Millennials or Generation Y-those born between 1981 and 1996-represent the population cohort who are moving into the prime of their careers and lives. It is this generation that is being groomed to take up leadership roles in various sectors of society. In Indonesia, those from the millennial generation are slated to take up positions as leaders in various important spheres of society. However, the country's demographic changes call for comprehending the intergenerational gap that is at the core of the so-called millennial disruptions. This book is a compendium of writings to provide a broad picture of the role of millennials in Indonesia's future. One chapter covers generational differences in life course events; two chapters cover the role of millennials in changing the political landscape; two chapters delve into generational differences in risk-taking behaviours in the financial sector and digital competency among MSME entrepreneurs; two chapters examine millennials' religious views on the cryptocurrency economy and generational differences in the spiritual process of self-discovery; and two chapters study participatory art among millennials and how millennial artists respond to NFT technology.
