Re the post from John from Kemsing saying that the UK census lumps us all together. There isn't actually a single UK census. We have different census questionnaires. The 2011 Scottish one in the Country of Birth section asks for country of birth and gives tick boxes for Scotland, England, Wales, Northern Ireland and also the Republic of Ireland plus there is space to fill in freehand if it is somewhere else. Likewise in the National Identity Section it gives tick boxes for Scottish, English, Northern Irish, Welsh or British (tick all that apply) plus space for freehand if somewhere else. Then in the ethnicity section it enables you to break these down further into "white Scottish etc etc etc" or "Asian Scottish etc etc etc"
