Elgar Research Agendas outline the future of research in a given area. Leading scholars are given the space to explore their subject in provocative ways, and map out the potential directions of travel. They are relevant but also visionary. Exploring how demographic dynamism continues to shape the character of societies, this forward-looking Research Agenda offers insights into how the human population has undergone fundamental demographic shifts, and the impact these have had on how we organize ourselves politically, the design of our economic systems, and even our societal relationships. The Research Agenda first introduces readers to the foundations of demographic change: fertility, mortality and migration. Chapters examine the political impact of forced migration, urbanization, gender dynamics, the intersection of race, identity and electoral politics, religious and ethnic groups, and health. The implications of the geographic shift in population centres from the Global North to the Global South are also highlighted, as well as the relationship between demography on the one hand and political and economic power on the other. This will be an invigorating read for social science scholars looking to develop their research or interact with current research trends, particularly scholars of human geography, development studies and geopolitics.
