Utah (/ˈjuːtɔː/ or i/ˈjuːtɑː/) (Arapaho: Wo'tééneihí' ) is a state in the Western United States. It became the 45th state admitted to the Union on January 4, 1896. Utah is the 13th-most extensive, the 34th-most populous, and the 10th-least-densely populated of the 50 United States. Approximately 80% of Utah's 2,817,222 people live along the Wasatch Front, centering on Salt Lake City, leaving vast expanses of the state nearly uninhabited and making the population the sixth most urbanized in the U.S. Utah is bordered by Colorado on the east, Wyoming on the northeast, Idaho on the north, Arizona on the south, and Nevada on the west. It also touches a corner of New Mexico.
Utah is the most religiously homogeneous state in the Union. Approximately 63% of Utahns are reported to be members of The Church of Jesus Christ of Latter-day Saints or LDS (Mormons), which greatly influences Utah culture and daily life, and it is the site of the Salt Lake Temple.
The state is a center of transportation, education, information technology and research, government services, mining, and a major tourist destination for outdoor recreation. According to the U.S. Census Bureau's population estimates, Utah was the fastest-growing state in the United States as of 2008. St. George, Utah, was the fastest–growing metropolitan area in the United States from 2000 to 2005. A 2012 Gallup national survey found Utah overall to be the "best state to live in" based on 13 forward-looking measurements including various economic, lifestyle, and health related outlook metrics.
