Estimated Undocumented Immigrants by State
Illegal aliens, undocumented immigrants, or unauthorized residents, no matter which term is used, all refer to people who live in the United States but do not have proper government authorization. This population includs mostly two groups: individuals who entered the U.S. without inspection, and non-immigrant visitors who entered the U.S. legally but over stayed their visas.
The map below shows estimates of illegal immigrant population by state of residence, using data from the Department of Homeland Security (2015) and Pew Research Center (2016). Click on image to see larger map.
