The United States is the world’s top destination for Haitian migrants, who in recent years have fled an array of disasters and crises. Compared to other immigrant groups in the United States, the nearly 731,000 Haitians are more likely to be naturalized citizens, arrive through family-based pathways, and work in the service industry, as this data-rich article details.
Turkey is home to the world’s largest refugee population, a fact that has been a source of pride, a geopolitical tool, and a logistical challenge. This article shows how the millions of Syrians who have arrived since 2011 comprise just one aspect of Turkey’s rich and complex migration history. The country has been a significant host, a transit point for individuals heading to Europe, and a source of migrant laborers.

Amid the highest Caribbean maritime migration levels in a generation, the Biden administration is relying on a carrot-and-stick strategy it honed amid record unauthorized migration at the U.S.-Mexico border. The approach, combining limits on asylum, expanded legal pathways, and international enforcement partnerships, could be increasingly important if maritime migration rises, as this article explains.
Ecuador has emerged as a significant destination for Venezuelan migrants, and is also a sizable origin for people heading to the United States and Spain. The Andean nation has found itself enmeshed in the Americas' evolving mobility trends and has responded with a mix of policies that have produced some unforeseen outcomes. This country profile evaluates recent trends and puts them in historical context.
The more than 1.3 million Vietnamese immigrants in the United States are the result of nearly 50 years of migration that began with the end of the Vietnam War in 1975. While early generations of Vietnamese immigrants tended to arrive as refugees, the vast majority of recent green-card holders obtained their status through family reunification channels. This article takes a look at the sixth-largest U.S. immigrant population.

Severe weather, rising seas, and other consequences of global climate change are affecting the way people live, work, and move around the planet. While there is no clear, direct line between the impacts of climate change and changing human movement, there are indications that the warming planet is indirectly creating or altering patterns of migration. Our podcast Changing Climate, Changing Migration dives deep into the intersection of climate change and migration to separate fact from fiction.

Migrant millionaires are once again on the move, though headed to new destinations amid fallout from the COVID-19 pandemic and Russia's invasion of Ukraine. While wealthy new arrivals can help provide a healthy tax base and invest in local economies, they can upset housing markets and exacerbate wealth disparities, as this article describes.
Poland hosts millions of Ukrainians who fled Russia’s invasion. While the new arrivals have tended to have been greeted warmly, many have questions about the future. As the months pass, many displaced Ukrainians wonder when and if they will return to their native country. This article, based on interviews with dozens of displaced Ukrainians in Poland, examines their experiences.
The Biden administration’s policy to expel some Venezuelan border arrivals to Mexico marks a significant reversal. For the first time, the U.S. government is invoking the controversial Title 42 expulsions policy not on public-health grounds but as an explicit immigration enforcement measure. The expulsions are being paired with a new humanitarian parole program for up to 24,000 Venezuelans. This article assesses the policy and the uneven treatment of humanitarian migrants by nationality.
Spain has an unconventional immigration system. The national government is primarily responsible for border control, granting legal status to migrants, and other issues, but integration is mostly handled by regional and local governments, allowing for some pioneering policies at the subnational level. This article explores what this system has meant for Catalonia and its capital, Barcelona, which have been considered to be a model throughout Europe.
Mexicans are by far the largest immigrant group in the United States, accounting for nearly one-fourth of all immigrants. However their numbers have been declining and in 2021 there were 1 million fewer than a decade ago. At the same time, despite years in which more new migrants came from China and India, Mexicans once again count as the largest group of new arrivals. This article outlines the changing shape and composition of this immigrant population.

Tens of thousands of migrants have gone missing in Mexico in recent years, with the country having one of world's highest rates of disappeared persons. In 2015, the Mexican government created institutions to investigate these cases and work with the missing migrants' families, who are often their most vocal advocates. This article explores the reasons why migrants disappear, as well the institutions established to investigate cases and their impact.
The European Union has tried to leverage development assistance to address root causes of migration from Africa, including poverty, instability, and conflict. The EU Emergency Trust Fund for Africa, unveiled in 2015, has supported more than 250 programs totaling nearly 5 billion euros across 26 countries, but has had only partial success addressing the underlying drivers of migration, as this article explains.
Large numbers of well-educated Iranians have left their country of birth since its 1979 revolution, in a “brain drain” that has held back Iran’s economy and cultural institutions. Iran’s isolation from the world has worsened in recent years, and a stuttering economy, currency freefall, and widespread impacts of the COVID-19 pandemic have contributed to the underlying factors encouraging emigration, as this article examines.
The European Union’s landmark 2016 migration deal with Turkey offered aid and other benefits in exchange for Turkey's assistance in helping reduce arrivals of asylum seekers and other migrants. At its fifth anniversary, the EU-Turkey deal remains one criticized by human-rights advocates and has met frustration from Turkey, but in many ways created a blueprint for other externalization arrangements, as this article outlines.
Across North America and Europe, immigrants rely on public transit at higher rates than the native born. This article explores why migrants are disproportionately more likely to use public transportation, the role these systems play in immigrant integration, and the impact of the COVID-19 pandemic on commuter trips, budgets, and services.

Frustrated by an uptick in migrant apprehensions at the U.S.-Mexico border in recent months, the Trump administration unveiled a set of sweeping changes, aiming to prosecute for federal immigration crimes every migrant apprehended crossing illegally. The policy will likely be hindered by legal challenges and capacity limitations, as this article explores.
Seizing on reports of a migrant “caravan” making its way northward through Mexico, President Donald Trump called for up to 4,000 National Guard troops to deploy to the Southern border. Although previous presidents took similar action in response to upticks in violence and apprehensions, the picture at the border today differs on several metrics. This article examines how the deployment compares to those under Presidents George W. Bush and Barack Obama.
While much attention has focused on President Trump's efforts to crack down on illegal immigration, the administration has moved, via a much wider scope of actions, to reduce legal immigration to the United States. This article explores changes including slowed processing of family- and employment-based visas, dramatic cuts in refugee admissions, and heightened vetting and evidence requirements for would-be immigrants.
The Trump administration has been steadily building a case to penalize "sanctuary" cities—those jurisdictions that in some way limit their cooperation with federal immigration authorities—after threatening to cut federal funding. Despite court rulings that seemed to strike a blow against these efforts, the Justice Department is moving forward with its strategy, relying on a broad interpretation of a federal statute, as this article explores.
An unannounced sweep of 98 convenience stores by U.S. immigration authorities—resulting in the arrest of 21 unauthorized workers—may signal a new approach to worksite enforcement under the Trump administration, moving away from a strategy of paper-based audits that resulted in higher employer fines and fewer worker arrests. This article explores worksite enforcement over recent decades.
