It appears that Mexico's act of good faith to avoid tariffs may have begun to pay off.
According to leaked figures, US Border Patrol apprehensions of illegal immigrants dropped precipitously in June, weeks after Mexico announced the deployment of 15,000 National Guard troops to the US-Mexico border and froze the bank accounts of 26 human traffickers with "probable links with human trafficking and illegal aid to migrant caravans."
According to the preliminary figures, leaked to Axios, there were over 87,000 apprehensions in the month of June, a drop of nearly 35% vs. 132,887 apprehensions in May.
Roughly 7,000 of the apprehensions were unaccompanied minors, 52,000 were family units, and 28,000 (roughly 1/3) were single adults according to the report.
That said, Axios's Alayna Treene says that DHS officials told her border crossings are typically lower in hotter months, and that it would be difficult to gauge whether Mexico's troop deployment or other policies. On the other hand, one look at the above chart provides a clear look at seasonality going back to 2014.
Worth noting: These preliminary figures only capture the number of apprehensions (those who cross illegally) on the southwest border. They do not include the number of inadmissibles (those who migrate through ports of entry), which is normally included in the total migration data U.S. Customs and Border Protection (CBP) releases each month. They are also subject to change given that they're continuously updated by CBP until the final figures are published. -Axios
