"Europe" is probably too varied an entity for figures to be available as a whole. This link
is to the Office for National Statistics' most recent report.
might also be useful links on the topic. Unfortunately I couldn't get either of them to load (annoying Internet Explorer... I'm at work, what can I say), so maybe, maybe not.
(Also, that UK government drive to reduce net migration? Students are the easiest target: crack down on quantities of student visas issued to foreign nationals, and voila, the immigration numbers immediately reduce. Unfortunately this is currently tanking one section of the economy, namely the private adult education college section and its suppliers. Guess whose company is losing business because one of our client colleges is losing business due to the immigration cuts? Bravo, government: do everything necessary to destroy the economy and then, in the face of evidence to the contrary, keep doing it. I'm not bitter or anything, honest...)
