Microdata access conditions
General conditions

Researchers affiliated to recognised universities or other higher education and research institutions may have access to anonymised microdata from social surveys (no business data) for scientific and statistical purposes. The individual researcher and the institution take joint responsibility for use of the data.

Conditions for non-resident researchers

Non-resident researchers from the EU and affiliated countries may apply for access under the same conditions as national researchers. Contract procedures and requirements are slightly simplified (in terms of signatures, in particular), but the information to be provided, obligations, and fees are the same.

Conditions for students

PhD students and higher may apply for access to data.
