With U.S. Customs and Border Protection (CBP) releasing new data last night, we now know what migration at the U.S.-Mexico border looked like through August.
The most notable thing about these charts is the rapid increase in migrant arrivals from June to August, in the areas between ports of entry (official border crossings) where Border Patrol operates. We know that the increase is continuing in September.
June was the first full month after May 11, 2023, when the Title 42 pandemic expulsions policy ended. At that moment, many migrants and smugglers refrained from crossing between ports of entry because it wasn’t clear what would happen next, and migration plummeted to levels not seen since February 2021.
As they grew frustrated with clogged “legal pathways” like the CBP One smartphone app, and as they got better information about the likelihood of being able to pursue asylum claims within the United States despite the Biden administration’s harsh new asylum rule, more have been crossing between the official ports of entry and turning themselves in to Border Patrol agents.
This chart shows, by country, who has been ending up in Border Patrol custody after crossing between ports of entry.
This chart shows, by country, who was able to present themselves at a U.S.-Mexico border port of entry. Of the 51,913 people shown here in August, 87 percent (45,400) had made appointments using CBP One, according to CBP.
The following charts combine people at and between ports of entry (CBP plus Border Patrol). Here are migrants arriving as members of family units (parents plus children). Border Patrol encountered more migrants arriving as families in August 2023 (93,108) than in any month in history. The second-place month (84,486) was May 2019, when Donald Trump was president.
This chart, combining people at and between ports of entry, shows the countries of origin of migrants arriving as unaccompanied minors. August was the number-12 month ever for Border Patrol apprehensions of unaccompanied migrant children: 13,549 last month.
And here are single adult migrants. It was an unremarkable month for single adults (28th place for Border Patrol apprehensions, 74,402, since October 2011, which is the first month for which I have Border Patrol breakdowns by demographic group.)
Finally, this chart combines all migrants at the U.S.-Mexico border: those at and between ports of entry, single adults, families, and children.
