Free access to CIS data files with no charge

The Centro de Investigaciones Sociológicas is pleased to announce that all users of our webpage can download, completely free of charge, its survey data files.

The rollout of this service is part of a set of measures designed to improve transparency in data access as well as the operational efficiency of the CIS.

Access to the data files will be made available in stages. On 1 January 2009 the surveys carried out in 2008 and 2007 will be made available to the public. During the course of the following months all the surveys carried out since 1995 will be added. Files prior to 1995 will be added at a later date, providing the age of the data so permits.

The data files, in ASCII format, appear in a compressed file that can be downloaded from the webpage, after filling in a simple form. The syntax file (in the SPSS and/or SAS statistical package files), the questionnaire, the technical specifications, the code book and the cards may also be freely accessed. Logically, the data provided will be suitably processed to ensure anonymity.
