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. This decline is due mainly to a large drop in the number of new unauthorized immigrants, especially Mexicans, coming into the country. 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.
Here are five facts about the unauthorized immigrant population in the U.S.
1There were 10.5 million unauthorized immigrants in the U.S. in 2017, representing 3.2% of the total U.S. population that year. 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.S. population.
2The number of Mexican unauthorized immigrants declined since 2007, while the total from other nations ticked up. Mexicans made up less than half of all unauthorized U.S. immigrants (47%) in 2017 for the first time, according to the Center’s estimate, compared with 57% in 2007. 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.S. in 2017, down from 6.9 million in 2007.

Meanwhile, the total from other nations, 5.5 million in 2017, ticked up from 2007, when it was 5.3 million. The number of unauthorized immigrants has grown since 2007 from both Central America and Asia. There were 1.5 million Central American unauthorized immigrants in 2007 and 1.9 million in 2017. This growth was fueled mainly by immigrants from the Northern Triangle nations of El Salvador, Guatemala and Honduras. The number from Asia, 1.3 million in 2007, rose to 1.5 million in 2017.
At the same time, the number of unauthorized immigrants from South America and Europe decreased between 2007 and 2017. Other large regions (the Caribbean, Middle East-North Africa, sub-Saharan Africa and the rest of the world) did not change significantly during that time.
