Recent data from U.S. Customs and Border Protection (CBP) and government population surveys reveal a significant decline in illegal immigration across the United States in 2025.
After years of fluctuations and concerns about border security, the latest statistics indicate a historic drop in illegal border crossings and encounters, as well as shifts in the illegal immigrant population within the country. This article explores the latest trends, official figures, and implications of this downward trajectory in illegal immigration.
Historic Low Illegal Border Crossings in 2025
According to CBP’s monthly updates, the number of illegal border crossings along the southwest border has plummeted sharply in 2025. In May 2025 alone, the Border Patrol encountered 8,725 illegal aliens crossing between ports of entry, marking a staggering 93% decrease compared to May 2024, when encounters numbered 117,905.
This trend holds throughout the year, with February 2025 border apprehensions at 8,347, a 71% drop from January 2025 and a 94% decline from February 2024. This reduction reflects increased enforcement efforts and policy changes aimed at securing the border and deterring unlawful entry.
Furthermore, the CBP reports that zero illegal aliens were released into the interior of the U.S. in May 2025, compared to over 62,000 released in May 2024. This shift highlights a more stringent immigration enforcement approach under the current administration, prioritizing removal over release and reinforcing border security measures.
Daily nationwide apprehensions have also reduced to record historic lows, averaging approximately 952 encounters per day in May 2025—the second-lowest average in CBP history.
Illegal Immigrant Population Trends
While the border apprehension numbers point to a decline in new unauthorized entries, government surveys reveal complex dynamics within the existing unauthorized immigrant population in the U.S.
The January 2025 Current Population Survey (CPS) projects that the total illegal immigrant population in the country is approximately 15.8 million, including those with pending asylum and parole status. This represents an increase from earlier years, indicating that while new crossings have decreased, the net unauthorized population remains substantial.
However, it is essential to note that this number reflects the stock of illegal immigrants residing in the U.S., not the flow of new entries. The increase since 2021 includes those who have legalized their status, those departing the country voluntarily or through removal, and demographic factors such as birth rates and mortality.
Other reputable sources like Pew Research Center estimated the unauthorized immigrant population at around 11 million in 2022, a figure somewhat lower but based on different methodologies and data sets.
Context and Implications
These statistics indicate a turning point with illegal border crossings falling to historic lows in 2025, while the existing population of unauthorized immigrants remains elevated.
The decline in border encounters can be attributed to enhanced border patrol activities, enforcement policies emphasizing swift removal, and international cooperation to curb illegal migration. The sizeable unauthorized immigrant population within the U.S. underscores ongoing challenges involving integration, border security, and immigration reform.
Conclusion
The latest official reports confirm that illegal immigration into the United States is falling significantly in 2025, with border apprehensions down by over 90% compared to previous years. This reduction is the result of focused enforcement actions and policy measures to secure the borders more effectively.
Despite this progress, the total unauthorized immigrant population within the country remains large, highlighting the complex nature of immigration issues in America. Policymakers continue to face the dual challenge of maintaining robust border security while addressing the needs and status of millions already living in the U.S. illegally.
