U.S. Unauthorized Immigration Population Trends, 1990-2012

Explore population trends from a new analysis of the unauthorized immigrant population in the United States based on Pew Research Center estimates. In 2012, an estimated 11.7 million unauthorized immigrants lived in the U.S., up from a recent low of 11.3 million in 2009. Since 1990, the nation’s unauthorized immigrant population has more than tripled. For more, see Population Decline of Unauthorized Immigrants Stalls, May Have Reversed.

Notes: Shading surrounding line indicates low and high points of the estimated 90% confidence interval. White data markers indicate the change from the previous year is statistically significant (for 1995, change is significant from 1990).
