James Hillman insightfully remarked, “The 21st century may not turn green with ecological consciousness, but it will undoubtedly turn gray with population aging.” The global aging landscape in 2024 is particularly noteworthy, marked by a significant rise in the proportion of elderly populations across nations. While this trend is universal, its intensity and pace vary by country. According to the latest data from the United Nations and other authoritative sources, the population aged 65 and above is growing rapidly. In developed regions such as Japan and Europe, the elderly already constitute a persistently high and rising share of the population, profoundly reshaping socioeconomic structures. Meanwhile, populous nations like China, Germany, Japan, and the Russian Federation have either reached or are approaching population peaks, with elderly demographics claiming an increasingly prominent role.
