Data from the Census Bureau and the Bureau of Labor Statistics show that the U.S. illegal immigrant population has surged 10%, growing from 10.2 million to 11.6 million between when President Joe Biden took office and April 2022. “This means that illegal immigrants accounted for some 1.35 million (about two-thirds) of the two million growth in the total foreign-born population since President Biden took office,” the Center for Immigration Studies reports.
