Outline

� Background

� Principles of the revision of Regulation 831/2002

�


� Perspective opened by the revision of Regulation 831/2002

� Discussion - feedback

Background – EU statistics

� Harmonising MSs data collection establishing minimum common standards for EU statistics

� MSs collect data from data provider (individual-household, establishments)

� Eurostat gathering (micro) data from MSs and compiling and


� Eurostat gathering (micro) data from MSs and compiling and disseminating European indicators

� No further redistribution of raw (confidential) data except for scientific purpose but MSs should agree explicitly on each research proposal

� Provision of micro data for research purpose included in the core mission of the ESS– Maximise use of existing data – return on public investment– Value added of scientific research for policy analysis and for

quality of data

Background – Statistical confidentiality

� Ensure the right for confidentiality of information provider (individual, household – establishment)

� Impact on trust of information provider, non response and quality of information collected

� Risk of unlawful disclosure: reputation, business


� Risk of unlawful disclosure: reputation, business continuity, major loss for the EU

� Principles beard in European Regulations: – Regulation 223/2009 on European Statistics– Regulation 831/2001 defining rules and conditions for

access for scientific purpose

Background – ESS governance of statistical confidentiality

� European Statistical System Committee (ESSC –Chief Statistician in NSIs)

� Working Group on Statistical Confidentiality (WGSC


- MS delegates)� TF advising Eurostat for the drafting of the new

regulation – BE, BG, DE, FR, IT, LV, LU, HU, NL, SI, SE, UK

� Role of European Statistics Advisory Committee

The revision of regulation 831/2022 : the process

� 2010: Definition of the principles and strategic orientations of the new Regulation – TF, WGSC

� Feb 2011: Approval of the strategic orientations by ESS Committee – identification of remaining barriers


Committee – identification of remaining barriers � 2011: Drafting the legal text and accompanying procedures –

consultations� 2012: Adoption and entry into force

The revision of regulation 831/2001 : research community consultation

� Draw on a tradition of cooperation with research community (workshops, conferences, research projects)

� Advised by ESAC (J Leshke, L. Kabat, D Livesey)� Close link with the future Data without Boundary FP7

infrastructure research project (CESSDA network of data


infrastructure research project (CESSDA network of data archives)

� Why important at this stage– Trade off will have to be found to obtain a consensus among MS– Importance to be back up by Scientific Community for some

strategic choices

� Warning : no commitment possible at this stage of the process

The revision of regulation 831/2002 : principles

� Regulation is an enabling factor : should allow stepwise development of access in the next decade

� Regulation aims to provide minimum requirements regarding data access (what, how, to whom)


access (what, how, to whom)

� More transparency of procedures

� Objective: widen access to confidential data for scientific purpose– Through a multi mode approach– Involving different partners (DA, NSIs …)– Simplifiying rules, reducig administrative burden where possible

Strategic orientations of the new Regulation

� Introduction of the risk management approach for the release of confidential data: – safe people, safe settings and safe data principle, – Proportionality of control procedures

� Opening new modes of access to micro data, mainly


� Opening new modes of access to micro data, mainly remote access,

� Fostering of the decentralised access to confidential data

� Fostering partnership/delegation of tasks in the provision of access

� Streamlining the procedures for the release of low confidentiality impact level datasets (anonymised files)

Safe data principle : current

� Anonymised data (risk avoidance) release on CD-ROM under contract by Eurostat ( at risk of saturation)

–From 1.04.2011 Eurostat decided not to charge anymore the


–From 1.04.2011 Eurostat decided not to charge anymore the release of CD-ROM–Limited capacity to grow

� Detailed (raw) micro data available in Luxembourg safe centre – very few access requests

Safe data principle : target

� Datasets categorised into three categories taking into account – reidentification risk – perceived impact on the individuals concerned (sensitivity) – perceived impact on the ESS in case of unlawful disclosure of

confidential data


� The 3 confidentiality impact levels (CIL):

1. Low (less sensitive, anonymised files through information coarsening on key variables, outliers/population unique masking or perturbation)

2. Medium (more sensitive data, mode details in key variables) 3. High (raw data received from MS – no direct identifiers – full

information)

Safe data principle

� Procedures to be put in place should be proportionate to the risk and impact

� Low confidentiality impact level datasets released under simplified and timely procedures at zero cost


simplified and timely procedures at zero cost

� Besides confidential data channels : – Public Use Files (early 2012) – Online access (tables) (feasibility and pilot in 2011)– possibly remote execution (submission of batch)

Safe people principle : current

� European universities and research centres

� Lenghtly ( > 12 months) legislative procedure for accreditation other bodies (outside EU universities, Commission DG, …) –


other bodies (outside EU universities, Commission DG, …) –list published in the official journal

� Contract with research institution for each research proposal naming researchers

Safe people principle : target

� More focus on research proposal and principal researchers– Use and need for micro data– Publication provision and public benefit– Experience and professionalism of principal researcher– SDC literacy of principal researcher


� Institutional context will be integrated in screening procedure as a factor of risk – level will depend on type of access/data type – mission and organisation and purpose of research activities– measure in place for physical protection of data (only in case of

transmission of data)

Safe people principle

� Contract/license remains the basis for accountability of the researcher and for eventual sanctions (penal and administrative)

– Simplified procedure for low confidentiality impact level transmission :


transmission : • Framework contract • Automation of consultation of MS• Bilateral agreements with MS to wave out consultation on

specific datasets

Safe settings principle: current

� Transmission (off site) of anonymised files to admissible institutions

� Access in Eurostat safe centre (on site)


� Access in Eurostat safe centre (on site)

Safe settings principle : target

� Various modes of access – On-site – CIL3 – Remote access – CIL 2 ..– Off-site – CIL 1 ..


� Decentralised infrastructure – On site : accreditation of NSI safe centres– Accreditation of data archives and other partners

� Accreditation of access facilities agreed by the ESSC on a case by case basis according to criteria specified beforehand.

Main barriers

� Accreditation of non ESS bodies� Articulation with national law� The concept and implementation of confidentiality

impact level to be operationalised


impact level to be operationalised� Need to keep organisation signing the contract� Defining procedures and criteria for implementing the

regulation

Next steps

� Consultations with NSIs

� Discussion at the meeting of the WGSC in June 2011


� Discussion at the meeting of the ESSC in September 2011

� Voting: November 2011
