Which seems... Ridiculous. It provides "border security" in the way TSA provides airport security: By showing theater to make certain folks feel better. As far as the number of people: Flights have record of who is on them, and generally require a passport for international travel (even though there are open borders between EU countries). I've not taken a train internationally, but I'd imagine something similar exists there - or can exist, anyway. It doesn't really cover folks driving (Which would make their numbers different), but I suppose there are less routes into the UK by car.
