There has been significant public interest in Bulgarian and Romanian migration to the UK in recent months due to changes to immigration restrictions.
Bulgaria and Romania joined the European Union (EU) on 1 January 2007. Since then, migrants from Bulgaria and Romania coming to the UK were subject to transitional employment restrictions, which placed limits on the kind of employment they could undertake. These restrictions ended on 1 January 2014.
There are several sources of official data which could be used to indicate the nature of any impact these changes have had on the level of migration from Bulgaria and Romania to the UK. Some of these data will only include certain groups of migrants, such as those coming to the UK for work. These data will become available at different times.
What data will be available and when?
Employment levels by country of birth and nationality will show the number of Bulgarian and Romanian-born people and Bulgarian and Romanian nationals in employment in the UK. They may have arrived recently and taken up employment immediately, or come to the UK in the past and only recently taken up employment. Estimates for January to March 2014 will be published on 14 May 2014.
Allocations of National Insurance numbers (NINo) to adult overseas nationals show the number of non-British nationals who have been allocated a NINo in a given time period. It is important to note that people may not be allocated a NINo during the same quarter in which they immigrate to the UK. These data will also include people who stay in the UK for less than one year. Estimates for January to March 2014 will be published on 22 May 2014.
International Passenger Survey (IPS) statistics estimate the number of long-term migrants entering and leaving the UK during a given period. A long-term migrant is defined as someone changing their country of usual residence for a period of at least one year. Estimates for the year ending March 2014 will be published on 28 August 2014.
Population by country of birth and nationality data show how many of the usually resident population of the UK were born outside the UK and how many are non-British nationals. It is important to note that these figures do not include people living in communal establishments, such as university halls of residence. Estimates for 2014 will be published in August 2015.
