  2. Introduction • Background and context to the IHS • Component surveys of the IHS • Structure of the IHS • Implementation • Future of the IHS

  3. Background and Drivers • Separate continuous household surveys managed by different teams, with different sample and fieldwork designs, and processing systems. • Aim of the IHS is to integrate surveys into one modular survey with a core set of questions and survey modules ‘bolted’ to the core. Drivers • Harmonisation of questions - Some harmonised questions, concepts and outputs where developed across surveys during the 1990’s. But many subtle differences too leading to different competing estimates. • Inter-Censal Data – Pressure to provide more accurate population data between censuses • Demand for Local Level Data - Ever-growing demand for more information, particularly at a local level within the UK • Value for Money - Pressure to deliver better value for money from the ONS household survey programme

  4. Which Continuous Surveys? (Current) The IHS was launched in January 2008 and contained the following surveys: • General Lifestyle Survey – Longitudinal (GLF) – 4 wave panel interview at 12 month intervals • Living Costs & Food (LCF) – single interview. Two week diary-keeping element. • Opinions (OPN) – single interview with one selected adult in household • English Housing Survey (EHS) – single interview + surveyor visit

  5. Which Continuous Surveys? (Future) • Quarterly Labour Force Survey (LFS ) – 5 wave panel interview at 13 week intervals (April 2009) • Annual Population Survey (APS) – 4 wave panel interview at 12 month intervals (April 2009) • Life Opportunities Survey (July 2009)

  7. IHS Core Content Initially, the IHS is based around the existing ONS surveys, plus a set of common core questions collected from each household and adult household member. • Household, family and individual level questions • Fixed core questions (5+ years) • Long Term Goal - Rotating core (questions repeated every few years – subject to demand and funding) Criteria for consideration for inclusion in core: • Classificatory variable essential for analysis • Clear requirement for a high level of precision nationally, regionally or sub-regionally and not provided elsewhere • Information that can be collected either face-to-face or by telephone interview • Proxy responses acceptable, but a preference for face-to-face • Topics which would not adversely affect response to the interview as a whole • Stability of funding over time

  8. Current Design of the Core Survey testing and the Pilot of the IHS identified issues with the original core design: • Need to maintain flow of interviews – original concept would interrupt flow as there would be a need to return to topics later in the questionnaire. • Difficult to move some question from historic position on questionnaire. • Difficult to harmonise some questions and allow modules to continue to supply historic outputs e.g. education questions on the GLF. • The Core was modified so that some topic-specific questions are interwoven with core questions to improve flow, reduce interview length (and also minimises potential for discontinuities in key time series). • Working towards a more harmonised IHS Core.

  9. Current Structure of Core Using GLF as an example Core Module IHS Core GLF Module Original design Current design InterviewLength Core block GLF block

  10. IHS: 2008 & 2009 Sample Size by Component Survey • The expected breakdown of the annual sample by interview types is as follows: * EHS sample is for 8 months only **LFS & APS from April 2009 *** LOS from June 2009

  11. Sample Design • Original plan – all IHS surveys to have an unclustered design • Problems with technology needed to implement a full unclustered design in field • Current plans • LOS, EHS and LFS unclustered • Opinions, LCF and GLF clustered

  12. IHS: Phased Implementation Plan 2010 First IHS Core Data Release

  13. The Future • IHS Output Strategy is currently being developed • First dataset to be released will be in the first half of 2010 and will contain 2009 data. • Produce new rolling annual outputs based on core information across all households • Improve a range of existing survey outputs using two phase weighting • Review some topics to explore options for further harmonisation of content across interview types (e.g. education) to enable cross-interview analyses • Bring in more surveys into the IHS – subject to their suitability for inclusion • Consider wider population coverage (non-private household population)
