“Natural increase,” or births minus deaths, created 54 percent of Utah’s population growth over the past year — down from historical averages of around 66 percent. (And in 2010 amid the Great Recession, it accounted for 95 percent of Utah’s total growth).
“Natural increase is still strong. It’s still the major share of growth. But it’s been going down steadily since the onset of the Great Recession,” said Pam Perlich, director of demographics at the Kem C. Gardner Policy Institute at the University of Utah.
Perlich sees many potential causes for declining births here, even though Utah still has the nation’s top overall fertility rate, according to the U.S. Census Bureau. For one, “We’ve seen a collapse in the fertility rates of teenage women. That’s terrific.”
She said rates have also come down significantly for women in their 20s. “You see people delaying having children until their 30s, or late 20s. And when you start later, generally you have fewer.”
Meanwhile, net migration is accelerating — up by 2,728 people from the previous year, for an estimated total of 26,989. Perlich said most come from nearby states, but some comes from around the country and abroad.
“It’s the highest we’ve been since 2006,” Perlich said. “As the economy is growing, it is bringing people to the state for economic and educational opportunities.”
Steve Griffin | The Salt Lake Tribune 140 people from over 40 countries become new citizens of the United States of America as they take the Oath of Allegiance during a citizenship ceremony hosted by the U.S. Citizenship and Immigration Services at This Is The Place Heritage Park in Salt Lake City on Thursday.
“They are going to bring the characteristics from the outside world, rather than have the characteristics of the population that is already here. That intensifies the change process, the diversification along the lines of culture, nativity, language, ethnicity, origin,” she said.
The estimates were released Wednesday by the Utah Population Committee — which Perlich heads — and the Gardner Policy Institute. It is funded by the state to generate such estimates with a variety of local data, and act as a watchdog on estimates from the U.S. Census Bureau that affect federal funding in many areas.
The new state estimates said Utah had a population of 3.1 million on July 1 — up by more than 350,000 since the 2010 Census, or 12.7 percent.
Utah’s population grew by 59,000 people last year, essentially adding another Taylorsville. However, the reasons behind the growth are changing. Births continued a nine-year decline. But migration is increasing — with Utah’s healthy economy acting as a magnate to job seekers.
The estimates say Salt Lake County had the biggest numerical population increase among counties over the past year, up by 19,372 people (or 1.7 percent). Wasatch County had the biggest increase by percentage, up 4.1 percent in the year (or 1,227 people).

Salt Lake and Utah County combined have 56 percent of the state’s total population — but Utah County’s growth is especially accelerating, Perlich said, up by 14,350 people or 2.4 percent in the year.
Other Wasatch Front counties, plus Washington County, also help account for the biggest growth in the state, she said. Davis County attracted an additional 6,112 people, up 1.8 percent; Weber was up by 3,152, or 1.3 percent; and Washington County increased by 5,230, or 3.3 percent.
Also, “commuter ring” counties near the Wasatch Front are also seeing big growth. “Wasatch and Tooele County especially are growing rapidly,” she said — likely drawing commuters who want more land, less expensive housing and a better quality of life.
Meanwhile, much of rural Utah has stagnant or small growth. “The energy and natural resource counties especially are struggling,” she said. “Carbon, Emery, Duchesne, Uintah, Garfield, Kane, Piute and San Juan all have very slow growth.”
