Overview
- The undocumented population climbed by about 3.5 million from 2021 to reach 14 million in 2023, according to Pew’s new analysis.
- Roughly 6 million of those counted in 2023 had temporary protections from deportation, a group whose status can be changed by policy.
- The overall foreign-born population peaked at about 53.3 million in January 2025 and fell to roughly 51.9 million by June, marking the first decline in decades.
- Nearly all growth since 2021 came from countries other than Mexico, with non‑Mexican totals rising from 6.4 million to 9.7 million as Mexico’s share fell to about 30%.
- Pew links a 2024 slowdown and a 2025 pullback to asylum limits and intensified enforcement, while noting preliminary data and disputed claims such as DHS‑promoted figures of 1.6 million departures.
