Aging Societies & Depopulation: Fewer Wars?
## The Unseen Hand of Age: how Demographics Are reshaping Global Conflict
The global landscape of conflict is poised for a seismic shift, driven not by grand geopolitical strategies or technological arms races, but by a more basic force: aging populations. As birth rates decline and life expectancies lengthen across much of the world, nations face a demographic revolution that will profoundly impact their military capabilities, their willingness to engage in conflict, and ultimately, the prospects for international peace.
one of the most immediate consequences of an aging populace is the shrinking pool of available military recruits.A smaller working-age population directly translates to fewer young men and women available for military service. This demographic squeeze is compounded by the increasing sophistication of modern warfare. as militaries adopt more advanced technologies, such as unmanned aircraft systems, they will likely require a higher caliber of personnel to operate, maintain, and complement these complex systems.A 2022 report by the Congressional Research Service,as an example,highlighted that U.S. military unmanned aircraft systems are expected to demand an equal or greater number of personnel then their crewed counterparts.The challenge of finding these highly capable soldiers will be exacerbated in a world grappling with aging demographics.
while a slower pace of economic growth and a decline in available military resources might suggest a trend towards less capable militaries and, consequently, more peaceful international relations, the opposite is also a distinct possibility.Shrinking military capabilities could, paradoxically, embolden leaders who perceive a narrowing window of chance to employ force to achieve national objectives.However, this impulse will likely be met with significant countervailing pressure from aging populations who tend to favor peace. Decades of survey data consistently show that individuals become more pacific and less inclined to use force as they age. A 2006 Pew Research Center analysis of U.S. surveys revealed a clear generational divide on military interventions, with older Americans consistently expressing greater wariness about using military force. Similarly, research on China in the 2010s indicated that older Chinese citizens were less likely than their younger counterparts to beleive China relied too little on military power or to view the U.S. military presence in East Asia as a major threat.they were also less willing to commit troops to a conflict.
Furthermore, aging populations are likely to exhibit a heightened aversion to military casualties. The loss of young lives, notably those who have not yet had children, can amplify fears that war will permanently weaken an already depopulating nation. In democracies, mounting public opposition to military deaths and casualties can directly jeopardize electoral support for leaders. However, this aversion is not confined to democratic systems. as populations age, authoritarian regimes will also become more sensitive to the potential for wartime losses to incite domestic backlash. By 2030, such as, nearly half of China’s prime military-age cohort will consist of only children. Low fertility rates have already resulted in hundreds of thousands of “bereavement parents” (Shidu) in China, who lost the only child permitted under the former one-child policy. These parents have historically demonstrated annually to demand government support, highlighting a potential source of domestic instability that leaders may consider when contemplating military action. The greater the likelihood that bereaved single-child parents will protest, the more cautious Chinese leaders might potentially be about initiating a war.
Population aging will not, of course, completely eradicate war, as evidenced by Russia’s invasion of Ukraine. However, it will undeniably diminish the capacity of governments to wage war and erode widespread public support for such endeavors. All aging states,nonetheless of their revisionist ambitions or reliance on military aggression,will be compelled to confront the profound implications of this demographic revolution. Demography plays a significant role in determining what is economically and militarily feasible. In this context, aging is poised to become a powerful, unprecedented force for peace.
