New York City is the most populous city in the United States, and the center of the New York metropolitan area, which is among the most populous urban areas in the world. New York exerts a powerful influence over worldwide commerce, finance, culture, fashion and entertainment. As host of the United Nations headquarters, it is also an important center for international affairs.
Located on a large natural harbor on the Atlantic coast of the Northeastern United States, the city consists of five boroughs: The Bronx, Brooklyn, Manhattan, Queens, and Staten Island.
New York is notable among American cities for its high use of mass transit, most of which runs 24 hours per day, and for the overall density and diversity of its population. The city is sometimes referred to as "The City that Never Sleeps", while other nicknames include Gotham and the Big Apple.
Many neighborhoods and landmarks in the city have become world-famous. The Statue of Liberty greeted millions of immigrants as they came to America in the late 19th and early 20th centuries. Wall Street, in Lower Manhattan, has been a dominant global financial center since World War II and is home to the New York Stock Exchange. The city has been home to several of the tallest buildings in the world, including the Empire State Building and the twin towers of the former World Trade Center.
New York is the birthplace of many cultural movements, including the Harlem Renaissance in literature and visual art, abstract expressionism (also known as the New York School) in painting, and hip hop, punk, salsa, disco and Tin Pan Alley in music. It is the home of Broadway theater.
Since 2005 the city has had the lowest crime rate among the 25 largest U.S. cities, having become significantly safer after a spike in crime in the 1980s and early 1990s from the crack epidemic that affected many neighborhoods. By 2002, New York City had about the same crime rate as Provo, Utah and was ranked 197th in crime among the 216 U.S. cities with populations greater than 100,000. Violent crime in New York City decreased more than 75% from 1993 to 2005 and continued decreasing during periods when the nation as a whole saw increases. In 2005 the homicide rate was at its lowest level since 1966, and in 2007 the city recorded fewer than 500 homicides for the first time ever since crime statistics were first published in 1963.
Sociologists and criminologists have not reached consensus on what explains the dramatic decrease in the city's crime rate. Some attribute the phenomenon to new tactics used by the New York City Police Department, including its use of CompStat and the broken windows theory. Others cite the end of the crack epidemic and demographic changes.
Organized crime has long been associated with New York City, beginning with the Forty Thieves and the Roach Guards in the Five Points in the 1820s. The 20th century saw a rise in the Mafia dominated by the Five Families. Gangs including the Black Spades also grew in the late 20th century. As early as 1850, New York City recorded more than 200 gang wars fought largely by youth gangs. The most prominent gangs in New York City today are the Bloods, Crips, Latin Kings, and MS-13.
