s – 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. The boroughs retain some individual functions within the city government, but the counties are essentially merely administrative divisions. The city as currently constituted was created in 1898 by the consolidation of the independent cities of New York (i.e. Manhattan
) and Brooklyn
with Queens
and Richmond (Staten Island
) counties and a part of Westchester County which became The Bronx
.
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".
These consolidated cities are:
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." 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.
