Grantsville, the second most populous city in Tooele County, Utah, United States. It is part of the Salt Lake City, Utah Metropolitan Statistical Area. The population was 9,063 on the 2011 report of the American Community Survey, a branch of the U.S. Census Bureau. The city has grown slowly and steadily throughout most of its existence, but rapid increases in growth occurred during the 1970s and 1990s. Recent rapid growth has been attributed to the nearby Deseret Peak recreational center, the Miller Motorsports Park raceway and to the newly built Wal-Mart Distribution Center located just outside the city. It is quickly becoming a bedroom community for commuters into the Salt Lake valley. ^source
