The Comparative Political Data Set 1960-2006 is a collection of political and institutional data which have been assembled in the Logo der Universität Bern context of the research projects „Die Handlungs-spielräume des Nationalstaates“ and “Critical junctures. An international comparison” directed by Klaus Armingeon and funded by the Swiss National Science Foundation. It consists of (mostly) annual data for 23 democratic countries for the period of 1960 to 2006. In the cases of Greece, Spain and Portugal, political data were collected only for the democratic periods[1]. The data set is suited for cross national, longitudinal and pooled time series analyses.

The data set contains some additional demographic, socio- and economic variables. However, these variables are not the major concern of the project, and are thus limited in scope. For a more in-depth source of these data, see the online databases of the OECD. For trade union membership, excellent data for European trade unions can be added from the CD-ROM of the Data Handbook by Bernhard Ebbinghaus and Jelle Visser (Trade Unions in Western Europe since 1945 (The Societies of Europe). New York, Basingstoke, Oxford: Grove’s Dictionaries, Macmillan, 2000).

A few variables have been copied from a data set collected by E. Huber, Ch. Ragin, J. Stephens, D. Brady and J. Beckfield (2004), as well as from a data set collected by D. Quinn. We are grateful for the permission to include these data.
