Passage: Academics have argued that the ethnicity categories employed in British national statistics, which were first introduced in the 1991 census, involve confusion between the concepts of ethnicity and race. In 2011, 87.2 per cent of the UK population identified themselves as white, meaning 12.8 per cent of the UK population identify themselves as of one of number of ethnic minority groups. In the 2001 census, this figure was 7.9 per cent of the UK population.Because of differences in the wording of the census forms used in England and Wales, Scotland and Northern Ireland, data on the Other White group is not available for the UK as a whole, but in England and Wales this was the fastest growing group between the 2001 and 2011 censuses, increasing by 1.1 million (1.8 percentage points). Amongst groups for which comparable data is available for all parts of the UK level, the Other Asian category increased from 0.4 per cent to 1.4 per cent of the population between 2001 and 2011, while the Mixed category rose from 1.2 per cent to 2 per cent.Ethnic diversity varies significantly across the UK. 30.4 per centof London's population and 37.4 per cent of Leicester's was estimated to be non-white in 2005, whereas less than 5 per cent of the populations of North East England, Wales and the South West were from ethnic minorities, according to the 2001 census. In 2016, 31.4 per cent of primary and 27.9 per cent of secondary pupils at state schools in England were members of an ethnic minority. The 1991 census was the first UK census to have a question on ethnic group. In the 1991 UK census 94.1 per cent of people reported themselves as being White British, White Irish or White Other with 5.9 per cent of people reporting themselves as coming from other minority groups
