          What is EU-SILC?
• European Union – Statistics on Income and
  Living Conditions
• EU member states, Iceland and Norway
• In Czech republic from 2005
• Annual data on income distribution and social
  inclusion
      • Cross-sectional data
      • Longitudinal data

                                                  www.czso.cz
   Legal framework of EU-SILC
• EU-SILC is based on a common framework:
     • harmonised list of target variables
     • common guidelines
     • common concepts
     • using the same classifications of
       occupation and education
• Revision of legal framework of EU-SILC
  planned 2011

   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

                                       www.czso.cz
         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
