Nevada is a state in the western, mountain west, and southwestern regions of the United States. Nevada is the 7th most extensive, the 35th most populous, and the 9th least densely populated of the 50 United States. Nearly three-quarters of Nevada's people live in Clark County, which contains the Las Vegas–Paradise metropolitan area where the state's three largest incorporated cities are located. Nevada's capital is Carson City. Nevada is officially known as the "Silver State" due to the importance of silver to its history and economy. It is also known as the "Battle Born State", because it achieved statehood during the Civil War; "Sagebrush State", for the native eponymous plant; and "Sage hen State."
Nevada is largely desert and semiarid, with much of it located within the Great Basin. Areas south of the Great Basin are located within the Mojave Desert, while Lake Tahoe and the Sierra Nevada lie on the western edge. Approximately 86% of the state's land is owned by various jurisdictions of the U.S. federal government, both civilian and military.
