The purpose of the CIS is the scientific study of Spanish society, which is carried out mainly through studies that capture the opinions and attitudes of the population. To carry out this work, the CIS, through this space, and following a general strategy of transparency and modernization, makes available to the general public all the quantitative and qualitative studies that it has been carrying out since its creation in 1963.
Some of the surveys carried out by the Institution are considered state statistics and therefore collected within the National Statistical Plan.
