Survey design Unit of study: Households, household members 10 - years Household and individual characteristics: A Household questionnaire, face to face interview, information on the household, household composition etc. An Individual questionnaire, interview or left behind to be filled in by household members 10 years or older, information on individuals A Diary, left behind to be filled in by household members 10 years or older for two randomly selected, designated days, a weekday and a weekend day. The diary records five recording domains: primary and secondary activities, ”for whom”, ”with whom” and location/means of transport. A Week diary, records working hours for gainfully employed. Covering a week. A Code system for activities and other information in the diary.
Field process for one household Interview:- Household- Household members Randomly designated diary days Time X X X Interviewer’spreparations Coding, etc
Harmonisation approach Voluntary basis Guidelines recommending uniformity in methods, procedures, forms, concepts and definitions
Pilot surveys in 18 countries, 9 EU, 9 non-EU Data from 12 countries at disposal for evaluation Evaluation approach: a search for possible problems in the survey process and defects in the data
General conclusions Potential threat: Non-response Response problems: Greater impact on household level than individual level Diary data: Few indications on severe problems Exception: the “for whom” query in the diary
Recommendations A shift towards more output and less input harmonisation, i.e. less prescriptive guidelines Non-response: optimise response rates for 1. individuals 2. households Limit respondents’ burden Do not prescribe more than necessary, secure freedom of action
More recommendations General approach: • Specify and agree on - a set of well defined estimates in priority order (basic requirement: random days covering a year) - a set of populations groups - procedures (e.g. completion, timely diary keeping, instructions, rules for postponing, etc) • But: - a common principle diary format (self adm., fixed time intervals) - common activity classification and coding index
