Access to anonymised microdata sets

Release of anonymised microdata sets as a data access channel

In the context of release of anonymised microdata sets the HCSO sends microdata sets to researchers requesting the dataset, based on a contract.


Microdata sets are datasets that contain information on observation units. Microdata sets in their original form allow the identification and the disclosure of information on observation units. Anonymised microdata sets are the form microdata that have been modified by statistical disclosure control methods in order to reduce to an acceptable level, in accordance with current best practices, the disclosure risk of statistical units to which they relate. With anonymised microdata sets the link between the information presented in the dataset and the data providers cannot be reestablished therefore these datasets can be released to researchers, given that adequate legal protection measures are in place.


Anonymised microdata sets are always released with accompanying methodological documentation, describing the methodology used during anonymisation and their effects on the dataset.


Who can use anonymised microdata sets?

Release of anonymised microdata sets is available only for scientific purposes and access is granted only for approved research projects that meet all researcher accreditation criteria.


In case of research with no institutional background, the HCSO provides access for scientific purposes only in safe environment therefore in this case Safe Centre access, remote access and remote execution data access channels are available.


Datasets available as anonymised microdata sets

In the context of release of anonymised microdata sets all datasets managed by the HCSO can be requested. Following the receival of the data request, the HCSO fully examines if it can be fulfilled from professional point of view.


Process of releasing anonymised microdata sets

In order to approve the release of anonymised microdata sets for the given data request, the HCSO undertakes a researcher accreditation procedure and investigates the content of the request from professional and data protection point of view.


  • Initiating release of anonymised microdata sets

Release of anonymised microdata sets can be requested by the completion of the data request form for access to anonymised microdata sets and its transmission to the HCSO via info@ksh.hu. The HCSO will request the completion of the data request form if the request is not forwarded to the HCSO using the above linked standard form.

  • Evaluation of request for release of anonymised microdata sets

Following the transmission of the data request form for access to anonymised microdata sets , the HCSO carries out researcher accreditation. Following the accreditation procedure the HCSO evaluates the data request if it can be fulfilled both from professional and data protection point of view. If additional consultation is necessary during the evaluation, the HCSO will contact the person sent the data request.


  • Signing contract and confidentiality commitment

Contract and confidentiality commitments are to be signed for data requests successfully approved after researcher accreditation and evaluation of the request form from professional and data protection point of view. The contract sets the rights and obligations of the entity requesting the dataset and the HCSO within the frame of the concerned research project. Sample of the standard templates for the contract and the confidentiality commitment are available here:

  • Release of anonymised microdata sets

Following the signing of the contract and the confidentiality commitment and after the payment of the fee – if any –, the HCSO releases the anonymised microdata sets to the researcher in accordance with the conditions specified in the contract.


Anonymised microdata sets available free of charge and for a fee

In case the requested anonymised microdata set is not available in the form and with the content as requested, the HCSO might charge for the production of the requested dataset.


For the production of such anonymised microdata set 60.000 HUF/day + VAT is to be paid.


Publicity of information on research projects

For approved research proposals for release of anonymised microdata sets, the HCSO publishes the following information on each research project on its website:


  • topic of the research project
  • official full name of the Institution
