County variations


Consolidated city-counties

of a state, having the powers and responsibilities of both types of entities. The 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–Richmond County in Georgia). The same is true of the
boroughs of New York City The boroughs of New York City are the five major governmental districts that comprise New York City. They are the Bronx, Brooklyn, Manhattan, Queens, and Staten Island. Each borough is coextensive with a respective Administrative divisions of ...

'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., including Augusta–Richmond County; the City and County of Denver, Colorado; the City and County of Honolulu, Hawaii; Indianapolis–Marion County, Indiana; Jacksonville–Duval County, Florida; Louisville–Jefferson County, Kentucky; Lexington–Fayette County, Kentucky; Kansas City–Wyandotte County, Kansas; Nashville–Davidson County, Tennessee; New Orleans–Orleans Parish, Louisiana; the City and County of Philadelphia, Pennsylvania; City and County of San Francisco, California; and 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–Duval County, Florida, still provides county-level services to the four independent municipalities within its borders: Atlantic Beach, Baldwin, Jacksonville Beach, and Neptune Beach.

Georgetown was abolished as a city by another act in 1895. * Connecticut councils of governments (beginning in 2024): County governments were abolished in Connecticut in 1960.

Names and etymologies

("parish seat" in Louisiana, "borough seat" in Alaska, or " shire town" in several New England counties). The county seat usually resides in a municipality.

Scope of power

The power of county governments varies widely from state to state, as does the relationship between counties and incorporated cities. The powers of counties arise from state law and vary widely. In

several social programs are administered at the state level. In Connecticut, Rhode Island, and parts of Massachusetts, counties are now only geographic designations, and they do not have any governmental powers. All government is either done at the state level or at the municipal level. In Connecticut and parts of Massachusetts, regional councils have been established to partially fill the void left behind by the abolished county governments.Unlike in Massachusetts, Connecticut's regional councils do not conform to the old county lines, but rather, they are composed of towns that share the same geographic area and have similar demographics. The regional councils' authority is limited compared with a county government—they have authority only over infrastructure and

pacts). Thus, the most common interaction between county and city law enforcement personnel is when city police officers deliver suspects to sheriff's deputies for detention or incarceration in the county jail. In most states, the state courts and local law enforcement are organized and implemented along county boundaries, but nearly all of the substantive and procedural law adjudicated in state trial courts originates from the state legislature and state appellate courts. In other words, most criminal defendants are prosecuted for violations of state law, not local ordinances, and if they, the district attorney, or police seek reforms to the criminal justice system, they will usually have to direct their efforts towards the state legislature rather than the county (which merely implements state law). A typical criminal defendant will be arraigned and subsequently indicted or held over for trial before a trial court in and for a particular county where the crime occurred, kept in the county jail (if he is not granted bail or cannot make bail), prosecuted by the county's district attorney, and tried before a jury selected from that county.

Broad scope

In Western United States, western and Southern United States, southern states, more populated counties provide many facilities, such as airports, convention centers, museums, Community centre, recreation centers, beaches, harbors, zoos, clinics, law library, law libraries, and public housing. They provide services such as child and family services, elder services, mental health services, welfare services, veterans assistance services, Animal control officer, animal control, probation supervision, historic preservation, food safety regulation, and environmental health services. They have many additional officials like public defenders, arts commissioners, human rights commissioners, and planning commissioners. There may be a county fire department and a county police department – as distinguished from fire and police departments operated by individual cities, special districts, or the state government. For example, Gwinnett County, Georgia, and its county seat, the city of Lawrenceville, Georgia, Lawrenceville, each have their own police departments. (A separate county sheriff's department is responsible for security of the county courts and administration of the county jail.) In several southern states, Public school (government funded), public school systems are organized and administered at the county level.

Geographic relationships between cities and counties

In some states, a municipality may be in only one county and may not annex territory in adjacent counties, but in the majority of states, the state constitution or state law allows municipalities to extend across county boundaries. At least 32 states include List of U.S. cities in multiple counties, municipalities in multiple counties. Dallas, for example, contains portions of five counties, while numerous other cities comprise portions of four counties. New York City is an unusual case because it encompasses multiple entire counties in one city. Each of those counties is coextensive with one of the five Boroughs of New York City, boroughs of the city: Manhattan (New York County), The Bronx (Bronx County), Queens (Queens County), Brooklyn (Kings County), and Staten Island (Richmond County).
