The information requested falls within the responsibility of the National Statistician, who has been asked to reply.
Letter from Karen Dunnell, dated 17 July 2007:
As National Statistician, I have been asked to reply to your recent question asking the Chancellor of the Exchequer what proportion of children live in households where the household income is entirely dependent on benefits. (150055).
Statistics on the receipt of benefits are published in the article “The effects of taxes and benefits on household income”. The latest article, for the year 2005-06, was published on the National Statistics website on 17 May 2007 at http://www.statistics.gov.uk/taxesbenefits. This annual analysis is based on data from the Expenditure and Food Survey, which is an annual survey of approximately 7,000 households in the UK.
Based on the same survey results used to produce the annual taxes and benefits article, it has been estimated that 11 per cent. of children in the UK live in households where the household income is entirely dependent on benefits.
