Border Patrol agents apprehended 92,607 migrants at the U.S.-Mexico border in March, the highest monthly total since April 2007. In response to the influx of migrants, U.S. President Donald Trump recently threatened to shut down the border and cut off aid to three Central American nations where many U.S.-bound migrants originate: El Salvador, Guatemala and Honduras. (Trump has since delayed his proposal to shut down the border.)
As the debate over border security continues, here’s a look at how the recent flow of migrants compares with past migration patterns at the southwest border. All data are from U.S. Customs and Border Protection, the federal agency tasked with patrolling the border.
