1 1 OECD Conference: Assessing the Feasibility of Micro-Data Access Micro-Data Access Questionnaire: Synthesis Luxembourg, October 2006 Nadim Ahmad, Statistics Directorate, OECD

2 2 Background - Questionnaire Sent 30 June, seeking views on feasibility options Snap shot indicators Longitudinal indicators Bilateral projects Remote Access Transmission of micro-data –(5(i)) – Accessing private data sets 26 OECD and 2 NM countries

3 3 Synthesis – Current Practice Most countries provide access to some micro-data Typically public-use files With anonymised micro-data available at on-site Research Centres A few countries (e.g. Aus, Dnk, NLD, Swe, Bra) currently have remote access facilities but the mechanisms and data need further investigation and others are investigating their potential (recognising constraints posed by on-site access)

4 4 Synthesis – Social versus Economic Typically, accessible data is social rather than economic But, in most countries, the legal conditions governing access are, de facto, the same for both social and economic data. Difference reflects greater difficulty in preserving confidentiality in economic data sets. Indeed, small countries highlighted their particular difficulties with economic data distributions.

5 5 Synthesis - Trust and Educated Users But many countries have been able to overcome disclosure problems by creating an educated and trusted user network, supported by penalties. And, in practice, this works. No known breaches.

6 6 Synthesis – Non-Residents Some countries cited difficulty in providing access to non-residents who would not be able to be penalised. But other countries have made access available to non-residents and this works. In practice the threat of having accessed removed appears to be the most preventative penalty (for the OECD a removal of access would be catastrophic in terms of reputation and current and future research projects)

7 7 Synthesis – Country Views Many countries viewed remote access as a feasible option, but one that could not be implemented in the short-term due to technical (and not legal) constraints. Most countries welcomed the development of new indicators that provided additional information with no increased risk of confidentiality breaches but the scope of longitudinal indicators is limited by coverage of longitudinal datasets.

8 8 Synthesis – Country Views Access to on-site research data centres and bilateral projects is feasible in most countries - however, from an OECD perspective, such an approach would involve considerable organisational costs and, so, would seem impractical. A number of countries indicated that public-use files, in particular, could be made available to an OECD Centre.

9 9 Synthesis – Summary Tentative conclusions suggest a two stage approach Stage 1: For the OECD to develop with NSOs and analysts a list of indicators that could be produced without compromising confidentiality. E.g. for business statistics providing information relating to distributions, variances, co-variances, and possibly standard regression coefficients.

10 10 Synthesis – Summary Stage 2: To begin to develop remote access options with countries that have facilities available and examine how these could be replicated in other countries over the medium to longer term: examining, in particular, and automated systems. A key deliverable being the development of confidentiality rules and common metadata sets. Pre-requisites would be: Governance Rules for OECD access and OECD user-education program.
