If planners at the State Office of Planning and Budget are right, Utah will have 2.4 million residents by 2010 - and Davis, Morgan and Washington counties will be adding residents faster than any other areas in the state.
Projections released by the office's data resources section shows that Utah will grow by an estimated 746,000 people over the next 12 years or at 1.7 percent each year."Utah can be expected to experience continued relatively good growth through the remainder of the 20th century and well into the 21st. The population growth rate in Utah is projected to be almost twice the growth projected for the nation," the report says.
If the projections hold true, census takers in 1990 will find Utah has a population of 1.8 million and just over 2 million in 2000. Utah is expected to have close to 1.7 million people by the end of 1988.
Much of the growth over the next 22 years will be from births. "It is projected that 910,00 births will occur to Utah residents between 1987 and 2010. While the number of births is expected to taper off for the next few years, another surge is expected in the late 1990s," the report said, noting that the number of deaths will increase as more people move into the 60 years and older population group.
The report also predicted that in-migration will exceed out-migration by 180,000 over the projected period.
Washington, Davis and Morgan counties are projected to get more than 2 percent of the population increase each year. Washington County is expected to lead the state's population growth with a 3.1 yearly increase. The county's 1987 estimated population of 41,000 could rise to more than 65,000 by 2010.
Davis County, with the second- fastest projected population growth, should more than double its 1980 population of 148,000 to 300,000 in 2010. The county's estimated population in 1987 was 179,000.
Morgan County is expected to sustain a steady 2.4 percent annual population increase, reaching close to 10,000 people by 2010, projections show.
The projections match recent growth patterns in Utah cities.
According to U.S. Census Bureau data compiled in 1986, the Davis County cities of Farmington, Clinton, Layton, Centerville and Woods Cross were among the state's top 10 fastest-growing cities. The figures aren't expected to be updated until the census is taken in 1990. Farmington, Utah's second-fastest-growing town, added almost 3,000 residents to its 1980 population of 4,691. Layton grew 33 percent to claim more population than towns traditionally considered among Utah's largest _ Bountiful and Logan.
Salt Lake County's population is expected to grow slightly faster than the state's yearly average during the next two decades. If recent trends are any indication, four cities in the south end of the county will experience most of the growth.
For example, the 1986 figures showed the population of West Jordan had grown more than 62 percent since 1980, making it the fastest-growing city in the state. South Jordan, Riverton and Sandy were also on the top 10 list.
The only city on the fastest-growing list outside of Davis and Salt Lake counties was St. George. It is expected to continue to absorb much of the growth projected for Washington County.
Summit, Cache and Kane are the only other counties projected to add population faster than the state average.
While no Utah counties are expected to lose population over the next two decades, expansion will be smallest in Daggett and Grand counties. Grand County is expected to add only 1,000 people to its present estimated population of 6,700. Daggett is expected to add 100 people to its current estimated population of 700.
