The South American immigrant population in the United States has grown at a faster rate than that of the overall foreign-born population, amid crises in Venezuela, Colombia, and elsewhere. Yet South Americans still account for only about one in ten U.S. immigrants. While they mirror the overall U.S. immigrant population in several demographic characteristics, there are some notable differences, as this article details.
Hong Kong finds itself in the middle of opposing trends. Amid political unrest, Beijing's increasing security pressure, and pandemic disruptions, many Hong Kongers have left and been replaced by a new group of immigrants, largely from mainland China. The dynamic has raised questions whether Hong Kong will remain a global cosmopolitan hub or instead turn inward to Asia, as this article discusses.

Foreign governments play a crucial and yet underappreciated role in migration management, and can either aid or frustrate U.S. border-control aims, as this article explores.

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.

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.
There are 2.7 million Indian immigrants in the United States, making them the second-largest immigrant group after Mexicans. This number has increased dramatically in recent years, growing 13-fold between 1980 and 2019. This article provides an overview of this population, which is more highly educated, more likely to work in management positions, and higher-earning than the U.S. born and overall immigrant population.
Even as the number of people making the dangerous journey through the Central Mediterranean from North Africa to Europe has declined since the migration and refugee crisis of 2015-16, the rate of deaths has increased. This article evaluates the role of Europe's hardening approach to trans-Mediterranean migration and the criminalization of search-and-rescue operations by nongovernmental organizations.

Scholars have declared feminization to be a core dimension of the new age of international migration. This article sketches a more nuanced understanding, noting that an uptick in female migration occurred far earlier. The authors examine global historical patterns of female migration in order to understand the causes and consequences of the migration gender balance, which varies considerably across time, cultures, and nations.
Kenyan migration to the Gulf Cooperation Council (GCC) countries has been on the rise over the last few decades, spurred by rising unemployment and instability in Kenya combined with the GCC region's economic growth and proximity. While both sending and origin countries benefit economically from this new migration, it presents significant challenges for these governments, particularly in the area of labor rights, as this feature article explores.
Against a backdrop of anxieties about migration, the United Kingdom's government set a referendum for June 2016 on whether to withdraw from the European Union. This article explores the role played by migration in the decision to call the referendum, how immigration might influence the result, and finally the implications of both referendum outcomes (Leave and Remain) in terms of migration policy and regulation.
At least 10 million people worldwide are stateless, including 1 million in West Africa, though experts believe the true number may be much higher. West Africa's colonial heritage and nationality laws have increased the risk of statelessness, particularly for vulnerable social groups including migrants and their descendants, refugees, and children. Governments across the region have recently initiated action plans to eradicate statelessness, as this feature explores.
