A political crisis marked by Nicaraguan President Daniel Ortega’s growing authoritarianism has sparked the largest emigration in the country’s modern history.

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.

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.

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.

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.
