EL PAÍS and Cadena SER have released the July barometer by 40dB., including voting intentions and a justice report. All underlying survey data and documentation are now freely accessible. The release offers new transparency for Spain’s sociological research.
For the first time this July, EL PAÍS and Cadena SER have made the complete internal data from their monthly barometer, conducted by 40dB., available to the public. The release includes not only the headline results on voting intentions and perceptions of justice in Spain, but also the full statistical documentation behind the findings. This move opens up the entire foundation of the sociological study, offering unrestricted access to the raw data, questionnaires, and detailed cross-tabulations used in the analysis.
According to EL PAÍS, the newly published files allow anyone to examine the survey’s methodology and individual responses. The documentation covers the full range of materials: the official results report, the original questionnaire, anonymized individual answers, and the cross-analysis that underpins the published conclusions. Multiple formats are provided to facilitate independent review and further research.
The July barometer, produced by 40dB., focuses on two main areas: current voting intentions across Spain and a comprehensive assessment of the justice system. The survey’s internal data, now accessible without restrictions, is intended to support transparency and enable deeper scrutiny of the sociological work. By making these resources public, EL PAÍS and Cadena SER aim to strengthen trust in the survey process and encourage informed debate on the issues covered.
In recent years, the demand for open data in public opinion research has grown, especially regarding electoral trends and institutional trust. The availability of full survey datasets allows academics, journalists, and interested citizens to verify findings, replicate analyses, and explore new questions using the same information as the original researchers. This approach aligns with broader European trends toward open science and data transparency in social research.
Spain’s barometer surveys, such as those by 40dB., play a significant role in tracking shifts in public sentiment and political preferences. The inclusion of justice system perceptions in the July edition reflects ongoing public interest in legal institutions and their performance. By providing access to the underlying data, EL PAÍS and Cadena SER contribute to a more open and accountable public debate, supporting both media transparency and the integrity of sociological research in Spain.
