During that time, entering the country grew more difficult and, throughout the recession, jobs in construction and other fields grew more scarce.
But in contrast, the number of migrants from Central America living in the United States illegally rose somewhat between 20, amid increased violence and economic uncertainty in the Northern Triangle region.
“There was an average of 386,000 annual unauthorized arrivals for the 2011-16 period, compared with 715,000 for the 2002-07 period.
That amounts to a 46 percent decline,” according to the report.
Cohn said, “but, from what we know, it appears that a majority of recent arrivals in 2016 are not unauthorized immigrants who crossed without documents, but people who arrived on legal visas and overstayed their deadlines to leave.”Such immigrants, who typically have the means to enter the country legally but have not been granted permission to stay beyond a certain period, “probably constituted most of the recent unauthorized immigrant arrivals in 2016,” according to the report.
The number of unauthorized immigrants living in the United States has dropped to the level it was in 2004, and Mexicans are no longer a majority of this population. The 2017 unauthorized immigrant total is a 14% drop from the peak of 12.2 million in 2007, when this group was 4% of the U. Mexicans made up less than half of all unauthorized U. immigrants (47%) in 2017 for the first time, according to the Center’s estimate, compared with 57% in 2007. Meanwhile, the total from other nations, 5.5 million in 2017, ticked up from 2007, when it was 5.3 million.Here are five facts about the unauthorized immigrant population in the U. There were 10.5 million unauthorized immigrants in the U. This growth was fueled mainly by immigrants from the Northern Triangle nations of El Salvador, Guatemala and Honduras. The number of Mexican unauthorized immigrants declined since 2007, while the total from other nations ticked up.This decline is due mainly to a large drop in the number of new unauthorized immigrants, especially Mexicans, coming into the country. Their numbers (and share of the total) have been declining in recent years: There were 4.9 million Mexican unauthorized immigrants living in the U. The number of unauthorized immigrants has grown since 2007 from both Central America and Asia.The origin countries of unauthorized immigrants also shifted during that time, with the number from Mexico declining and the number rising from Central America and Asia, according to the latest Pew Research Center estimates. There were 1.5 million Central American unauthorized immigrants in 2007 and 1.9 million in 2017.Pew notes that, according to survey data by the Mexican government, “the majority cited family reunification as the main reason” for returning to Mexico.And there has also been a sharp decrease in the number of “recent arrivals” — immigrants who entered the country within the last five years.The unauthorized immigrant population decreased in a dozen states: Arizona, California, Colorado, Florida, Georgia, Illinois, Michigan, Nevada, New Jersey, New Mexico, New York and Oregon. A declining share of unauthorized immigrants have lived in the U. for five years or less – 20% of adults in 2017, compared with 30% in 2007.In five states, the unauthorized immigrant population rose over the same period: Louisiana, Maryland, Massachusetts, North Dakota and South Dakota. About two-thirds (66%) of unauthorized immigrant adults in 2017 had been in the U. In 2017, unauthorized immigrant adults had lived in the U. for a median of 15.1 years, meaning that half had been in the country at least that long.The study, published by the Pew Research Center on Tuesday, put the number of undocumented immigrants in the United States at 10.7 million in 2016, down from a peak of 12.2 million in 2007.As Pew analyzed new data from recent years, its researchers found that “it wasn’t just that the numbers declined, but also who these unauthorized immigrants are had changed since 2007,” said D’Vera Cohn, a senior writer at Pew Research.
