This edited volume is intended to showcase the breadth and depth of the collaborative intellectual enterprise that the Asian Barometer Survey (ABS) network has built up over the past two decades. To commemorate the twentieth anniversary of the ABS, we invited ABS partners to contribute their intellectual findings to this edited volume. Except for the introduction, this volume consists of twenty-seven chapters divided into two sections. The first part of the book contains eleven chapters that are based on previously published studies and are updated based on the latest ABS data. The second part of the book focuses on issues specific to each country or autonomous territory and consists of sixteen chapters. Among the topics discussed are potential threats to third-wave democracies, evolving ideology in one-party states, cases of denied democracy, and peculiar challenges faced by long-term democracies. The contributors are the indispensable partners that have made the ABS possible over the past two decades. In addition to celebrating the long-term collective efforts of those who participated in the ABS project, this edited volume also sets out to address the ongoing debate over the future of democracy in Asia.
