There is a flaw in your logic. A rise in border apprehensions can be for multiple mutually inclusive reasons, only one of them is an influx in total migrants. Other possibilities include more border agents, better patrol equipment and intelligence, stricter border laws, fewer avenues for legal migrations (hence OP). This could even be because of some mundane changes in how these numbers are tallied, categorized, or published between years.
