Centro de Investigaciones Sociológicas, academic publisher in Spain
The Centro de Investigaciones Sociológicas is a research institute in Madrid focused on measuring and analyzing public opinion and social behavior across Spain. It conducts monthly surveys known as the Barómetro, interviewing around 3,000 randomly selected people nationwide to capture what citizens think about current issues and concerns.
The institute was founded in the 1960s as the Instituto de la Opinión Pública but was renamed in 1977 following Spain's transition to democracy. This change reflected a shift toward more open research practices and greater independence from government control.
The institute documents what ordinary Spanish people actually think through monthly surveys and detailed research across the country. By making findings freely available, it helps society see itself more clearly and understand the concerns and values that matter to everyday citizens.
All research findings and datasets are freely available online through the institute's database, making it easy for anyone to explore current surveys and historical data. Visitors can access the information from home or visit the main office in Madrid to learn more about ongoing projects and findings.
The institute publishes its monthly Barómetro surveys in detailed form, allowing researchers and journalists to see exactly which questions were asked and how people responded. This transparency means anyone can examine raw data and draw their own conclusions rather than relying on summaries alone.
