On the roles of social science archives

Criticism is what inspires the growth of knowledge - at least in societies that are influenced by the Western world's tradition of rational discourse. In this sense, social research archives create a space for the critical discussion of research results by providing access to data already published and analysed by others. Quite apart from their function of placing research datasets in the public domain and ensuring equal access to them, data archives also increase the cost-effectiveness of research by making primary data collections available for secondary analysis. 

How to use TÁRKI Dataarchive?

General procedure

1. Search our collection using either catalogue search or documentation search. Note: catalogue search will search on datasheets (metadata on data collections either by title, researchers, institutes, abstracts or keywords); documentation search is for searching in codebooks and questionnaires. Some of the documentation is only available in Hungarian.

2. Select the identifier of the data collection you want to use. The ID number is made up of a letter and a two-digit number (e.g. A01, F99, etc.). These numbers are used to identify a data collection (dataset) unambiguously. ID number details are needed to retrieve your data requests as quickly as possible.

3. Check the data access category. Note: some of the data collections are embargoed for a period of time (maximum of 5 years). These restricted-access data collections are identified as category D - that is, Delayed dissemination. If you want to use such a collection, you can contact the researcher (primary investigator) or us (mail to: to request individual access to a restricted-use (category D) data collection. You can check the access categories we use here.

Note on access to aggregate cross-national ISSP, Eurobarometer, WVS and ESS surveys

Cross-national comparative data collections are stored in archives appointed by the research programmes. These archives are responsible for creating user documentation and for distributing the most up-to-date versions of datasets.
  • The ISSP archive is the Zentralarchiv für Empirische Sozialforschung at the University of Cologne, Germany. The archive is responsible for archiving, integrating data and documentation and for the distribution of the merged international datasets for the Programme. Since 1997 the ZA is supported in the processing of data by the Spanish ISSP partner ASEP, Madrid.  Visit the archive's own pages for detailed information on the ISSP archive. The ISSP Service Guide provides information about search facilities, codebooks and field-questionnaires, data-sets and products available, research, news and also about the archiving rules. Any questions about archiving and data should be sent to the Zentralarchive.
  • Aggregate Word Value Survey File Distributors: Análisis Sociológicos Económicos y Políticos (ASEP) and JD Systems (JDS), Madrid, Spain / Tillburg University, Tilburg, The Netherlands / Zentralarchiv fur Empirische Sozialforschung (ZA) Cologne, Germany. For direct accession to WVS via web see WVS website.
  • Eurobarometer data and documentation (questionnaires, codebooks etc.) are stored at the ICPSR and at the Zentralarchiv and made available by the Social Science Data Archives for social science research purposes.
  • ESS data (Round 1, Round 2, and aggregated file) are accessible via the ESS data archive at Check for details at ESS website. (, where registered users can download data collections from ESS data archive.
TRKI Data Archive distributes the Hungarian versions of some of the studies listed above. Hungarian users of international aggregate data collections may ask for assistance in obtaining datasets from the archives responsible. Browse ICPSR catalogue.
