Las Vegas, /lɑːs ˈveɪɡəs/ (locally, also pronounced as /lɑːs ˈvɛɡɨs/) officially the City of Las Vegas and often known as simply Vegas, is the most populous city in the state of Nevada and the county seat of Clark County. Las Vegas is an internationally renowned major resort city known primarily for gambling, shopping, fine dining and nightlife and is the leading financial and cultural center for Southern Nevada. The city bills itself as The Entertainment Capital of the World, and is famous for its mega casino–hotels and associated entertainment. A growing retirement and family city, Las Vegas is the 31st-most populous city in the United States, with a population at the 2010 census of 583,756. The 2010 population of the Las Vegas metropolitan area was 1,951,269. The city is one of the top three leading destinations in the United States for conventions, business and meetings. Today, Las Vegas is one of the top tourist destinations in the world.
Established in 1905, Las Vegas was incorporated as a city in 1911. At the close of the 20th century, Las Vegas was the most populous American city founded in that century (a distinction held by Chicago in the 19th century). The city's tolerance for various forms of adult entertainment earned it the title of Sin City, and has made Las Vegas a popular setting for films and television programs.
Las Vegas is commonly used to describe not just the city, but areas beyond the city limits - especially the resort areas on and near the Las Vegas Strip - and the Las Vegas Valley. The 4.2 mi (6.8 km) stretch of South Las Vegas Boulevard known as the Strip is in the unincorporated communities of Paradise, Winchester, and Enterprise (Clark County).
