The main function of the Centro de Investigaciones Sociológicas (Sociological Research Centre), or CIS, is to study the attitudes and behaviour of Spanish society and measure its stability and changes over time. This yearbook is part of a series which began in 2012, and synthesises the results of monthly opinion polls carried out in the form of personal surveys in 2014. It presents questions of special relevance, some of which are repeated each month, while others reflect a single subject that is the focus of each survey. The yearbook is a visual and accessible presentation of the data this institution gathers each year.

This volume includes an initial section giving a detailed description of the methodology used throughout this document, ten themed chapters, and an appendix with the technical data from the studies used for this yearbook. The first two chapters are longitudinal, and show perceptions about the economic and political situation, and the evaluation of the government and the opposition. They are followed by eight monographic chapters, addressing subjects such as languages, joint responsibility, consumer habits, sports, sociability and communication technology, social habits, the practice of reading and fiscal policy opinion.

The tables presented show which type of interviewee is more likely to have each opinion gathered in the surveys, according to a selection of characteristics. These include sociodemographic features such as gender, age, level of education, employment, marital status and socioeconomic status, but also others such as the size of the town where they live, ideology, voting records and religious practice. In this way, as well as presenting the general opinion of interviewees, the yearbook offers the possibility of examining specific groups.

The databases used to create this yearbook and all the surveys, series and questions asked by the CIS since 1999, are available on its website ( where they can be consulted or downloaded free of charge.
