5 facts about illegal immigration in the U.S.
The number of unauthorized immigrants in the U.S. has stabilized in recent years after decades of rapid growth. But the origin countries of unauthorized immigrants have shifted, with the number from Mexico declining since 2009 and the number from elsewhere rising, according to new Pew Research Center estimates.
Here are five facts about the unauthorized immigrant population in the U.S.
1 There were 11.1 million unauthorized immigrants in the U.S. in 2014, a total unchanged from 2009 and accounting for 3.5% of the nation’s population. The number of unauthorized immigrants peaked in 2007 at 12.2 million, when this group was 4% of the U.S. population.
2 Mexicans made up 52% of all unauthorized immigrants in 2014, though their numbers had been declining in recent years. There were 5.8 million Mexican unauthorized immigrants living in the U.S. that year, down from 6.4 million in 2009, according to the new Pew Research Center estimates.
3 The number of unauthorized immigrants from nations other than Mexico grew by 325,000 since 2009, to an estimated 5.3 million in 2014. Populations went up most for unauthorized immigrants from Asia and Central America, but the number also ticked up for those from sub-Saharan Africa. Increases in the number of unauthorized immigrants from other countries mostly offset the decline in the number from Mexico.
4 Six states accounted for 59% of unauthorized immigrants in 2014: California, Texas, Florida, New York, New Jersey and Illinois. But some state populations had changed since 2009, despite the stable trend at the national level. From 2009 to 2014, the unauthorized immigrant population decreased in seven states: Alabama, California, Georgia, Illinois, Kansas, Nevada and South Carolina. In all of them, the decline was due to a decrease in unauthorized immigrants from Mexico. In six states, the unauthorized immigrant population rose over the same time period: Louisiana, Massachusetts, New Jersey, Pennsylvania, Virginia and Washington. In all of these but Louisiana, the increases were due to growth in unauthorized immigrant populations from nations other than Mexico. In Louisiana, it was an increase in Mexican unauthorized immigrants that drove the overall increase in the number of unauthorized immigrants.
5 A rising share of unauthorized immigrants have lived in the U.S. for at least a decade. About two-thirds (66%) of adults in 2014 had been in the U.S. at least that long, compared with 41% in 2005. A declining share of unauthorized immigrants have lived in the U.S. for less than five years – 14% of adults in 2014, compared with 31% in 2005. In 2014, unauthorized immigrant adults had lived in the U.S. for a median of 13.6 years, meaning that half had been in the country at least that long. Only 7% of Mexican unauthorized immigrants had been in the U.S. for less than five years in 2014, compared with 22% of those from all other countries.
