Planned revision of EU-SILC
• Object of the revision is the survey as a whole• target variables (number, usefulness,
definitions, guidelines)• longitudinal x panel type of survey• modules • further harmonisation - common
questionnaire? → closely related to input and output
harmonisation

Input harmonisation• All steps of producing
statistical results are consistently standardized
• Harmonisation of wording and order of• questions• answers

Input harmonisation
• Theme for the planned review:• common questionnaire • harmonised wording of questions and
answers at least in non-income variables
→ Advantages:• Better comparability among countries• Easier for data users

Input harmonisation
→ Disadvantages:• different legal system and system of social
benefits in particular countries – need of special questions
• cultural and social differences among countries
• some questions may be useless in specific conditions of some countries (CZ: pension from individual private plans)

Output harmonisation
• Harmonisation where the activities are limited to standardizing the statistical results
• Harmonisation of the product of whole process of creating datasets

Output harmonisation
• EU-SILC ex-ante output harmonisation
(just before the interviewing itself)
→ Advantages:• It leaves space for national specifics –
exact wording and order of questions is not given
• Gives more freedom to solve special problems with obligatory variables

Output harmonisation
→ Disadvantages:• problems with comparability• problem with administrative sources –
discrepancies between this data and data from interviewing
→ underestimation in data from interviews

Other hitches with harmonisation in data producing process
• CAPI x PAPI type of interview• converting one type to another if both are
carried out simultaneously• CAPI - controled in the real time• PAPI - before processing are data
controled only by the interviewer and the guarantee
→ may cause further discrepancies among the data

Conclusion
• Harmonisation: • absolutely necessary for maximal
comparability of data from different countries
• important condition for making outputs on EU as a whole
• Need of a space for member states and their national (cultural and → social) specifics
