Overview
- The total immigrant population fell from 53.3 million in January to 51.9 million in June 2025, marking the first shrinkage since the 1960s, according to Pew’s preliminary analysis.
- The unauthorized population reached 14 million in 2023, with more than 40% holding temporary protections from deportation, and Pew says the 2025 count has likely begun to decline but remains near that level.
- Growth in 2021–23 was driven largely by people from countries other than Mexico, whose numbers rose from 6.4 million to 9.7 million as the Mexican total edged up to 4.3 million.
- Pew links the recent shift to policy moves that slowed growth in late 2024 under President Joe Biden and to intensified enforcement, arrests and removals in 2025 under President Donald Trump.
- The labor force lost more than 750,000 immigrant workers between January and June 2025, while Pew warns survey nonresponse may undercount immigrants and notes DHS Secretary Kristi Noem’s claim of 1.6 million departures lacked department data.
