Davis County is often characterized as a bedroom community. According to the US Census Bureau's 2004 American Community Survey, 42.3% of the population works in another county.[2] South Davis County commuters who work in Salt Lake County frequently encounter commuting time traffic bottlenecks between Davis and Salt Lake Counties. The Legacy Highway and Commuter Rail FrontRunner projects are under construction to ease this problem.

Davis County's largest employer is Hill Air Force Base. Hill AFB is a dominant feature of the economy of Davis County. Earnings of civilians at Hill AFB are almost double the state average. Hill AFB accounts for about 12% of the economy of Davis County and about 2.6% of the economy of Utah.[3] Hill AFB provides employment for nearly 23,000 military and civilian personnel (approximately 4,500 active duty, 1,200 reservists, 13,000 federal civil servants, and 4,000 civilian contractors).[4] Other large employers include Davis School District, Lagoon Amusement Park, and Lifetime Products.
