Key Findings:• About 11 million undocumented immigrants lived in the United States as of 2022—3.3 percent of the country’s overall population. An additional 2.3 million removable immigrants were released into the United States between January 2023 and April 2024 and would also be targeted in any mass deportation operation. In 2022, nearly 90 percent of undocumented immigrants were of working age, compared to 61.3 percent of the U.S.-born population aged between 16 and 64, making undocumented immigrants more likely to actively participate in the labor force. Losing these working-age undocumented immigrants would worsen the severe workforce challenges that many industries have already been struggling with in the past few years. • Among the deported would be 1 million undocumented immigrant entrepreneurs, who generated $27.1 billion in total business income in 2022.
