The information requested falls within the responsibility of the National Statistician, who has been asked to reply.
Letter from Karen Dunnell, National Statistician, dated 14 March 2007.
As National Statistician, I have been asked to reply to your recent Parliamentary Question asking for an estimate of the proportions of Sunni and Shia Muslims respectively who are ordinarily resident in the United Kingdom. [HL2454]
The information requested is not available.
The number of persons who gave their religion as Muslim in the 2001 census in Great Britain was 1,588,890. Figures are not available for Northern Ireland because a separate tick-box for Muslims was not included on its version of the 2001 census form.
