How do you construct a political agenda? Co-participation patterns of social organizations in the 2009-12 Chilean protests

This paper analyse the network of social demonstrations of the recent “Chilean Student Winter” occurred between 2009 and 2012 by studying the co participation patterns of social organizations using social network analysis. We describe main social actors and study the topological characteristics of the networks formed through social organizations, demonstrations and motives. Also, we study the change in the density of the network of demonstrations due to the rise of the “Chilean Student Winter” at 2011. We found that in spite that the “Chilean Student Winter” was mainly a student revolution, organizations of workers are the protagonist of this period according to the network analysis. Additionally, there are a significant change in the global cohesion or density of the demonstration’s network at 2011-12 in relation to 2009-2010.
