# US-Mexico border apprehensions fall to lowest level since 1967 as Trump enforcement policies collapse irregular crossings > US Customs and Border Protection apprehended just 42,757 migrants at the southwest border in the first half of fiscal year 2026, placing annual apprehensions on track for the lowest total since 1967; January 2026 encounters fell 84% from January 2025, and even a March 2026 rebound of 8,300 crossings was 15% above March 2025 but remained historically minimal by any prior-decade measure **Meta:** type: event · date: 2026-02-02 · heads: 谁说了算, 悄然的转变 · 6 takes · 5 lenses · 2 regions ## Summary US Customs and Border Protection reported a collapse in irregular migration at the US-Mexico southwest land border through the first half of fiscal year 2026 (October 2025 to March 2026), with Border Patrol apprehending 42,757 migrants, on track for the lowest annual total since 1967. January 2026 encounters fell 84% from January 2025. March 2026 saw approximately 8,300 detected crossings, 15% above March 2025 but from a baseline that was already at historic lows. The El Centro, California sector saw the largest percentage rebound, with crossings up 112% between March 2025 and March 2026, though still at a low absolute level. CBP attributed the historically low numbers to enforcement measures implemented from January 2025 onward, including expedited removal authority expansions, third-country deportation agreements, and asylum restriction mechanisms. Total fiscal year 2025 southwest border encounters were 237,538. ## The split The Trump administration framed the numbers as evidence of successful border deterrence and cited the statistics in ongoing congressional negotiations over the Reconciliation Bill's immigration provisions. Civil liberties and immigrant rights organisations, including WOLA, noted that the same period saw expanded ICE detention capacity, reports of harsh conditions in Southwest detention facilities, and the effective closure of legal asylum pathways that had previously provided an alternative route to irregular entry. Mexican government officials attributed part of the decline to Mexico's own enforcement operations on its southern border and in transit corridors, under arrangements with the US. Central American human rights organisations reported that the drop in border crossings reflected migrants being stopped or turned back at earlier points in the journey, not a reduction in the underlying push factors driving migration. ## By the numbers - 42,757 total Border Patrol southwest border apprehensions in H1 FY2026 - 84% decrease in January 2026 encounters versus January 2025 - 8,300 estimated crossings in March 2026 (+15% from March 2025, but from historical lows) - 237,538 total southwest border encounters in full FY2025 - On track for lowest annual apprehension total since 1967 - 112% increase in El Centro sector between March 2025 and March 2026 ## Why it matters The collapse in [US Mexico Border](/zh/entity/place/us-mexico-border) encounters is the sharpest peacetime reduction in southwest border migration ever recorded in the modern CBP data era and represents a fundamental shift in the operative migration dynamics of the western hemisphere's primary irregular migration corridor. Whether the reduction reflects durable deterrence or a temporary suppression that will rebound as migration push factors persist is the central policy question for the remainder of the decade. The numbers also have direct implications for Mexico, Central America, and Venezuela, where the US border has historically served as the terminal point for migration that is no longer reaching it. ## What to watch - Whether the March 2026 uptick in El Centro and other sectors represents the beginning of a rebound - Full fiscal year 2026 total and PAHO/IOM assessment of western hemisphere migration pattern shifts - Conditions in Mexican and Central American migration detention as northward flow is blocked at earlier stages - How the Reconciliation Bill's immigration provisions affect border enforcement authority and legal migration pathways ## Regional takes (batched by bias / lens) ### Nonpartisan research institution; authoritative analysis of CBP statistics over the long historical arc - **Pew Research Center** (United States, en) — Pew Research reported on February 2, 2026 that migrant encounters at the US-Mexico border had fallen to their lowest level in more than 50 years, based on CBP data.
