Demographic shift11/19/2023 ![]() ![]() But these structures need to reflect the substantial differences in quality of life among older adults for example, women generally live longer than men, but with more illness and less financial security. Population aging is already a defining demographic trend of this century, and governments around the world are working to establish and fund systems to support the well-being of older adults. As the global population ages, understanding older adults’ diverse needs and contributions to families and society is essential to inform policy decisions about effective old-age support.The actions countries take as they approach this window of opportunity are likely to have long-lasting economic effects. For some countries, this window may only be open for 10 to 15 years, while an analysis of six countries in the Sahel suggests a window of 30 to 40 years. The window is time limited, closing as the age structure matures and older adults account for a greater share of the population. As fertility declines from high to low levels, countries experience a window of opportunity for sustained economic growth. For many countries with youthful populations, the “demographic window of opportunity” opens between now and 2050.While climate migrants have received significant global attention, more should be done to strengthen the resilience of communities unable to migrate out of harm’s way. But not all populations have the means to uproot their lives in response to climate crises, and often the most vulnerable groups are left behind. Climate change is widely predicted to drive migration within and between countries. As climate change exposes societal inequalities, more attention is needed to the populations unable to migrate when crises occur.Here are eight emerging demographic issues we expect to shape our world in the coming decades: Knowledge of the changes to come enables us to make investments today that will better prepare us for the future. More than 50 other countries will see fertility rates fall below replacement level, and crises driven by climate change will likely fuel migration around the world. In the 15 years between today’s population milestone and the projected Day of 9 Billion in 2037, India will overtake China in population, and Democratic Republic of the Congo and Ethiopia will grow to be among the 10 most populous countries in the world. On November 15, the day the world’s total population is projected to reach 8 billion people, PRB and the Center of Excellence for Research in Generational Economics (CREG) join others in highlighting eight notable demographic trends and issues.
