Consolidated city-county

In United States local government, a consolidated city-county is a city and county that have a merged government, and is considered both a city and a county under the laws of the State. This is not to be confused with an independent city, which is a city that does not belong to any county in the state. This arrangement in the U.S. is frequently referred to as a metropolitan government or a metropolitan county.

A similar arrangement used to exist in the United Kingdom where it was known as a county borough; modern unitary authorities are similar, and are known as county boroughs in Wales.

Similar arrangements exist in other countries such as Landshut, Germany and Landshut County, Bavaria, Germany and Seoul, South Korea which is a Special City.

Wyandotte County, Kansas uses the term "unified government" to refer to its consolidation where a few city governments have been merged with the county government while other cities and towns retain a traditional relationship with the county.

Potentially consolidated governments

Many cities around the United States are considering merging their governments with the county that comprises them.
