3.3 SUPPORTING MATERIAL
SUPPORTING MATERIAL
Other material is available to assist clients in analysing the data from the survey. This includes:
- a representation of the computer assisted interview questionnaires used in the HES and SIH, and a copy of the diaries placed with respondents to the HES, which can be downloaded as separate pdf files from the "Details" tab of the website entry for this publication.
- the Household Expenditure Classification (HEC) which is used to classify the HES expenditure data is presented in Appendix 5. Appendix 5 also contains a concordance between the 2003-04 items and 1998-99 items so that changes in the classification can be readily identified, and information on the collection method used for each item. There were three different collection methods - these were to collect the expenditure data through a computer assisted household interview questionnaire (using a variety of recall periods), to collect it in the paper diary, or to derive it using modelling techniques.
- the HEC coding list, which lists the products included in the detailed HEC codes, is presented in Appendix 6.
