This seminar introduces the famous idea that “demography is destiny”, and then explores this assertion’s relevance and validity through a series of historical and contemporary case studies. "Demography is destiny" means that a population's size, age structure, and other demographic characteristics significantly influence its future economic, social, and political trajectory, essentially dictating its "destiny". Examples include aging populations in developed countries, rapid population growth in developing countries, brain drain(gain) due to migration, migration’s effect on generational well-being, political instability from demographic shifts, gender shifts in education and professions, pandemics effects on medicine and public health, technology and labor market dynamics, and family/household change. We will apply sociological perspectives and reasoning to understand how demographic changes play a significant role, but will stress that other factors like government policies, technological advancements, and social changes also influence society. That is, we will learn how the consequences of demographic trends differ based on a society’s specific economic and social conditions. Restricted to first-year students. Not eligible for CR/NCR option.
