I don't havr anny current figures (new one) but it is noticable that we have more emigrants coming back to Poland. Companies get CV's from emigrants in UK. If you are looking for old topics there were somewhere discussions about it.
What is good that people with financial expirience are going back in result of current crisise, this is plus of this unpleasant for us situation.
My sister was rebuilding terrace and was looking for profesionals to do it and there was plenty of guys who had just came back from foreign country - lauborers are coming back too.
