The information requested falls within the responsibility of the UK Statistics Authority. I have asked the authority to reply.
Letter from Karen Dunnell, dated 14 May 2008:
As National Statistician, I have been asked to reply to your Parliamentary Question about how many households will be surveyed by the Integrated Household Survey in each year once the survey is fully implemented. (204887)
The Integrated Household Survey (IHS) is being implemented in a phased way, with four of the initial five component surveys already within the IHS. These are the General Household Survey, Expenditure and Food Survey, Omnibus and the English Housing Survey. The fifth survey, the Labour Force Survey, will join the IHS in 2009. At that point, approximately 200,000 individual households will be interviewed in the IHS annually, split across the five IHS survey modules.
From 2009, other new social surveys that start up may also become part of the IHS.
