What is population ageing?

Summary

Population aging refers to the increasing proportion of older individuals in society, with a dramatic shift expected by 2050 as the number of people over 60 will double. This demographic change influences multiple aspects of life, from shrinking families to economic challenges such as a decrease in the working-age population and increased demand for healthcare. Societies must adapt by redefining old age, focusing on intergenerational collaboration, lifelong learning, and long-term political strategies to address the challenges and opportunities presented by an aging population.
