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.
