There’s No Migrant ‘Surge’ at the U.S. Southern Border. Here’s the Data

Last week, at the U.S. border with Mexico, House Minority Leader Kevin McCarthy (R-Calif.) declared that the recent increase in unaccompanied minors attempting to enter the United States was a “crisis … created by the presidential policies of this new administration.”

We looked at data from U.S. Customs and Border Protection to see whether there’s a “crisis” — or even a “surge,” as many news outlets have characterized it. We analyzed monthly CBP data from 2012 to now and found no crisis or surge that can be attributed to Biden administration policies. Rather, the current increase in apprehensions fits a predictable pattern of seasonal changes in undocumented immigration combined with a backlog of demand because of 2020’s coronavirus border closure.

It’s not a surge. It’s the usual seasonal increase.

The CBP reports monthly data on how many migrants its agents apprehend at the southern border, including unaccompanied minors. The figure below shows the most recent data the CBP has made publicly available.

What we’re seeing, in other words, isn’t a surge or crisis, but a predictable seasonal shift. When the numbers drop again in June and July, policymakers may be tempted to claim that their deterrence policies succeeded. But that will just be the usual seasonal drop.
