This chapter examines youth civic engagement in the Rio de Janeiro metropolitan region. It first considers the context of young people's civic engagement in Brazil, citing how a series of events in the country's recent history aroused unprecedented levels of political participation. It then considers the demographics of youth activists in Rio, the activities and organizations they are involved in, and their motivations for engagement. It also discusses issues important to youth activists, along with their responsibilities, social awareness, and political ideas; what they perceive as costs to civic engagement, including the fear of violence and the time that activism takes up; and their various other concerns such as the poor state of education in the country and the rights of political participation. The chapter concludes with an assessment of Rio youth's views on responsibility.
