Welcome to the Center for Sociological Research | CIS

On October 18, 2010, the Interterritorial Council of the Spanish National Health System approved the National Strategy for Sexual and Reproductive Health (ENSSR). The development of this Strategy is part of the implementation of Organic Law 2/2010, of March 3, on sexual and reproductive health and voluntary termination of pregnancy. Its main objectives are to promote the generation of knowledge that contributes to improving the quality of sexual health care from a holistic and gender-based perspective, and to manage, compile, and disseminate existing knowledge on sexual health. To meet these goals, the Ministry of Health needs to understand public opinion regarding the habits and perceptions surrounding sexual health and experiences of the Spanish population over the age of 16. In 2009, the Women's Health Observatory of the National Health System, together with the Center for Sociological Research (CIS) , conducted the First National Survey on Sexual Health , the objective of which was to obtain an initial diagnosis of the state of sexual health at the state level, with a view to developing a sexual health strategy. Currently, the General Directorate of Public Health and Health Equity has considered it necessary to update this information, again in collaboration with the CIS , and for this purpose they have signed an agreement for the II National Survey of Sexual Health, whose fieldwork will be carried out between October 13 and 28, 2025 . The CIS is an agency of the General State Administration that belongs to the Ministry of the Presidency, Justice, and Parliamentary Relations. Its purpose is the scientific study of Spanish society. The CIS is responsible for organizing the survey and also acts as the controller for the processing of personal data. Its headquarters are in Madrid (Calle Montalbán 8, 28014 Madrid). How do we collect data? The questionnaires will be administered via a CATI (computer-assisted telephone interview). If you do not wish to answer any of the questions, you may do so. We conducted the survey on a sample of the population residing in Spain, over 16 years of age and of both sexes. The phone numbers called are obtained by generating random numbers and are placed using an automatic call system. No databases are used, nor is data sharing practiced. The phone numbers are not stored and are disconnected from the interview immediately afterward. No information that could identify the interviewee is requested. All information collected is treated with complete confidentiality, in accordance with the General Data Protection Regulation (GDPR) and national data protection legislation.

The Spanish Centre for Sociological Research (CIS) has completely redesigned its website to offer a simpler, faster, and more accessible experience for all users. The new site allows for easy navigation from any device—computer, tablet, or mobile phone—and facilitates access to all CIS information and studies. The content and organization of information have also been improved, making it easier to find the data and publications of interest. Improvements have also been made to increase the online presence and ranking of CIS content. Thanks to these updates, the portal is now more visible in search engines like Google and Bing, making it easier for researchers, students, and anyone interested to find the available studies and resources. One of the most significant milestones has been the development of a new intelligent search engine with filters and categories , allowing simultaneous searches across all studies, questions, and series produced by the CIS since its founding. This advanced tool is integrated with the Lucene query system, enabling researchers and analysts to run complex, high-precision queries to extract valuable sociological information. In addition, a comprehensive review and update of the translations has been carried out, aimed at improving the coherence and multilingual quality of the content, as well as the integration of CIS study data with the national open data portal datos.gob.es , strengthening institutional transparency and promoting the reuse of public information. With this set of improvements, the CIS consolidates its commitment to digital transformation, innovation and accessibility, reaffirming its commitment to open, rigorous social research at the service of citizens.
