What is the impact of demographics on the prospective production of military power and the causes of war? This monograph analyzes this issue by projecting working-age populations through 2050; assessing the influence of demographics on manpower, national income and expenditures, and human capital; and examining how changes in these factors may affect the ability of states to carry out military missions.

The field of political demography - the politics of population change - is dramatically underrepresented in political science. At a time when demographic changes - aging in the rich world, youth bulges in the developing world, ethnic and religious shifts, migration, and urbanization - are waxing as never before, this neglect is especially glaring and starkly contrasts with the enormous interest coming from policymakers and the media. "Ten years ago, [demography] was hardly on the radar screen," remarks Richard Jackson and Neil Howe of the Center for Strategic and International Studies, two contributors to this volume. "Today," they continue, "it dominates almost any discussion of America's long-term fiscal, economic, or foreign-policy direction." Demography is the most predictable of the social sciences: children born in the last five years will be the new workers, voters, soldiers, and potential insurgents of 2025 and the political elites of the 2050s. Whether in the West or the developing world, political scientists urgently need to understand the tectonics of demography in order to grasp the full context of today's political developments. This book begins to fill the gap from a global and historical perspective and with the hope that scholars and policymakers will take its insights on board to develop enlightened policies for our collective future.

Military recruitment will become more difficult in times of demographic aging. The question arises whether demographic change will constrain the capacity of aging states like Germany to conduct foreign policy and pursue their national security interests. Since contemporary military operations still display a strong human element, particular scrutiny is given to the empirical analysis of the determinants of military propensity and military service among youth. An additional human capital projection until 2030 illustrates how the decline in the youth population will interact with trends in educational attainment and adolescent health to further complicate military recruitment in the future. A concluding review of recruiting practices in other NATO countries provides insight in best-practice policy options to reduce the military’s sensitivity to demographic change. Following this approach, the book gives prominence to a topic that has thus far been under-represented in the greater discussion of demographic change today, namely the demographic impact on international affairs and strategic calculations.

"The ongoing COVID-19 pandemic marks the most significant, singular global disruption since World War II, with health, economic, political, and security implications that will ripple for years to come." -Global Trends 2040 (2021) Global Trends 2040-A More Contested World (2021), released by the US National Intelligence Council, is the latest report in its series of reports starting in 1997 about megatrends and the world's future. This report, strongly influenced by the COVID-19 pandemic, paints a bleak picture of the future and describes a contested, fragmented and turbulent world. It specifically discusses the four main trends that will shape tomorrow's world: - Demographics-by 2040, 1.4 billion people will be added mostly in Africa and South Asia. - Economics-increased government debt and concentrated economic power will escalate problems for the poor and middleclass. - Climate-a hotter world will increase water, food, and health insecurity. - Technology-the emergence of new technologies could both solve and cause problems for human life. Students of trends, policymakers, entrepreneurs, academics, journalists and anyone eager for a glimpse into the next decades, will find this report, with colored graphs, essential reading.

This report discusses the relationship between population and environmental change, the forces that mediate this relationship, and how population dynamics specifically affect climate change and land-use change.
