OECD reports second straight decline in migration to member countries

OECD migration falls again as Southern Europe and Japan buck trend

In North America, Mexico steps up enforcement while the U.S. Supreme Court takes up a challenge to Trump’s border asylum ban.

Story Summary

An OECD report shows migration to advanced economies fell 1.6% in 2025, the second annual drop, even as legal admissions rose in Portugal, Italy, Spain and Japan while declining in the United States, Canada and the United Kingdom. The aggregate downturn coincides with a North American enforcement push—Mexico dispersing migrant caravans and the U.S. Supreme Court taking up an asylum‑ban case—shaping access to protection and the terms of cross‑border cooperation. The unresolved tension is whether these legal and operational choices, alongside diverging intake policies, entrench a broader contraction or simply redistribute movement, with consequences for labor markets, integration capacity and regional burden‑sharing.

OECD records second straight drop in migration to developed countries, with Southern Europe and Japan diverging as US border policy heads to court

Narrative Snapshot

European and Asian outlets foreground the OECD’s aggregate finding while highlighting regional exceptions, whereas North and Latin American coverage centers on border management and litigation. Le Monde emphasizes a split within the OECD: rising legal immigration to Portugal, Italy, and Spain versus declines in Canada, the United States, and the United Kingdom. The Bangkok Post distills the headline metric of a 1.6 percent fall in 2025 and the fact that this marks a second consecutive annual decline. The Japan Times focuses on Japan as an outlier with rising inflows against the OECD-wide downturn.

US and Latin American reporting pivot from stock measures to enforcement and legality. The New York Times reports that Mexico has cooperated to significantly slow migrant flows but that the new White House chief of staff considers this insufficient. Clarin details operational effects in Mexico, citing an official account of 24 migrant caravans disbanded in the south since Donald Trump’s return, with President Claudia Sheinbaum crediting Mexican authorities’ information and attention strategies for preventing northward movement. The Guardian spotlights the legal front: the US Supreme Court’s decision to hear a case on Trump’s executive order banning asylum applications at the US‑Mexico border, after lower courts found it illegal.

What Happened

An OECD report released on Thursday finds that migration to developed countries fell for the second year in a row in 2025, declining by 1.6 percent from 2024, according to the Bangkok Post. Le Monde reports divergent regional patterns within that aggregate: legal immigration rose strongly in Portugal, Italy, and Spain, while it decreased in Canada, the United States, and the United Kingdom. The Japan Times notes that Japan’s immigration increased, contrasting with declines across other OECD members.

In North America, the New York Times reports that Mexico has cooperated to significantly slow migrant flows, though the new US White House chief of staff says this is not enough. Clarin cites a Mexican commissioner stating that 24 migrant caravans have been disbanded in southern Mexico since Trump’s return, with President Sheinbaum highlighting authorities’ role in preventing their northward transit. The Guardian reports that the US Supreme Court agreed to consider the Trump administration’s ban on asylum at the US‑Mexico border after lower courts ruled the executive order illegal.

Why It Matters

The OECD’s assessment suggests a bifurcated landscape in which some member states increase legal admissions while others reduce them, a configuration with implications for labor markets, integration systems, and regional burden-sharing. Le Monde’s account of Southern Europe’s rising legal immigration and the Japan Times’ note on Japan’s increase highlight that mobility is not uniformly contracting across advanced economies, even as the Bangkok Post underscores a second straight annual decline overall.

Simultaneously, the US‑Mexico dimension is being shaped by both operational cooperation and high‑stakes litigation. The New York Times’ reporting on US expectations of Mexican enforcement alongside Clarin’s description of caravan dispersals reflects tightening controls on irregular movement. The Guardian’s coverage of Supreme Court review of an asylum ban elevates legal questions about executive authority and access to protection at the border. Together, these dynamics inform how governments and international bodies assess capacity, uphold legal norms, and calibrate cross‑border cooperation amid shifting inflows.

Diverging Narratives

The OECD-centric coverage presents a statistical downturn tempered by regional exceptions. Le Monde and the Bangkok Post align on the overall decline while highlighting that Southern Europe’s legal channels expanded, and the Japan Times stresses Japan’s contrasting increase. This frames migration management as varying by national context rather than a uniform contraction.

North American and Mexican reporting foreground enforcement and legality rather than aggregate flows. The New York Times highlights a White House perspective that Mexican cooperation, while significant, remains inadequate. Clarin, by contrast, emphasizes Mexican government statements about concrete outcomes—24 caravans disbanded and prevented from advancing north—framed by President Sheinbaum as the product of information and attention strategies. The Guardian introduces a judicial vector: the Supreme Court’s agreement to hear a challenge to an asylum ban after adverse lower‑court rulings. These strands do not dispute the OECD data; they situate it within operational and legal contests over how borders are managed and who can claim protection.

What Happens Next

Three decision points will shape trajectories. First, the US Supreme Court’s review of the asylum ban, as reported by the Guardian, will determine whether lower‑court findings of illegality stand or are overturned. Upholding the ban would reconfigure access to asylum processing at the border; striking it down would constrain executive use of such restrictions. Second, bilateral enforcement dynamics bear watching: the New York Times notes US claims that Mexico’s cooperation is insufficient, while Clarin details caravan dispersals. Further US statements or measures pressing for additional Mexican action, and continued Mexican reporting on caravan outcomes, will signal whether operational tightening persists or shifts. Third, the OECD trendline itself—decline overall with rises in Southern Europe and Japan per Le Monde and the Japan Times—sets a baseline; subsequent national admissions data will indicate whether these increases endure or converge with broader OECD declines.
