The U.S. Border Patrol reported more than 1.6 million encounters with migrants along the U.S.-Mexico border in the 2021 fiscal year, more than quadruple the number of the prior fiscal year and the highest annual total on record.

While Mexico was the most-common origin country for migrants, a record number of encounters, more than 1 million, involved people from countries other than Mexico. And many involved migrants from some countries that have not historically been common sources of migration at the U.S.-Mexico border, including stark increases in people coming from Brazil, Haiti, and Cuba.
