  1. Developments of the Data Infrastructure in Germany since the end of the 90‘s PD Dr. Hilmar Schneider, IZA Bonn ODaF Europe 2009, IZA, Bonn, April 2nd-3rd, 2009

  2. Who are the key players in official micro data production in Germany? • Independent Statistical Offices at the Länder level are collecting data on household and firm level (Micro census, census, income and expenditure survey, cost structure survey, etc.) • Federal Statistical Office, Wiesbaden (co-ordinates statistical offices at the Länder level, but has no directives; however, many official surveys are based on federal law) • Federal Labor Agency, Nürnberg (main source: individual data that are relevant for pension claims; individual data related to job search and active labor market policy) • Federal Reserve Bank of Germany (firm level data and data related to the monetary market)

  3. Philosophy of the Federal Statistical Offices • Providing aggregate figures for relevant issues of the economy and the society • Data collection according to legal duties Consequences • Relevant information is collected independently in different surveys (Example: Hourly wages can only be computed on the aggregate level) • Huge waste of information • Heterogeneity on the micro level cannot be exploited for the identification of causal structures

  4. The situation in the middle of the 90‘s • Access to micro data from official statistics was almost impossible • No interaction between official statistics and the research community • Researchers had to address directly to the administration • Prohibitive cost for access to micro data • Little documentation of available data • Huge concern about the potential of de-anonymization of official micro data

  5. What caused the tipping point at the end of the 90‘s? • Large-scale research project on anonymization of micro data (Hauser/Müller) • As a result, the concept of factual anonymization became accepted • Memorandum by Hauser, Wagner, Zimmermann: Erfolgsbedingungen empirischer Wirtschaftsforschung und empirisch gestützter wirtschafts- und sozialpolitischer Beratung (IZA DP No. 14)

  6. The process triggered by the memorandum • In late 1999, the Federal Minister for Education and Research called a „Commission for the improvement of informational infrastructure between science and statistics“ • In early 2001, the commission published its report („Ways to an improved informational infrastructure“) • The report contained 35 recommendations, among them • Creation of research data centres and data service centres • Creation of public use files from official micro data • Creation of a Council for Social and Economic Data (RatSWD) • In late 2001, the Constituing Council for Social and Economic Data was formed • In 2002, the first research data centres were founded • In late 2004, the Council for Social and Economic Data was constituted

  7. About the RatSWD • 12 members, 6 of them elected every two years by a scientist community (researchers with a doctoral degree), the other 6 are mandated by research data centres and data service centres • Funded by the Federal Ministry of Education and Research • Main objectives: • Advising federal governments with regard to further improvement of data infrastructure • Recommendations regarding the establishment and evaluation of research data centres and data service centres • Stimulating and supporting projects that might contribute to the improvement of data infrastructure • Promotion of scientific offspring • Improving the interrelations between science and official statistics • The RatSWD has been called for six years and is currently undergoing an evaluation of its work

  8. About the RatSWD

  9. The research data centres • Data Research Centre of the Federal Statistical Office • Data Research Centre of the Statistical Offices of the Länder • Data Research Centre of the Federal Labor Agency at the Institute for Employment Research • Data Research Centre of the German Pension Insurance • Data Research Centre at the Institute for Educational Progress

  10. What are the objectives of Research Data Centres? • Provision of available data for scientific research • Compliance with data protection rules • Equal treatment of data users • Creation of user friendly data • Independent research • Avoiding privileged access to micro data

  11. Structural Problems of Research Data Centres • Dependent part of a public authority instead of independent institution • Fuzzy frontier between routine task of authority and special task of RDC • Declarative disposal with regard to external funds needed • After initial funding by the Federal Ministry of Education and Research has run out, internal legitimization is becoming dominant

  12. Synergy Effects • KombiFid (establishment data based on surveys carried out by the Federal Statistical Office, and the Deutsche Bundesbank with establishment data of the Federal Labor Agency) • Merged Biographies (employment status records of the Federal Labor Agency merged with pension records of the German Pension Insurance) • McTax Panel (tax payer panel merged with data from micro census)

  13. The Data Service Centres • IDSC at IZA • German Micro Data Lab at GESIS

  14. What are the objectives of Data Service Centres? • Provision of comparative data documentation (meta data) • Training and advising data users • Development of adequate concepts of anonymization • Development of prototypical scientific use files • Extension of analytical potential of available data sets • Service for data analysis (remote access) • Support for data users • Agency to international micro data sets • Preparation of virtual data library • Development of links across different data sources • Development of indicators • Independent research with focus on methodology • Many more ...

  15. Conflicts between Research Data Centres and Data Service Centres • Competition between RDCs and DSCs in the field of user service, especially with regard to data documentation and remote data access • RDSs are under external pressure by service offered through DSCs • RDCs are trying to make DSCs obsolete by adapting services that were originally provided by DSCs • Danger of losing comprehensive value added (e.g. comparative documentation of data) • RDCs may lose internal power of legitimation, if competitive pressure vanishes

  16. Concluding remarks • The creation of RDCs and DSCs has been a success story • Competition between RDCs and DSCs should rather be understood as a driving force for progress than a redundancy, which absorbes ressources • Unused potential for the creation of DSCs
