After large quantities of silver were discovered at the Comstock Lode of 1859, Nevada’s population began to swell. Nevada became a state in 1864, and even today, people swarm to the state with the hope of striking it rich. Legalized gambling in the state is a big business. In fact, Las Vegas, the state’s largest city, is based on gambling and tourism. Over two-thirds of the state’s population lives in Clark County, the county that contains the Las Vegas metro area. Gaming brings in billions of dollars per year to the state, but tourists also come to ski at Lake Tahoe, hike in the Sierra Nevada Mountains, and explore the Mojave Desert. Other industries in Nevada include gold mining, farming, food processing, and the printing and publishing business. Nevada is a large state with plenty to offer.
