We, the young people of Urban Talent, an urban cultures association based in Fresnes (Val-de-Marne), are leading this project to create a major citizen quiz: "Who knows their city best?". Through workshops, a field survey and a public event broadcast live, we compare the knowledge and perceptions of young people, residents and elected officials on issues that concern us (youth, culture, security, sport, ecology, public services). Our objectives: strengthen our participation in local democratic life, develop our critical thinking and public speaking skills, promote direct dialogue with decision-makers, and give a voice to residents of disadvantaged neighborhoods.
