In order to fulfill data requests for not public statistical information, the HCSO offers 6 data access channels for the users.

2 of these channels are available for all users without restrictions while 4 of them are available for researchers for scientific purposes only. For data access channels available for scientific purposes only, a researcher accreditation procedure is applicable and a contract and a confidentiality commitment must be signed.

The following 2 data access channels are available for all users without restrictions:
Tabular data (both predefined and customised) and highly anonymised Public Use Files are available to all users with the acceptance of Terms of Use.

Requests for tabular data: Using this data access channel, access to tabular data can be requested. Following the positive evaluation of the data request from professional and data protection point of view, the requested tabular data will be sent to the person requesting the data using the preferred transmission mode (e-mail, post).

Access to Public Use Files: Publicly available microdata sets with strong statistical disclosure control can be accessed by using this data access channel for testing, teaching and research purposes.

Data access channels available for scientific purposes only:
The following 4 data access channels are available only for researchers for scientific purposes. The HCSO performs a researcher accreditation procedure for all data requests for these 4 data access channels. Release of anonymised microdata sets where direct identifiers are removed and further statistical disclosure control methods have been applied, as well as access to deidentified, but more detailed data in the Safe Centre or through remote access or remote execution, are reserved to researchers only.

Safe Centre access: The HCSO offers access to deidentified microdata sets for scientific purposes in the safe environment of the Safe Centre operated by the HCSO in Budapest.

Remote access: This data access channel offers access to deidentified microdata sets for scientific purposes in the safe environment of the remote access points operated by the HCSO under the same access conditions as the Safe Centre.

Remote execution: For scientific purposes, the HCSO produces the requested research outputs inside its own safe environment based on the specifications/syntax files provided by the researcher.

Release of anonymised microdata sets: By using this data access channel the HCSO provides anonymised microdata sets for the researchers for scientific purposes. Anonymised microdata sets are customised and only the variables requested are provided to the researcher.

The secure access modes (Safe Centre access, remote access and remote execution) provide access to both ready-made and customised microdata sets.
