The growth of the U.S. Latino population — once the nation's fastest growing — slowed considerably over the past seven years and slipped behind that of Asian Americans amid declining Hispanic immigration and birth rates, a study released Thursday found.
The Pew Research Center study, which analyzed U.S. Census Bureau data, found that the U.S. Hispanic population grew annually on average by 2.8 percent between 2007 and 2014.
That's down from the 4.4 percent annual growth from 2000 to 2007, before the Great Recession.
By comparison, the Asian American population grew around 3.4 percent on average annually during the same period.
William H. Frey, a demographer with the Brookings Institution's Metropolitan Policy Program, the slower growth is largely a factor of the economy. A slower economy is influencing families to hold off on having more children, and it's discouraging migration amid stronger border enforcement, he said.
Kenneth M. Johnson, a senior demographer at the University of New Hampshire's Carsey School of Public Policy, said U.S. Hispanic women between the ages of 20 to 24 have seen a 36 percent decline in birth rates.
"That's by far the largest decline of any other group," Johnson said.
Despite slowing population growth, Latinos still accounted for 54 percent of the nation's population growth between 2000 and 2014, according to the nonpartisan Pew Research Center.
Regional growth patterns also have changed some following the economic downturn of 2007 reflecting the changing economies of states, the study found.
Counties in the South continued to account for the largest share of the nation's Hispanic population growth — 43 percent between 2007 and 2014. Among the other fastest-growing counties for Latinos were Luzerne County in Pennsylvania, Beadle County in South Dakota, Duchesne County in Utah and Burleigh County in North Dakota.
"Latinos are coming to Utah because the government here is doing a lot to create jobs," said Rogelio Franco of Entre Latinos, a Salt Lake City, Utah advocacy group that works to integrate Hispanics into the state. Entre Latinos was not affiliated with the study.
Franco said he thinks the declining birth rate is a result of Latino millennials holding off on having children while pursuing their education.
"They are planning more," Franco said. "They are focusing on other things."
The growth in North Dakota's statewide Latino population nearly doubled to 18,000, making it the state with the highest Hispanic growth rate over seven years. Though small in numbers compared to states like California and Texas, the rise in Latino residents has put pressures on local governments and nonprofits to accommodate the new residents.
For example, in 2014 Catholic nuns from Mexico were sent to North Dakota to help serve new Hispanic parishioners in that state.
North Dakota had experienced an oil boom until recently, attracting workers from around the country. It remains one of the least diverse states in the country.
"Latino population growth has become less concentrated in counties with historically large Latino populations and whose Latino population grew by at least 10,000," the study's authors wrote.
Though the growth has slowed in the last seven years, the Latino population in the South has exploded when examined over 14 years.
From 2000 to 2014, Latino populations in Tennessee and South Carolina, for example, nearly tripled.
North Carolina also saw its population spike 136 percent since 2000, the report said.
Mauricio Castro, an organizer with the North Carolina Congress of Latino Organizations, said Latino immigrants coming to the region tend to work in the construction or service industry.
Still, between 2007 and 2014, nearly 40 counties experienced declines in the percentage of Latinos. Most of those counties were in Colorado, New Mexico and Texas — states with traditionally large Hispanic populations.
Frey said once the U.S. economy starts picking up, he expects to see a return of higher rates of immigration and increase births.
"This is not the end of Latino growth in the United States by any means," Frey said.
