U.S. Immigration Trends: Record Highs, Declines, and Uncertainties in 2023
The US immigrant population peaked at 53.3 million in early 2025 but has since declined to 51.9 million due to increased deportations and policy restrictions, marking the first decrease since the 1960s. Most immigrants originate from Latin America and Asia, with Mexico being the largest source. Recent policy shifts, including restrictions on asylum and deportation enforcement, have contributed to the decline, especially among unauthorized immigrants. Despite the decrease, the US remains the country with the largest immigrant population globally.
