This data presentation classification is based around collecting both ethnic and national group data.
The ethnic group categories are broadly in line with the data presentation for the 2001 Census and enable general comparability with the Censuses of the different countries of the United Kingdom.
There is a national group question that enables users to identify specific groups such as White-Irish, by analysing respondents who classify themselves as 'White' and as 'Irish'. The national categories tested and proposed are:
English
Scottish
Welsh
Irish
British
Other
An example of the ethnic and national group data presentation for England and/or Wales is available here. Standard data presentations for ethnic group only relating to Scotland, Northern Ireland, Great Britain, and the United Kingdom are given here.
