With the establishment of Hill Air Force Base in northern Davis County and southern Weber County, there was a surge of civilian employment after World War II. The county doubled in population between 1940 and 1950, and doubled again between 1950 and 1960 as part of the nationwide suburb boom that was occurring at the time. By 1990 there were 188,000 residents, and in 2000, there were 239,000. By 2030, the county is expected to have a population of about 360,000.
