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.

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.

Our podcast Changing Climate, Changing Migration dives deep into the intersection of climate change and migration to separate fact from fiction.
