1. UNSD/ NSCB Regional workshop on data dissemination & communication Manila, Philippines, 20-22 June 2012 Promoting (survey) microdata dissemination policies: the experience of the IHSN / ADP François Fonteneau, OECD/PARIS21 International Household Survey Network (IHSN) Accelerated Data Program (ADP) francois.fonteneau@oecd.org

2. IHSN / ADP: background Marrakech Action Plan for Statistics (MAPS): creation of IHSN and ADP Program funded by World Bank, implemented by a small core team (P21/WB + others); open partnership (ADB, UNSIAP, SPC, DFID, FAO, others) IHSN: to improve the coordination of intl. organisations’ household survey activities. ADP: to help data producers in developing countries increase the use and value of their survey data.

3. Survey microdata: growing supply, unsatisfied demands By producers: “we don’t know how to deal with microdata” – how to document them? – how to improve transparency on sources? – can we disseminate them in our country? If YES, how to disseminate them? To whom? What costs? “what do others do?” – identification of good practice

4. By users: “we didn’t know they had data” Visibility “they don’t want to share them” Accessibility “these data are messy” Reliability “this is not really what I need” Relevance “how can I assess progress?” Comparability “where is the documentation?” Usability “there is no transparency” Quality, credibility Survey microdata: growing supply, unsatisfied demands

5. Different needs, different challenges Reports, tables (PDF) Indicators On-line interactive tabulation, analysis and mapping tools Microdata (n% sample) and detailed metadata Any web development tool CensusInfo/DevInfo, etc. REDATAM/IMIS, SuperStar, Nesstar, etc. IHSN MMT + NADA No issue of confidentiality Disclosure risk managed by the application Requires data anonymization What outputs?What tools?

6. Promoting microdata dissemination policies: a variety of challenges Legalapply the law…or change it Strategicset your priorities (NSDS) Organizationalbreak silos Financialallocate minimal budget Technicalsteal good practice … and cultural (fear of change) => Advocacy on benefits / risks

7. For discovering data – You and your users will know about data availability by providing searchable data catalogs For making data usable – Users need to fully understand the data: why, by whom, when, and how they were collected, processed and disseminated For assessing data quality => International metadata standards for microdata: DDI The importance of documentation

8. DDI : before and after (...or worse !)

9. GSBPM

10. GSBPM, DDI, SDMX

11. IHSN Microdata Management Toolkit (DDI metadata editor) NADA: on line searchable survey cataloguing system IHSN toolkit for documentation

12. Anonymized datasets for dissemination – Anonymization techniques/tools: Risk measurement / risk reduction / information loss Methods: recoding, rank swapping, micro-aggregation, sampling, etc. Available tool (R package): sdcMicro {guidelines in preparation}sdcMicro – Different levels of anonymization / different users controls / different procedures : PUF; SUF Full dataset in enclave  direct control of NSO Confidentiality of microdata

13. Only when no confidentiality concerns 3 modes for file distribution: – PUF - Direct – SUF - Licensed – Enclave Screen users and usage Progressive approach

14. From UNECE Task Force 1.It is appropriate for microdata collected for official statistical purposes to be used for statistical analysis to support research as long as confidentiality is protected (i.e. as long as it is not possible to identify data referring to an individual). 2.Microdata should only be made available for statistical purposes. 3.Provision of microdata should be consistent with legal and other necessary arrangements that ensure that confidentiality of the released microdata is protected. 4.The procedures for researcher access to microdata, as well as the uses and users of microdata should be transparent, and publicly available.
