In the United States, a county is an administrative or political subdivision of a state that consists of a geographic region with specific boundaries and usually some level of governmental authority.The term "county" is used in 48 U.S. states, while Louisiana and Alaska have functionally equivalent subdivisions called parishes and boroughs, respectively.
The specific governmental powers of counties vary widely between the states. Counties have significant functions in all states except Rhode Island and Connecticut, where county governments have been abolished but the entities remain for administrative or statistical purposes. Massachusetts has removed most government functions from eight of its 14 counties. County populations also vary widely: in 2017 according to the Census Bureau more than half the U.S. population is concentrated in just 143 of the thousands of counties, or just 4.6% of all counties; the five largest counties ordered by population are Los Angeles County, California; Cook County, Illinois; Harris County, Texas; Maricopa County, Arizona; and San Diego County, California.
The number of counties per state ranges from the three counties of Delaware to the 254 counties of Texas. Most counties have subdivisions which may include townships, municipalities and unincorporated areas. Others have no further divisions, or may serve as a consolidated city-county where a city and a county have been merged into a unified jurisdiction. Some municipalities are in multiple counties; New York City is uniquely partitioned into five counties, referred to at the city government level as boroughs. Conversely, the independent cities of the states of Virginia, Maryland, Missouri, and Nevada are municipalities that do not legally belong to any county, but may still function as if they were consolidated city-counties.
The United States Census Bureau uses the term "county equivalent" to describe places that are comparable to counties, but called by different names. Louisiana parishes, the organized boroughs of Alaska, independent cities, and the District of Columbia are equivalent to counties for administrative purposes. Alaska's Unorganized Borough, a 323,440-square-mile (837,700 km2) area that has no county equivalent government, is further divided into 11 census areas that are statistically equivalent to counties.
Territories of the United States do not have counties; instead, the United States Census Bureau also divides them into county equivalents. The U.S. Census Bureau counts American Samoa's districts and atolls as county-equivalents.American Samoa locally has places called "counties", but these entities are considered to be "minor civil divisions" (not true counties) by the U.S. Census Bureau.
As of 2020 [update] , there are currently 3,143 counties and county-equivalents in the 50 states and the District of Columbia. If the 100 county equivalents in the U.S. territories are counted, then the total is 3,243 counties and county-equivalents in the United States. The county with the largest population, Los Angeles County (10,039,107), and the county with the largest land area, San Bernardino County, border each other in Southern California (however, eleven boroughs in Alaska are larger in area than San Bernardino).
The origin of the American counties are in the counties of England. English (after 1707 British) colonists brought to their colonies in North America a political subdivision that they already used in the British metropolis: the counties. Counties were among the earliest units of local government established in the Thirteen Colonies that would become the United States. Virginia created the first counties in order to ease the administrative workload in Jamestown. The House of Burgesses divided the colony first into four "incorporations" in 1617 and finally into eight shires (or counties) in 1634: James City, Henrico, Charles City, Charles River, Warrosquyoake, Accomac, Elizabeth City, and Warwick River.America's oldest intact county court records can be found at Eastville, Virginia, in Northampton (originally Accomac) County, dating to 1632. Maryland established its first county, St. Mary's, in 1637, and Massachusetts followed in 1643. Pennsylvania and New York delegated significant power and responsibility from the colony government to county governments and thereby established a pattern for most of the United States, although counties remained relatively weak in New England.
When independence came, "the framers of the Constitution did not provide for local governments. Rather, they left the matter to the states. Subsequently, early state constitutions generally conceptualized county government as an arm of the state." In the twentieth century, the role of local governments strengthened and counties began providing more services, acquiring home rule and county commissions to pass local ordinances pertaining to their unincorporated areas.
In some states, these powers are partly or mostly devolved to the counties' smaller divisions usually called townships, though in New York, New England and Wisconsin they are called "towns". The county may or may not be able to override its townships on certain matters, depending on state law.
The newest county in the United States is the city and county of Broomfield, Colorado, established in 2001 as a consolidated city-county, previously part of four counties.The newest county-equivalents are the Alaskan boroughs of Skagway established in 2007, Wrangell established in 2008, and Petersburg established in 2013.
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. There are 40 consolidated city-counties in the U.S.,including Augusta, Georgia; Denver, Colorado; Honolulu, Hawaii; Indianapolis, Indiana; Jacksonville, Florida; Louisville, Kentucky; Lexington, Kentucky; Kansas City, Kansas; Nashville, Tennessee; New Orleans, Louisiana; Philadelphia, Pennsylvania; and San Francisco, California.
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.
The term county equivalents is used by the United States Census Bureau to describe divisions that are comparable to counties but called by different names:
Consolidated city-counties are not designated county-equivalents for administrative purposes; since both the city and the county at least nominally exist, they are properly classified as counties in their own right. The same is true of the boroughs of New York City, each of which is coextensive with a county of New York State.
There are technically no counties in U.S. territories. American Samoa has its own counties, but the U.S. Census Bureau does not count them as counties (instead, the U.S. Census Bureau counts American Samoa's three districts and two atolls as county equivalents).American Samoa's counties are treated as minor civil divisions. Most territories are directly divided into municipalities or similar units, which are treated as equivalent of counties for statistical purposes:
The U.S. Census Bureau counts all of Guam as one county-equivalent (with the FIPS code 66010),while the USGS counts Guam's election districts (villages) as county-equivalents. The U.S. Census Bureau counts the 3 main islands in the U.S. Virgin Islands as county-equivalents, while the USGS counts the districts of the U.S. Virgin Islands (of which there are 2) as county-equivalents.
Common sources of county names are names of people, geographic features, places in other states or countries, and animals. Quite a few counties bear names of Native American, French, or Spanish origin.
Counties are most often named for people, often political figures or early settlers, with over 2,100 of the 3,144 total so named. The most common county name, with 31, is Washington County, for America's first president, George Washington. Up until 1871, there was a Washington County within the District of Columbia, but it was dissolved by the District of Columbia Organic Act. Jefferson County, for Thomas Jefferson, is next with 26. The most recent president to have a county named for him was Warren G. Harding, reflecting the slowing rate of county creation since New Mexico and Arizona became states in 1912. The most common names for counties not named after a president are Franklin (25), Clay (18), and Montgomery (18).
After people, the next most common source of county names are geographic features and locations, with some counties even being named after counties in other states, or for places in countries such as the United Kingdom. The most common geographic county name is Lake. Words from Native American languages, as well as the names of Native American leaders and tribes, lend their names to many counties.Quite a few counties bear names of French or Spanish origin, such as Marquette County being named after French missionary Father Jacques Marquette.
The county's equivalent in the state of Louisiana, the parish (Fr. paroisse civile and Sp. parroquia) took its name during the state's French and Spanish colonial periods. Before the Louisiana Purchase and granting of statehood, government was often administered in towns where major church parishes were located. Of the original 19 civil parishes of Louisiana that date from statehood in 1807, nine were named after the Roman Catholic parishes from which they were governed.
The structure and powers of a county government may be defined by the general law of the state or by a charter specific to that county. States may allow only general-law counties, only charter counties, or both. Generally, general-law local governments have less autonomy than chartered local governments.
Counties are usually governed by an elected body, variously called the county commission, board of supervisors, commissioners' court, county council, board of chosen freeholders, county court, or county Legislature. In cases in which a consolidated city-county or independent city exists, a City Council usually governs city/county or city affairs. In some counties, day-to-day operations are overseen by an elected county executive or by a chief administrative officer or county administrator who reports to the board, the mayor, or both.
In many states, the board in charge of a county holds powers that transcend all three traditional branches of government. It has the legislative power to enact ordinances for the county; it has the executive power to oversee the executive operations of county government; and it has quasi-judicial power with regard to certain limited matters (such as hearing appeals from the planning commission if one exists).
In many states, several important officials are elected separately from the board of commissioners or supervisors and cannot be fired by the board. These positions may include county clerk, county treasurer, county surrogate, sheriff, and others.
District attorneys or state attorneys are usually state-level as opposed to county-level officials, but in many states, counties and state judicial districts have coterminous boundaries.
The site of a county's administration, and often the county courthouse, is generally called the county seat ("parish seat" in Louisiana, "borough seat" in Alaska, or "shire town" in several New England counties). The county seat usually resides in a municipality. However, some counties may have multiple seats or no seat. In some counties with no incorporated municipalities, a large settlement may serve as the county seat.
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 Connecticut and Rhode Island, counties are geographic entities, but not governmental jurisdictions. At the other extreme, Maryland counties and the county-equivalent City of Baltimore handle almost all services, including public education, although the state retains an active oversight authority with many of these services.
In most Midwestern and Northeastern states, counties are further subdivided into townships or towns, which sometimes exercise local powers or administration. Throughout the United States, counties may contain other independent, self-governing municipalities.
In New England, counties function at most as judicial court districts and sheriff's departments (presently, in Connecticut only as judicial court districts—and in Rhode Island, they have lost both those functions and most others but they are still used by the United States Census Bureau and some other federal governmental agency's for some federal functions ), and most of the governmental authority below the state level is in the hands of towns and cities. In several of Maine's sparsely populated counties, small towns rely on the county for law enforcement, and in New Hampshire 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.The regional councils' authority is limited compared with a county government—they have authority only over infrastructure and land use planning, distribution of state and federal funds for infrastructure projects, emergency preparedness, and limited law enforcement duties.
In the Mid-Atlantic and Midwest, counties typically provide, at a minimum, courts, public utilities, libraries, hospitals, public health services, parks, roads, law enforcement, and jails. There is usually a county registrar, recorder, or clerk (the exact title varies) who collects vital statistics, holds elections (sometimes in coordination with a separate elections office or commission), and prepares or processes certificates of births, deaths, marriages, and dissolutions (divorce decrees). The county recorder normally maintains the official record of all real estate transactions. Other key county officials include the coroner/medical examiner, treasurer, assessor, auditor, comptroller, and district attorney.
In most states, the county sheriff is the chief law enforcement officer in the county. However, except in major emergencies where clear chains of command are essential, the county sheriff normally does not directly control the police departments of city governments, but merely cooperates with them (e.g., under mutual aid 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. But long-term incarceration is rarely a county responsibility, execution of capital punishment is never a county responsibility, and the state's responses to prisoners' appeals are the responsibility of the state attorney general, who has to defend before the state appellate courts the prosecutions conducted by locally elected district attorneys in the name of the state. Furthermore, county-level trial court judges are officers of the judicial branch of the state government rather than county governments.
In many states, the county controls all unincorporated lands within its boundaries. In states with a township tier, unincorporated land is controlled by the townships. Residents of unincorporated land who are dissatisfied with county-level or township-level resource allocation decisions can attempt to vote to incorporate as a city, town, or village.
A few counties directly provide public transportation themselves, usually in the form of a simple bus system. However, in most counties, public transportation is provided by one of the following: a special district that is coterminous with the county (but exists separately from the county government), a multi-county regional transit authority, or a state agency.
In western and southern states, more populated counties provide many facilities, such as airports, convention centers, museums, recreation centers, beaches, harbors, zoos, clinics, 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, 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, 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 systems are organized and administered at the county level.
As of 2016 [update] , there were 3,007 counties, 64 parishes, 19 organized boroughs, 11 census areas, 41 independent cities, and the District of Columbia for a total of 3,143 counties and county-equivalents in the 50 states and District of Columbia. There are an additional 100 county equivalents in the territories of the United States. The average number of counties per state is 62, with a range from the three counties of Delaware to the 254 counties of Texas.
Southern and Midwestern states generally tend to have more counties than Western or Northeastern states, as many Northeastern states are not large enough in area to warrant a large number of counties, and many Western states were sparsely populated when counties were created. The five counties of Rhode Island, the eight counties of Connecticut, and eight of the 14 counties of Massachusetts no longer have functional county governments, but continue to exist as legal and census entities.

The average U.S. county population was over 100,000 in 2019. The most populous county is Los Angeles County, California, with 10,039,107 residents in 2019.This number is greater than the populations of 41 U.S. states. It also makes the population of Los Angeles County 17.4 times greater than that of the least populous state, Wyoming.
The second most populous county is Cook County, Illinois, with a population of 5,150,233.Cook County's population is larger than that of 28 individual U.S. states and the combined populations of the six smallest states.
The least populous county is Kalawao County, Hawaii, with 86 residents in 2019.Eight county-equivalents in the U.S. territories have no human population: Rose Atoll, Northern Islands Municipality, Baker Island, Howland Island, Jarvis Island, Johnston Atoll, Kingman Reef, and Navassa Island. The remaining three islands in the U.S. Minor Outlying Islands (Midway Atoll, Palmyra Atoll and Wake Island) have small non-permanent human populations. The county-equivalent with the smallest non-zero population counted in the census is Swains Island, American Samoa (17 people), although since 2008 this population has not been permanent either.
The most densely populated county or county-equivalent is New York County, New York (coextensive with the New York City Borough of Manhattan), with 72,033 persons per square mile (27,812/km2) in 2015. The Yukon–Koyukuk Census Area, Alaska, is both the most extensive and the least densely populated county or county-equivalent with 0.0380 persons per square mile (0.0147/km2) in 2015.
In the 50 states (plus District of Columbia), a total of 981 counties have a population over 50,000; 592 counties have a population over 100,000; 137 counties have a population over 500,000; 45 counties have a population over 1,000,000; and 14 counties have a population over 2,000,000. At the other extreme, 35 counties have a population under 1,000; 307 counties have a population under 5,000; 709 counties have a population under 10,000; and 1,492 counties have a population between 10,000 and 50,000.
At the 2000 U.S. Census, the median land area of U.S. counties was 622 sq mi (1,610 km2), which is two-thirds of the median land area of a ceremonial county of England, and a little more than a quarter of the median land area of a French département . Counties in the western United States typically have a much larger land area than those in the eastern United States. For example, the median land area of counties in Georgia is 343 sq mi (890 km2), whereas in Utah it is 2,427 sq mi (6,290 km2).
The most extensive county or county-equivalent is the Yukon–Koyukuk Census Area, Alaska, with a land area of 145,505 square miles (376,856 km2). All nine of the most extensive county-equivalents are in Alaska. The most extensive county is San Bernardino County, California, with a land area of 20,057 square miles (51,947 km2). The least extensive county is Kalawao County, Hawaii, with a land area of 11.991 square miles (31.058 km2). The least extensive county-equivalent in the 50 states is the independent City of Falls Church, Virginia, with a land area of 1.999 square miles (5.177 km2). If U.S. territories are included, the least extensive county-equivalent is Kingman Reef, with a land area of 0.01 square miles (0.03 km2).
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 municipalities in multiple counties. Dallas and Oklahoma City, for example, both contain portions of five 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 the city: Manhattan (New York County), The Bronx (Bronx County), Queens (Queens County), Brooklyn (Kings County), and Staten Island (Richmond County).
A county is a geographical region of a country used for administrative or other purposes in certain modern nations. The term is derived from the Old French conté or cunté denoting a jurisdiction under the sovereignty of a count (earl) or a viscount. Literal equivalents in other languages, derived from the equivalent of "count", are now seldom used officially, including comté, contea, contado, comtat, condado, Grafschaft, graafschap, and zhupa in Slavic languages; terms equivalent to English language administrative terms such as municipality, district, circuit and commune/community are now often instead used.
In the United States, an unorganized territory is a region of land under U.S. sovereignty that is not within the bounds of a U.S. state and that is without a government established by the United States Congress through an organic act. The term was historically applied either to a newly acquired region not yet constituted as an organized incorporated territory, or to a region previously part of an organized incorporated territory left "unorganized" after part of it had been organized and achieved the requirements for statehood. The U.S. currently exercises sovereignty over ten unorganized territories: American Samoa, Baker Island, Howland Island, Jarvis Island, Johnston Atoll, Kingman Reef, Midway Atoll, Navassa Island, Palmyra Atoll, and Wake Island.
A school district is a special-purpose district that operates local public primary and secondary schools in various nations.
In 48 of the 50 states of the United States, the county is used for the level of local government immediately below the state itself. Louisiana uses parishes, and Alaska uses boroughs. In several states in New England, some or all counties within states have no governments of their own; the counties continue to exist as legal entities, however, and are used by states for some administrative functions and by the United States Census bureau for statistical analysis. There are 3,242 counties and county equivalent administrative units in total, including the District of Columbia and 100 county-equivalents in the U.S. territories.
Political divisions of the United States are the various recognized governing entities that together form the United States – states, the District of Columbia, territories and Indian reservations.
Territories of the United States are sub-national administrative divisions overseen by the United States government. The various US territories differ from the US states and Native American tribes in that they are not sovereign entities. In contrast, each state has a sovereignty separate to that of the federal government and each federally-recognized Native American tribe possesses limited tribal sovereignty as a "dependent sovereign nation". Territories are classified by incorporation and whether they have an "organized" government through an organic act passed by the Congress. U.S. territories are under U.S. sovereignty and, consequently, may be treated as part of the United States proper in some ways and not others. Unincorporated territories in particular are not considered to be integral parts of the United States, and the Constitution of the United States applies only partially in those territories.
Local government in the United States refers to governmental jurisdictions below the level of the state. Most states and territories have at least two tiers of local government: counties and municipalities. In some states, counties are divided into townships. There are several different types of jurisdictions at the municipal level, including the city, town, borough, and village. The types and nature of these municipal entities vary from state to state. In addition to these general-purpose local governments, states may also create special-purpose local governments.
The Unorganized Borough is made up of the portions of the U.S. state of Alaska which are not contained in any of its 19 organized boroughs. While referred to as the "Unorganized Borough", it is not a borough itself, as it forgoes that level of government structure. It encompasses nearly half of Alaska's land area, 323,440 square miles (837,700 km2), an area larger than any other U.S. state, and larger than the land area of the smallest 16 states combined. As of the 2000 U.S. Census, it had a population of 81,803, which was 13% of the population of the state.
A borough in some U.S. states is a unit of local government or other administrative division below the level of the state. The term is currently used in six states:
American Samoa is administratively divided into three districts and two unorganized atolls. The districts are subdivided into 15 counties, which are composed of 76 villages.
In the United States, an independent city is a city that is not in the territory of any county or counties, with certain exceptions. Independent cities are classified by the United States Census Bureau as "county equivalents", and may also have similar governmental powers as a consolidated city-county. However in the case of a consolidated city-county, a city and a county were merged into a unified jurisdiction in which the county at least nominally exists to this day, whereas an independent city was legally separated from any county or merged with a county that simultaneously ceased to exist even in name.

This information is displayed in two tables. The first table ranks the cities, CBSAs, and PSAs separately by population. The second table displays the areas in hierarchical order by the most populous PSA, then most populous CBSA, and then most populous city.
There are no county seats in Connecticut. County government was abolished effective October 1, 1960; counties function only as geographical subdivisions.
Rhode Island has no county government. It is divided into 39 municipalities each having its own form of local government.
