A political crisis marked by Nicaraguan President Daniel Ortega’s growing authoritarianism has sparked the largest emigration in the country’s modern history. Hundreds of thousands have fled, including intellectuals, artists, and academics.

Pandemic-related U.S. policies have led to more than 2.6 million migrant expulsions at the U.S.-Mexico border, expanded public benefits to cover millions more U.S. residents, and offered free COVID-19 vaccines and treatment. Many of these policies are now likely to end as the Biden administration in May 2023 formally declares the pandemic to be over, although what comes next remains unclear.

Venezuelans comprise one of the fastest-growing immigrant groups in the United States, nearly tripling in size from 2010 to 2021. Much of this migration has been fueled by crisis in Venezuela, where political unrest and economic strife have caused millions to flee since 2015, most remaining in Latin America. Venezuelan immigrants are far more likely than the overall foreign- and U.S.-born populations to have a college degree. Take an in-depth look at this immigrant population.
Millions of immigrants fill key sectors in Russia’s economy, help offset its demographic challenges, and support origin communities, particularly in Central Asia. Since Russia's invasion of Ukraine, many have also been pressured into joining the military, and meanwhile face continued marginalization by Russian society.

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.

Despite a widespread perception that the Trump administration has drastically slashed legal immigration to the United States, a review of the data shows that temporary and permanent admissions during the period mostly followed previous trends—at least until the COVID-19 pandemic hit. This article examines trends in temporary, permanent, and humanitarian admissions during the administration, and the related policies that could take a more significant bite ahead if left unchanged.
Climate-induced migration can lead to tensions and violence between host communities and new arrivals. This conflict can flare up at various levels, including among rural farmers and herders in relatively peaceful countries such as Tanzania.
The nearly 11 million Mexican immigrants in the United States represent almost one-quarter of the country’s entire immigrant population, and as such are the largest foreign-born group. But their numbers have been declining, shrinking by 7 percent between 2010 and 2019. Among recently arrived immigrants, those from China and India now outpace Mexicans for the first time.
Before entering office, President Donald Trump promised to deport millions of unauthorized immigrants. Yet despite his general successes in creating a more restrictive and punitive immigration system, this goal has eluded his administration. So-called “sanctuary” policies implemented by state and local governments to limit their cooperation with U.S. Immigration and Customs Enforcement have been a key reason why arrests and removals have not reached earlier peaks.
Climate change is affecting human movement now, causing internal displacement and international migration, and will do so in the future. But the impact is often indirect, and rarely is the process as straightforward as one might think. This article provides an overview of research on how climatic hazards drive and affect migration, reviewing which types of people might migrate and under what conditions.

After receiving more than 2 million asylum seekers in 2015-16, European countries are turning to the task of integrating the newcomers, including getting refugees into work. This article explores labor market integration of refugees in five Northern European countries—Denmark, Germany, the Netherlands, Norway, and Sweden—drawing key lessons for today from the experiences of earlier groups of humanitarian arrivals.
The mental health of asylum seekers has emerged as an important issue following the 2015-16 European migration and refugee crisis. Many asylum seekers suffer from depression, post-traumatic stress disorder, and similar conditions—with implications not only for their well-being but also potentially for the outcomes of their claims and the integrity of the asylum system as a whole, as this article explores.
Chile's immigrant population has more than quadrupled since the country emerged from dictatorship in the early 1990s. As immigration has grown and moved away from its European roots to become more diverse, it has emerged as a hot-button political issue, complicating longstanding efforts to reform the country's 1975 immigration law. This article explores Chile's shift to the right on immigration, and how policies might evolve under the presidency of conservative Sebastián Piñera.
Even as the United States and countries in Europe have made a right turn on immigration in recent years, Canada has remained a largely welcoming country. Underlying this resilience is an approach to immigration focused on active management and refinement of policies as well as long-term economic, social, and political integration, as this article explores.
