Presentation Transcript

  1. Data archive in developing countries: preservation and dissemination of microdata as an instrument for better development results Olivier Dupriez Senior Economist / Statistician The World Bank odupriez@worldbank.org

  2. About the World Bank • Mandate: Millennium Development Goals • International Development Agency (IDA): Loans and grants to 81 poorest countries, to support poverty reduction strategies (> $10 Bn per year) • IDA14 replenishment (March 2005) • Focus on effectiveness • IDA Results Measurement System (input/outcomes) • Marrakech Action Plan for Statistics • Recommendation: International Household Survey Network

  3. IHSN - Rationale • In developing countries: sample surveys are a key source of data  needed for targeting, designing, monitoring and evaluating projects and policies • Huge efforts to collect data, but issues of quality, timing, comparability, analytical capacity, accessibility by secondary users, and others  data remain under-exploited

  4. IHSN - Mandate IHSN created in September 2004 to: • Coordinate donors’ activities (survey planning) • Harmonize methods, promote standards • Foster better use of data  requires access by secondary users  build a central survey repository  assist countries in preserving, documenting and disseminating microdata (Toolkit + Handbook)

  5. Building a Central Survey Repository • Started as a World Bank internal project. Now an IHSN activity • Custom-made application (WB) • Geographic coverage: developing countries • Scope of collection: HH surveys / censuses / others • > 2300 surveys/censuses listed (May 2005) > 600 datasets available

  6. A web-based database of surveys, searchable by region/country, type of survey, year, etc. Advanced search (by topic) being developed.

  7. Survey Description For each survey, information is provided in four pages: description, content, documentation, and dataset

  8. Authorized users (identified at logon) can download data. Authorizations are granted by survey at individual level or to groups of users (e.g., all World Bank staff) Non-authorized users must first request and obtain access.

  9. www.surveynetwork.org Webservice available. Used by IHSN website, Health Metrics Network/WHO Country Logbook, and others to publicly disseminate metadata.

  10. Survey Repository: Issues Acquisition • Many surveys poorly documented • Much information lost by producers • Datasets not anonymized / properly edited Management • Need a way to assess quality of datasets • Ad-hoc / informal dissemination agreements • Need a more formal collection, acquisition, and dissemination strategy • Limited “search by topic” (no thesaurus) • Users: demanding, not supplying !

  11. Microdata Management ToolkitDocumentation / Dissemination / Preservation • Objective: proper data archive in/by developing countries (in the past, technical assistance focused on data collection; lack of concern for preservation, documentation and dissemination) • Toolkit: a user-friendly package based on best practice and international standards (specialized DDI/DC editor + CD-Builder)

  12. A specialized DDI/DC metadata editor… (custom-branded Nesstar Publisher) … and a CD-ROM / Web Builder CD-ROMs, DVDs Websites  NESSTAR server: on-line analysis For more information on the Toolkit, see presentation by M. Diggory, O. Dupriez, P. Heus, J. Ryssevik (IASSIST 2005, Session E2)

  13. Survey Data Dissemination Toolkit Microdata Management Toolkit Toolkit - Next steps • Translate, document • Roll-out program (training / technical assistance) • Finalize a “Handbook on Microdata Documentation, Dissemination and Preservation” • Legal, ethical, technical and institutional guidelines to assist developing countries in establishing data archive services • Drafted (ICPSR contribution); more contributions needed! • Further development and link to other tools (e.g., Argus, CsPro, DevInfo, others)
