According to the Berlin-based Deutsches Institut for Wirtschaftsforschung (DIW), the number of people who have migrated from the new member states to the older members can be estimated at 150,000. Of them, over 50,000 arrived in the UK.
The DIW figures are lower than other estimates, including that of the UK government, which claims to have received some 130,000 work permit applications over the past 12 months. DIW explains the discrepancy with methodological differences.
In DIW’s opinion, those EU-15 states that have applied stringent immigration policies to prospective workers from the new member states could be missing out on an influx of much-needed qualified professionals.
