In between 2007 and 2017, the total number of undocumented immigrants living in the United States shrank by 14 percent. However, they still made up 23 percent of the total foreign-born population in 2017.
2017 was the first year in which Mexican people were not an absolute majority among undocumented immigrants in the U.S.. In fact, immigrant inflow from the U.S. Southern neighbor has declined significantly since 2007, while more undocumented immigrants entered the U.S. from Central and South America as well as Asia.
So where do these undocumented immigrants live in the U.S.?
California and Texas are the states hosting the biggest populations of undocumented immigrants, according to estimates by Pew Research Center. The two states were supporting undocumented populations of 2 million people and 1.6 million people in 2017 respectively. New York, Florida, Illinois and several more states along the Eastern seaboard also have a large population of undocumented people.
