Demographic trends have played a decisive role in precipitating many of the great upheavals of history. Global Aging and the Outlook for Growth and Stability in the Developing World argues that by the 2020s they may once again threaten widespread disruption. The issue brief, which is jointly published by the Global Aging Institute (GAI) and the Pacific Pension & Investment Institute (PPI), explores how demographic change will reshape the economic, social, and geopolitical environment over the next few decades. It focuses on the outlook for the developing world, where the impact of global aging is both more complicated and less well understood than in the developed world. While the “demographic transition” now under way in the developing world may ultimately push it toward greater prosperity, stability, and peace, the issue brief warns that the progress is unlikely to be linear. Indeed, from lingering youth bulges in sub-Saharan Africa and parts of the Greater Middle East to premature aging in China and population implosion in Russia, demographic trends may prove to be every bit as disruptive in this century as they were in the last.
