Clearly, something is going on beyond seasonality (it is true that migration tends to pick up in the spring and then fall off in the summer).
Steve Camarota of the Center for Immigration Studies has been crunching the numbers from Customs and Border Protection.
Per his analysis, there were more than twice as many unaccompanied minors apprehended in January of this year (5,694) than in January 2020 (2,680), prior to the pandemic.
In February, the number of unaccompanied minors, more than 9,000, was higher than it had been in any month since May 2019, when there was a widely acknowledged crisis at the border.
In February of this year, more family units were apprehended at the border, nearly 19,000, than in any month since August 2019.
