At the time of the 2001 Census, 7,631 Romanian-born people were residing in the UK.[1] When Romania joined the European Union in January 2007, the British government placed transitional restrictions on the rights of Romanians to move to the UK, which were subsequently extended and currently remain in place.[2] The Office for National Statistics estimates that, in 2012, 101,000 Romanian-born people were resident in the UK.
