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.
