Book excerpt: Essay Collection Advancing Future Generations-Population Issues in Indonesia and Korea It is with great pride that I introduce the Essay Collection ‘Advancing Future Generations: Population Issues in Indonesia and Korea’, a product of the World Population Day Conference hosted by the Korea-Indonesia Connection (KIC) FISIP UI on 16–17 July 2024. This collection of 23 essays offers valuable insights into the pressing population challenges faced by both Indonesia and Korea, refl ecting the collaborative efforts of scholars and experts dedicated to shaping a better future. Social scientists, in particular, can study population issues in Indonesia and Korea by examining various demographic factors such as birth rates, migration patterns, and aging populations. Research in Korea may concentrate on issues associated with an aging population and declining birth rates, whereas research in Indonesia may concentrate on urbanization and regional disparities. By contrasting these cases, we can gain understanding of how cultural and policy issues infl uence population patterns and the wider effects they have on society. This book is an important outcome of the cooperation between the Korea Foundation and FISIP UI. I am confi dent that this book will serve as an important resource for academics, policymakers, and the broader community, inspiring continued dialogue and action on these vital issues.
