Mixed is an ethnicity category that has been used by the United Kingdom's Office for National Statistics since the 1991 Census. Colloquially it refers to British citizens or residents whose parents are of two or more different races or ethnic backgrounds. Mixed-race people are the fastest growing ethnic group in the UK and numbered 1.25 million in the 2011 census.
In the 2001 census, 677,177 classified themselves as of mixed race, making up 1.2 percent of the UK population.Office for National Statistics estimates suggest that 956,700 mixed race people were resident in England (as opposed to the whole of the UK) as of mid-2009, compared to 654,000 at mid-2001. As of May 2011, this figure surpassed 1 million. It has been estimated that, by 2020, 1.24 million people in the UK will be of mixed race. Research conducted by the BBC, however, suggests that the mixed race population could already be twice the official estimate figure - up to 2 million.
3.5 percent of all births in England and Wales in 2005 were mixed race babies, with 0.9 percent being Mixed White and Black Caribbean, 0.5 percent White and Black African, 0.8 percent White and Asian, and 1.3 percent any other mixed background.
Mixed-race people are the fastest growing ethnic minority group (defined according to the National Statistics classification) in the UK and, with all mixed categories counted as one sole group, are predicted to be the largest minority group by 2020 (above British Indian).
In England and Wales, the 2001 census included four sub-categories of mixed ethnic combinations: "White and Black Caribbean", "Mixed White and Black African", "Mixed White and Asian" and "Any other Mixed background", with the latter allowing people to write in their ethnicity. Analysis of census results shows that, in England and Wales only, 237,000 people stated their ethnicity as Mixed White and Black Caribbean, 189,000 as Mixed White and Asian, 156,000 as Other Mixed, and 79,000 Mixed White and Black African.
The estimates for mid-2009 for England only suggest that there are 301,300 people in the Mixed White and Black Caribbean category, 127,500 Mixed White and Black African, 292,400 Mixed White and Asian, and 235,500 Other Mixed. The White and Black African group grew fastest in percentage terms from 2001 to 2009, followed by White and Asian, Other Mixed and then White and Black Caribbean.
The 2011 Census for England and Wales suggested that compared with 2001, the proportion of the population describing themselves as "White and Black Caribbean" rose from 0.5% to 0.8%, "White and Asian" from 0.4% to 0.6%, "White and Black African" from 0.2% to 0.3% and "Other Mixed" 0.3% to 0.5%.
