Two men talk during a retiree luncheon

Results from the 2020 census show that the U.S. population has been growing at its slowest rate since the Great Depression. Reduced immigration has been one component of this sluggish population growth, which could pose a problem for the United States as people age and strain public retirement systems. This U.S. Policy Beat article examines how immigration fits into the country's demographic puzzle.

President Joe Biden speaks to journalists at the White House.

During his first 100 days in office, U.S. President Joe Biden took more than three times as many executive actions on immigration as predecessor Donald Trump. While rising encounters at the U.S.-Mexico border have captured major attention, Biden has been remarkably active in areas that have received far less attention, including interior enforcement. This article explores the administration's actions during its first three months.

Migrants arrive in Greece on a crowded boat from Turkey.

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.

Unaccompanied minors undergo processing at a temporary facility in Texas.

The number of unaccompanied child migrants at the U.S. southern border has risen, presenting President Joe Biden with challenges similar to those faced by his predecessors in 2014 and 2019. This article examines the previous episodes and evaluates how Biden is mirroring or deviating from previous presidents' responses.

President Joe Biden signs executive orders on immigration in the White House.

President Joe Biden has grand ambitions to reshape the U.S. immigration system, but his administration has run into early stumbling blocks in rolling back the strict enforcement regime of his predecessor. Administrative resistance, a tangled web of legal agreements signed by the Trump administration, and anxieties about a possible uptick in immigrants and asylum seekers at the border have posed early challenges to Biden’s agenda.

While Donald Trump’s presidency is perceived as being the most active on immigration, touching nearly every aspect of the U.S. immigration system, President Joe Biden’s administration has far outpaced his predecessor in the number of executive actions taken during his first year in office—even as the pace of change has gone largely unnoticed, as this article explores.

The European push to increase migrant returns has led to new investments in assisted voluntary return and reintegration (AVRR) programs. Yet it is hard to tell whether these investments are paying off. This report explores what is and is not known about returnee reintegration, and how improved monitoring and evaluation would help bridge knowledge gaps and inform future decisions about programming, funding, and strategy.

As host to more immigrants than any other country, the United States has been shaped and reshaped by immigration over the centuries, with the issue at times becoming a flashpoint. This article covers the history of U.S. immigration and the major laws governing immigration, and provides a comprehensive overview of the present-day immigrant population.

The Biden administration's court-ordered restart of the controversial Migrant Protection Protocols, known informally as the Remain in Mexico policy, puts it in the awkward position of reviving a program it is simultaneously still trying to end. The Trump-era program forced tens of thousands of migrants to wait out the duration of their U.S. immigration court hearings in Mexico and was only questionably successful at deterring unauthorized arrivals.
