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. It is the most extensive U.S. state that does not border Canada, Mexico, or an ocean. Over two-thirds of Nevada's people live in the Las Vegas metropolitan area, which contains its three largest incorporated cities. Nevada's capital is Carson City. 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 mountains lie on the western edge. Approximately 86% of the state's land is owned by the US government under various jurisdictions, both civilian and military.
