The unauthorized immigrant population in the United States reached 10.5 million in 2021. That was a modest increase over 2019 but nearly identical to 2017.
The U.S. population grew by 24.5 million from 2010 to 2022, and Hispanics accounted for 53% of this increase.
The unauthorized immigrant population’s size and composition has ebbed and flowed significantly over the past 30 years.
Most live in Germany, the UK, Italy and France, and about half had arrived in Europe in recent years. Overall, these migrants account for less than 1% of Europe’s total population.
The increase from these countries exceeded modest growth of the overall foreign-born population and came amid a decline in immigrants from Mexico.
About 275,000 babies were born to unauthorized-immigrant parents in 2014, a decline from 330,000 in 2009.
For the first time on record, more non-Mexicans than Mexicans were apprehended at U.S. borders in 2014 by the Customs and Border Patrol.
The largest wave of immigration in history from a single country to the United States has come to a standstill.
The U.S. population in 2010 included 39.9 million foreign-born residents. This estimate, the latest available for the foreign-born population, is 1.5 million, or 4%, higher than the survey’s 38.5 million estimate in 2009.
There were 11.9 million unauthorized immigrants living in the United States in March 2008. The size of the unauthorized population appears to have declined since 2007.
