Young people have long used popular culture to explore, define and express who they are. For many, popular culture is also a tool of survival. Gone are the days when proscriptive programs were needed for young people to transition to adulthood. Today, youth culture is communicated through information technology, particularly social media, enabling young people to engage the world. Yet, as always, youth culture is often a cause of concern for adults and policy makers. This collection of new essays focuses on modern youth popular culture. There are such topics as social justice and youth mobilization in Ferguson, Missouri, social media and sexual literacy among LGBT youth, and youth culture's influence on children's sports.
