The document discusses an analysis of citizen participation data from Decidim Barcelona, an online platform for citizen participation in Barcelona city planning. The analysis found over 10,000 proposals submitted online, with over 165,000 votes and 18,000 comments. Offline, there were 410 physical meetings with over 11,000 attendees. The goal is to detect patterns in citizen participation across urban areas and identify topics of most interest to help promote more equal participation. Future work will examine factors like Internet access that could affect participation inequality across districts.
