County (United States) in the context of "Nassau County, New York"

Special districts (also known as special service districts, special district governments, or limited purpose entities) are independent, special-purpose governmental units that exist separately from local governments such as county, municipal, and township governments, with substantial administrative and fiscal independence. They are formed to perform a single function or a set of related functions. The term special district governments as defined by the U.S. Census Bureau excludes school districts. In 2017, the U.S. had more than 51,296 special district governments.

In the United States, a state is a constituent political entity, of which there are 50. Bound together in a political union, each state holds governmental jurisdiction over a separate and defined geographic territory where it shares its sovereignty with the federal government. Due to this shared sovereignty, Americans are citizens both of the federal republic and of the state in which they reside. State citizenship and residency are flexible, and no government approval is required to move between states, except for persons restricted by certain types of court orders, such as paroled convicts and children of divorced spouses who share child custody.

State governments in the U.S. are allocated power by the people of each respective state through their individual state constitutions. All are grounded in republican principles (this being required by the federal constitution), and each provides for a government, consisting of three branches, each with separate and independent powers: executive, legislative, and judicial. States are divided into counties or county-equivalents, which may be assigned some local governmental authority but are not sovereign. County or county-equivalent structure varies widely by state, and states also create other local governments.

A minor civil division (MCD) is a term used by the United States Census Bureau for primary governmental and/or administrative divisions of a county or county-equivalent, typically a municipal government such as a city, town, or civil township. MCDs are used for statistical purposes by the Census Bureau, and do not necessarily represent the primary form of local government. They range from non-governing geographical survey areas to municipalities with weak or strong powers of self-government. Some states with large unincorporated areas give substantial powers to counties; others have smaller or larger incorporated entities with governmental powers that are smaller than the MCD level chosen by the Census.

As of 2010, MCDs exist in 29 states, the District of Columbia, and Puerto Rico. In all other states where state-defined entities are not used for census purposes (mostly in the South and the West), the Census Bureau designates Census County Divisions (CCDs). For several decennial censuses prior to the 2010 census, 28 states used MCDs, but in 2008, Tennessee changed from CCDs to MCDs, bringing the total number of MCD states to 29.

In the United States, a district attorney (DA), county attorney, county prosecutor, state attorney, state's attorney, prosecuting attorney, commonwealth's attorney, or solicitor is the chief prosecutor or chief law enforcement officer representing a U.S. state in a local government area, typically a county or a group of counties. The exact scope of the office varies by state. Generally, the prosecutor is said to represent the people of the jurisdiction in the state's courts, typically in criminal matters, against defendants. District attorneys are elected in almost all states, and the role is generally partisan. This is unlike similar roles in other common law jurisdictions, where chief prosecutors are appointed based on merit and expected to be politically independent.

The prosecution is the legal party responsible for presenting the case against an individual suspected of breaking the state's criminal law, initiating and directing further criminal investigations, guiding and recommending the sentencing of offenders, and are the only attorneys allowed to participate in grand jury proceedings. The prosecutors decide what criminal charges to bring, and when and where a person will answer to those charges. In carrying out their duties, prosecutors have the authority to investigate persons, grant immunity to witnesses and accused criminals, and plea bargain with defendants.

Arlington County, or simply Arlington, is a county in the U.S. state of Virginia. The county, which is located in the Washington metropolitan area and the broader Northern Virginia region, is positioned directly across from Washington, D.C., the national capital, on the southwestern bank of the Potomac River. The smallest self-governing county in the United States by area, Arlington County has both suburban and urbanized districts. Its urbanized districts are located in proximity to several Washington Metro stations and lines. Its seat of government is located in the Court House neighborhood, which hosts many of its administrative offices and county courthouse.

Originally part of the Nacotchtank tribe's territory prior to the establishment of the Colony of Virginia in 1606, English colonists began settling in Arlington by the 1670s; the area was eventually designated as part of Fairfax County in 1742. The colonial-era economy was mostly based in tobacco agriculture operated with enslaved labor and indentured servants on large plantations. Following the end of the Revolutionary War, Arlington's planters and yeoman farmers transitioned to other crops. Virginia ceded present-day Arlington to help form the District of Columbia, and from 1801 the area was known as Alexandria County; it was eventually retroceded back to Virginia in 1847 as a result of pressure from Alexandria, which was the county's primary commercial center.

There are 62 counties in the U.S. state of New York.

The first 12 counties were created in 1683 soon after the British took over the Dutch colony of New Amsterdam; two of these counties were later abolished, their land going to Massachusetts. These counties were carried over after independence in 1783, but most of the counties were created by the state in the 19th century. The newest county is the Bronx, created in 1914 from the portions of New York County that had been annexed from Westchester County in the late 19th century. New York's counties are named for various Native American words; British provinces, counties, cities, and royalty; early American statesmen and military personnel; and New York State politicians.

In the United States, a metropolitan statistical area (MSA) is a geographical region with a relatively high population density at its core and close economic ties throughout the region. Such regions are not legally incorporated as a city or town would be and are not legal administrative divisions like counties or separate entities such as states. As a result, sometimes the precise definition of a given metropolitan area will vary between sources. The statistical criteria for a standard metropolitan area were defined in 1949 and redefined as a metropolitan statistical area in 1983.

Due to suburbanization, the typical metropolitan area is polycentric rather than being centered around a large historic core city such as New York City or Chicago. Some metropolitan areas include more than one large historic core city; examples include the Dallas–Fort Worth metroplex, Virginia Beach–Norfolk–Newport News (Hampton Roads), Riverside–San Bernardino (Inland Empire), and Minneapolis–Saint Paul (Twin Cities).
