Utah is a western state of the United States. It was the 45th state admitted to the Union, on January 4, 1896. Approximately 80% of Utah's 2,736,424 people live along the Wasatch Front, centering on Salt Lake City. This leaves vast expanses of the state nearly uninhabited, making the population the sixth most urbanized in the U.S. The name "Utah" is derived from the name of the Ute tribe and means "people of the mountains" in the Ute language. Utah is bordered by Arizona on the south, Colorado on the east, Wyoming on the northeast, Idaho on the north and Nevada on the west. It also touches a corner of New Mexico.
