===Consolidated city-counties===
{{main|Consolidated city-county}}
A consolidated city-county is simultaneously a city, which is a [[municipality]] (municipal corporation), and a county, which is an [[administrative division]] of a state, having the powers and responsibilities of both types of entities. The [[City limits|city limit]] or jurisdiction is synonymous with the county line, as the two administrative entities become a non-dichotomous single entity. For this reason, a consolidated city-county is officially remarked as ''name of city – name of county'' (i.e., [[Augusta, Georgia|Augusta–Richmond County]] in Georgia). The same is true of the [[boroughs of New York City]], each of which is coextensive with a county of New York State. For those entities in which the city uses the same name as the county, ''city and county of name'' may be used (i.e., [[Denver|City and County of Denver]] in Colorado).

Similarly, some of [[Alaska]]'s boroughs have merged with their principal cities, creating unified city-boroughs. Some such consolidations and mergers have created cities that rank among the geographically largest cities in the world, though often with population densities far below those of most urban areas.

There are 40 consolidated city-counties in the U.S.,<ref name=NACO/> including Augusta–Richmond County; the City and County of Denver, Colorado; the [[Honolulu|City and County of Honolulu, Hawaii]]; [[Indianapolis|Indianapolis–Marion County, Indiana]]; [[Jacksonville, Florida|Jacksonville–Duval County, Florida]]; [[Louisville, Kentucky|Louisville–Jefferson County, Kentucky]]; [[Lexington, Kentucky|Lexington–Fayette County, Kentucky]]; [[Kansas City, Kansas|Kansas City–Wyandotte County, Kansas]]; [[Nashville, Tennessee|Nashville–Davidson County, Tennessee]]; [[New Orleans|New Orleans–Orleans Parish, Louisiana]]; the [[Philadelphia|City and County of Philadelphia, Pennsylvania]]; [[San Francisco|City and County of San Francisco, California]]; and [[Lynchburg, Tennessee|Lynchburg-Moore County, Tennessee]]

A consolidated city-county may still contain independent municipalities maintaining some governmental powers that did not merge with the rest of the county. For example, the [[Government of Jacksonville|government of Jacksonville–Duval County, Florida]], still provides county-level services to the four independent municipalities within its borders: [[Atlantic Beach, Florida|Atlantic Beach]], [[Baldwin, Florida|Baldwin]], [[Jacksonville Beach, Florida|Jacksonville Beach]], and [[Neptune Beach, Florida|Neptune Beach]].
