The information requested falls within the responsibility of the UK Statistics Authority. I have asked the authority to reply.Letter from Karen Dunnell, dated 9 May 2008:"As National Statistician I have been asked to reply to your recent question asking how many and what proportion of those under the age of (a) three, (b) five and (c) 16 years had been ""bereaved by the death of their (i) mother, (ii) father and (iii) sibling at the latest date for which figures are available. (202856)""Although information on the relationship of the informant to the deceased is collected at death registration, information on whether the deceased had living children or siblings when death occurred is not, and therefore the information requested is not available."
