Las Vegas, city, seat (1909) of Clark county, southeastern Nevada, U.S. The only major city in the American West to have been founded in the 20th century, Las Vegas grew from a tiny, desert-bound railroad service centre at the outset of the 20th century to the country’s fastest-growing metropolis at century’s end. This transformation—made possible by a combination of shrewd entrepreneurship, access to water, an extensive transportation network, and permissive state laws—has created the city now often known simply as “Vegas,” a place of vast casinos, elaborate hotels, and spectacular entertainment venues that attracts masses of visitors from throughout the world.
Las Vegas is Nevada’s economic centre and largest city. Its metropolitan area, with more than twice the number of people outside the city limits as within them, contains roughly three-fourths of the state’s population. Area 83 square miles (215 square km). Pop. (2010) 583,756; Las Vegas–Paradise Metro Area, 1,951,269; (2020) 641,903; Las Vegas–Henderson Metro Area, 2,265,461.
Character of the city
Las Vegas is a place of million-lightbulb signs and fantastic architecture, of readily visible wealth and carefully hidden poverty. It is a place of superlatives, both positive and negative. Within the city stand the largest glass pyramid in the world; one of the largest hotels in the country, with more than 5,000 rooms; and one of the most expensive hotels ever constructed, the Bellagio. The area along Las Vegas Boulevard and its adjoining near-downtown streets—the famous “Strip”—is the “City Without Clocks,” whose multibillion-dollar economy is devoted to servicing a wide array of impulses and addictions of many kinds. It is this Las Vegas, the flashy playground unofficially known as “Sin City,” that the American novelist and essayist Joan Didion once termed
the most extreme and allegorical of American settlements, bizarre and beautiful in its venality and in its devotion to immediate gratification.
Downtown Las Vegas is built to serve not residents but guests—tens of millions annually. Once derided as a cultural backwater, Las Vegas has evolved into an economic power that outstrips the output of whole countries. It is one of the country’s leading vacation destinations, drawing far more tourists than the Grand Canyon or Yellowstone National Park.
Britannica QuizMatch The City To Its Nickname QuizBeyond the bright lights of the Strip, however, lies a perfectly ordinary Western city, with neighbourhoods, churches, shopping centres, and strip malls. It is that city, and not the hotels and casinos, that draws thousands of new residents each year. This growth, coupled with its unusual economic basis, has made Las Vegas one of the wealthiest cities in the country, but it has also brought problems to the area. Las Vegas is among the country’s leaders in personal and property crimes, as well as suicide rates, alcohol consumption, and illegal drug use. The city also suffers the modern urban ills of air and water pollution, and the roads are choked with increasingly heavy traffic as new suburbs spring up in all directions.

City site
Las Vegas’s historic core lies at a site once occupied by marshes, freshwater springs, and grassy meadows (hence the city’s name; vegas is Spanish for “meadows”), long since covered by streets, buildings, and parking lots. The modern-day city sprawls across a broad, arid valley at an elevation of roughly 2,000 feet (610 metres). The valley fans out eastward from the picturesque, pine-clad Spring Mountains, whose highest point, Charleston Peak, rises above 11,910 feet (3,630 metres). To the north lie three lower ranges, the Pintwater, Spotted, and Desert mountains, and to the east are the McCullough and Sheep ranges. A wide pass between those two ranges leads to Hoover Dam and Lake Mead, the huge reservoir on the Colorado River impounded by the dam; Las Vegas Wash, the valley’s major drainage, leads through this route.
Surrounded by mountains, the Las Vegas Valley is a basin that collects the scant rainwater and snowmelt that reach it. Underlying that basin is a series of aquifers that once led out into small springs near the site of what is now the downtown area. These springs, most of which have dried up because of excessive groundwater pumping, historically flowed into the Colorado River toward the Pacific Ocean. The southern limit of the Great Basin reaches to just 15 miles (24 km) north of Las Vegas; its waters, which have no outlet to the sea, disappear into a vast inland desert.
The Las Vegas Valley is ecologically part of the Mojave Desert, whose characteristic plant is the Joshua tree. The smallest of the North American deserts, the Mojave supports significant human settlement only in the Las Vegas area and at a few points along the Colorado River. More than four-fifths of the city’s water supply comes from the Colorado River at Lake Mead. The remainder is pumped from underground aquifers. As more water has been removed from these aquifers, the sandy soils have subsided, leading to fissuring and structural damage of the surface and the formation of large sinkholes. These fissures are compounded by the damage caused by occasional earthquakes; the Las Vegas Valley, particularly its northwest quadrant, lies in an active fault zone.
