Based on a 30-question test on the most divisive issues in Spain, to which 5,534 respondents have been subjected, the French demoscopic company Cluster17 has identified, through the use of a statistical algorithm, 16 clusters, which correspond to the 16 families or Spanish political tribes. Its members share a system of opinions, values, a way of seeing the world.
You can read the description of each group, ordered ideologically from left to right, below. The accompanying illustrations, created by Cluster17, seek to reflect the dominant demographic characteristics of each group.
