Derived variables: country of birth from census, grouped
From 2001 Census Definitions: 'There are 5 tick-box responses to the country of birth question: one each for the four parts of the UK and one for the Republic of Ireland. Where there is no applicable tick box, people were asked to write in the present name of their country of birth. The written responses are coded using the ONS Geography Classification of Countries. Countries are classified in output according to the geographical position rather than politics. For example, the Canary Islands are classified as North Africa rather than Western Europe even though they belong to Spain.' Hierarchy of geographical classifications
The ONS Geography Classification of Countries is extremely detailed; offered here is a grouped variable for 2001 with just under 50 codes, and a set of variables for the other censuses designed to be compatible with that for 2001.
