The Ministry of Equality , through the Government Delegation against Gender Violence (DGVG) and the Center for Sociological Research (CIS), presented this morning the study "Perception of Prostitution". The Director General of Coordination and Research at the CIS, Silvia García Ramos, thanked the Ministry for the initiative and the trust placed in the Center for Sociological Research, emphasizing that “ultimately, the founding reason and objective of the CIS has always been to collaborate with other administrations to study public opinion in Spanish society, providing quality data that improves the development and implementation of public policies. Because only with good information can good decisions be made.” García Ramos highlighted that the survey represents a pioneering effort and a fundamental milestone, as it is the first time that CIS has conducted a monograph, dedicating an entire questionnaire to asking about the social perception that Spanish citizens have about prostitution and pornography , which has allowed for a deeper exploration of the topic and its analysis from multiple angles. While this isn't the first time the CIS has asked about this issue, as it has revealed: “ It was 40 years ago , in 1986, in a study on the image of military service, in which young men between the ages of 16 and 24 were asked about the justification or lack thereof for prostitution , among many other topics such as drug use, suicide, or paying less taxes. Other questions about the consumption or legitimacy of this practice have also been asked in other studies, such as the 2008 sexual health study.” The Director General of Coordination and Research described the methodological scope employed, based on the CATI system, with telephone interviews and phone numbers chosen completely at random, as is done in all CIS studies. It was designed with a sample size of 10,019 interviews , targeting residents of Spain aged 16 and over, with quotas for sex, age, municipality size, and autonomous community or city of residence. “We haven’t left young people out,” he added. “We didn’t want to forget them because their opinion is also crucial on a topic like this, but we also wanted a large enough sample size so that the results reflect the country’s situation at the time the survey is conducted, and have national, regional, and city representation.” The sheer size of the sample has allowed us to "generate two subsamples, one of men and one of women, with their corresponding weightings. This allows us to go far beyond simply cross-referencing by sex in the questions, to understand the opinions of men and women in a differentiated way according to their different sociodemographic conditions. In other words, we will be able to know, for example, what men think according to their age, the size of their municipality, their education; what women think according to their social class, their voting history, etc. This is a key aspect of the study, because it introduces an important gender perspective to a topic like the perception of prostitution, considerably expanding our knowledge on this subject." And finally, he wanted to acknowledge the fundamental role of the citizens who agree to answer the CIS surveys: “ We thank the citizens who have dedicated a little of their time to answering this survey , and who answer all the surveys that the CIS conducts every day. Thanks to their generosity in giving us this time, we can continue working, continue creating studies, and continue researching the reality of our society. Ultimately, it is they who contribute to providing public authorities with the information needed to develop policies, enabling the scientific community to continue its research, and allowing society and the media to understand the major social trends of our time.” The recognition was extended to the team of pollsters “for their daily work and also to all the technicians who have worked hand in hand with us to make this survey possible, and of course to the CIS staff, specifically the technician in charge of the study. It is thanks to their work and professionalism that we can continue to count on one of the best public opinion institutes that currently exist.” The Minister for Equality, Ana Redondo, began her speech by stating that prostitution “is not a job or just another economic activity, as it is intertwined with poverty, coercion, and vulnerability.” And thanks to this study by the Center for Sociological Research (CIS), the citizens' message is being heard: " It is about science, sociology and demoscopy, and it represents an endorsement for all that legislative and administrative structure that we are promoting ."
