It is estimated that in 1950 there were no more than 20,000 non-white residents in the United Kingdom, almost all having been born outside the UK and now mainly residing in England. However, the considerable migration after World War II increased the ethnic and racial diversity of UK, especially in London. The
race relations policies that have been developed broadly reflect the principles of
multiculturalism, although there is no official national commitment to
multiculturalism. The national identity of 'being British' is to respect the laws and parliamentary structures, as well as all maintaining the right to equality; however, this does not cover the concept of multiculturalism. This concept of 'being British' faces criticism on the grounds that it has failed to sufficiently promote
social integration,. Some commentators have questioned the dichotomy between diversity and integration. In 2016, the British government held a
European Union membership referendum. The result of the referendum showed that 51.9% of British voters wanted to leave the EU. On 31 January 2020, the deal was reached for the
United Kingdom of Great Britain and Northern Ireland to leave the EU on 1 January 2021, also known as
Brexit, with terms being agreed to on 24 December 2020. In contrast, Ipsos MORI data from 2008 showed that only 30 per cent saw multiculturalism as making the UK a better place to live, with 38 per cent seeing it as a threat. 41 per cent of respondents to the 2008 poll favoured the development of a shared identity over the celebration of diverse values and cultures, with 27 per cent favouring the latter and 30 per cent undecided. A study conducted for the
Commission for Racial Equality (CRE) in 2005, found that in
England, the majority of ethnic minority participants called themselves British, whereas white English participants said
English first and
British second. In
Wales and
Scotland the majority of white and ethnic minority participants identified with Welsh or Scottish first and British second. Research suggests that on average ethnic minorities are twice as likely to say their ethnicity is important to them than white British participants, although the extent of this difference also interacted with political beliefs. Other research conducted for the CRE found that white participants felt that there was a threat to
Britishness from large-scale immigration, claiming that they perceived ethnic minorities made a rise in
moral pluralism and
political correctness. Much of this frustration was directed at
Muslims rather than minorities in general. Muslim participants in the study reported feeling victimised and stated that they felt the pressure of choosing between Muslim and British identities, whereas they saw it possible to be both. == Political representation ==
