This book offers new insights into the political representation of young people globally. The authors address key issues such as the effects of different levels of government, the role of institutional reforms (e.g., the introduction of youth quotas), the impact of legislative turnover, and the link between descriptive and substantive representation. Featuring contributions from academics, but also activists and practitioners, the volume amplifies voices from all continents, enriching the discourse beyond its traditional European-centric focus. As the first significant exploration of its kind, it not only maps the current state of youth political representation but also illuminates the struggles and triumphs that young adults encounter in political spheres, offering fresh insights into the barriers and opportunities young people face in gaining a seat at the table and remaining there.
