Countries / regions with the most severe population aging trends

Population aging refers to the phenomenon of population distribution skewing toward older ages. Increased life expectancy has led to a growing elderly population, while declining birth rates have reduced the number of young and working-age people. Most developed countries and some developing countries around the world are experiencing significant population aging.

Population aging has a major impact on the economy. As the proportion of the working-age population declines, overall productivity gradually decreases. Existing welfare pension systems face lower contributions from younger generations while required expenditures continue to rise, leading to declining replacement rates and challenging the sustainability of pension systems. Some believe that advances in technology and automation can mitigate the impact of population aging, but the proportion of elderly population worldwide will continue to rise in the foreseeable future. This is a social problem unprecedented in human history.

Listed below are the countries/regions with the most severe population aging trends before 2050.
