Subdivisions

The first 12 were created immediately after the British took over the Dutch colony of New Amsterdam; two of these counties were later abolished, their land going to Massachusetts.[1] The newest is Bronx County, created in 1914 from the portions of New York City that had been annexed from Westchester County in the late 19th century and added to New York County.[2] 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.[3]

The county boundaries in New York state were last changed in 1964, when the Bronx gained South Brother Island from Queens.[4]

Authority

Excepting the five boroughs of New York City, New York counties are governed by New York County Law and have governments run by either a Board of Supervisors or a County Legislature, and either an elected County Executive or appointed county manager. Counties without charters are run by a Board of Supervisors, in which Town Supervisors from towns within the county also sit on the county Board of Supervisors. For counties with a charter, the executives generally have powers to veto acts of the county legislature. The legislatures have powers of setting policies, levying taxes and distributing funds.

Five boroughs of New York City

Five of New York's counties are each coextensive with New York City's five boroughs. They are New York County (Manhattan), Kings County (Brooklyn), Bronx County (The Bronx), Richmond County (Staten Island), and Queens County (Queens).

In contrast to other counties of New York, the powers of the five boroughs of New York City are very limited and in nearly all respects are governed by the city government.[5] Only a few officials are elected on a borough-wide basis, such as the five borough presidents, district attorneys, and all county and state supreme court judges. There are no official county seats, but the locations of borough halls and courthouses bestow certain neighborhoods an informal designation as county seats within their boroughs:
