This book discusses opportunities and limitations to democratic participation in institutions and organizations across the life course. It demonstrates that democratic participation is not something that is learned once and for all and applied in formal political settings, but something that is lived every day throughout life in various contexts. Institutions and organizations frame human lives and strongly determine the ability to participate and co-determine their communities. They are places for learning, deliberation and the development of the common good. The book conceptually and empirically analyses the potential of democratic participation within various institutions. The contributions range from early childhood institutions, schools, youth programs, workplaces, and vocational education to cultural organizations and nursing homes for the elderly. The book thereby provides a cross-sectional and interdisciplinary knowledge base to inspire future research and practical efforts to promote democratic participation within and across institutions around the world.
