I haven’t updated this one in a while. Here is a chart of migrants apprehended per Border Patrol agent per year between 1992 and 2022. The data table is here.

With 133 migrants per agent, 2022 saw the largest number since the year 2000. Unlike 2000, though, 35 migrants per agent were unaccompanied children or family unit members, nearly all of whom were trying to be apprehended—no pursuit needed—in order to seek asylum.

The same describes many of the 95 single adults, and of those seeking to avoid capture, many were double-counted because the Title 42 pandemic expulsions policy facilitated repeat attempts to cross. In 2000, nearly all migrants were single adult Mexican citizens who did not request asylum.
