The term British Mixed has no official definition and is not used by the UK government. Colloqually it refers to British citizens whose parents are of different races, and to the offspring of such people. Mixed Race is included as an ethnic classification on the UK Census.
People of mixed race made up 1.2% of the UK population as of the 2001 census or 677,117 people. The most common mixed race group is White/Black Caribbean with 266,300 people, followed by White/Asian at 189,000 people and then White/Black African with 101,400 people. In British society and media, the term `Mixed-Race' has often been used synonymously with people of primarily the Black and White mix due to this being the largest category and often most visibly identifiable as being mixed.
The mixed race population has a younger age profile than any other minority ethnic group in Britain, where 50% is under 16 years of age. By the year 2020, mixed race Britons are expected to have outnumbered British Indians (currently more than 1 million members), to become the largest ethnic minority in Britain with 1.24 million members, showing a 50% increase in the mixed race population in a decade to come.
