Migrant Workers: Romanians and Bulgarians

Answer

The information requested falls within the responsibility of the UK Statistics Authority. I have asked the authority to reply. Letter from Stephen Penneck, Director-General for ONS, to Lord Laird, dated March 2012. As Director-General for the Office for National Statistics, I have been asked to reply to your recent Parliamentary Question, further to the Written Answer by Lord Henley on 5 March (WA 393-4), how many (1) Romanians. and (2) Bulgarians, have migrated to the United Kingdom since those countries joined the European Union on 1 January 2007, according to the International Passenger Survey; and whether the Office for National Statistics uses that figure or the Annual Population Survey figure to calculate net migration into the United Kingdom (HL16437). The International Passenger Survey estimates that (1) 16,000 (SE 26%) Bulgarian citizens and (2) 27,000 (SE 14%) Romanian citizens migrated to the United Kingdom between 1 January 2007 and 31 December 2010. Standard error percentages (SE%) indicate the robustness of each estimate. A migration figure with a standard error percentage greater than 25% is not considered to be reliable for practical purposes. The Office for National Statistics calculates Long-Term International Migration (LTIM) estimates from the International Passenger Survey (IPS), supplemented with data on flows to and from Northern Ireland, adjustments for asylum seekers and for those who change their intentions. Net migration is calculated from LTIM as the difference between the estimates of inflow and outflow, which is largely based on the IPS. The Annual Population Survey is used to calculate estimates of population stocks resident in the United Kingdom and is not used to calculate migration flows.
