Mexicans, however, remain the largest origin group in the country, accounting for 28 percent of all immigrants.

Europe's defining challenge in 2015 was the exponential growth in the number of asylum seekers and migrants arriving on its shores. The European Union and its Member States were slow to respond, and reactive when they did. As trust among Member States and between national and EU-level authorities began to erode, the European Union has found its ability to implement a comprehensive response severely handicapped.

Policy Briefs

In recent years, questions of whether, when, and how to return failed asylum seekers and other migrants to their origin countries have dominated migration debates in many countries. These issues were also taken up in the negotiation of the Global Compact for Safe, Orderly, and Regular Migration, moving the discussion beyond the typical bilateral one. This policy brief outlines how states might more constructively work together on returns and reintegration programs.

In the face of an uptick in unauthorized arrivals in Italy from Tunisia in 2017, the European Union dusted off earlier policy proposals such as funding to increase Tunisia’s border-control capabilities and the creation of disembarkation platforms. This article explores why contemporary developments, including a fragile Tunisian political system, suggest the need for a different approach.

For decades, Mexicans have been the largest immigrant group in the United States. While this is still the case, the Mexican immigrant population is no longer growing at the rate it once was. In fact, between 2010 and 2017, the number of Mexicans in the country first leveled off and then began to decline. This article explores the latest data on Mexican immigrants in the United States.

The United States has a long tradition of providing asylum to those in need. But in recent years, case backlogs have grown and many asylum seekers now wait years for a decision. This report examines the factors that have brought the U.S. asylum system to this crisis point and proposes common-sense steps that can be taken to restore timeliness and fairness, while deterring abuses.

As the Trump administration moves to be able to indefinitely detain parents and children intercepted at the U.S.-Mexico border, whether illegal border crossers or asylum seekers, recent apprehension trends and history suggest hardline policies might not be a slam-dunk deterrent with a Central American population often driven by the desire to escape gang or other violence, as this Policy Beat explores.

Commentaries
September 2018

In a commentary, MPI and Penn State researchers explain why an academic article suggesting the unauthorized population is significantly higher than previously estimated derives from seriously flawed assumptions. The researchers, who peer-reviewed the analysis, find the authors overestimate successful illegal crossings by misapplying data from the 2000s to the 1990s, when crossing patterns were much different.
