The information requested falls within the responsibility of the National Statistician, who has been asked to reply.
Letter from Karen Dunnell, dated 31 January 2007:
As National Statistician I have been asked to reply to your recent question how many and what percentage of the population in each constituency of the UK are first generation Irish people, broken down by region and listed in descending order of percentage. (112095)
As there is no standard ONS definition of “first generation Irish” we have prepared figures for those people whose Country of Birth was Northern Ireland, the Republic of Ireland or Ireland part not stated but whose usual residence was in England, Wales or Scotland. The figures have been broken down by Government Office Region.
The figures have been extracted from Country of Birth Table KS05 on the CD Supplement to the Key Statistics for Parliamentary Constituencies, which is available in the House of Commons Library. For convenience the resulting extract has also been lodged in the House of Commons Library.
