Numbers, Facts and Trends Shaping Your World
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 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.
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.
