    Global population aging is accelerating, with a larger proportion of individuals aged 60+ projected by 2025. Urgent government planning for social programs for the aged is recommended due to these demographic shifts.

    Area of Science:

    • Demography
    • Sociology
    • Public Health

    Background:

    • Global population structures are undergoing significant shifts.
    • Understanding these changes is crucial for social and economic development planning.

    Purpose of the Study:

    • To review global population structure trends and their determinants.
    • To analyze projected changes in age structure and their socio-economic implications.
    • To compare United Nations (UN) population projection series.

    Main Methods:

    • Comparative analysis of UN population projection data (1984, 1986, 1988).
    • Review of demographic trends and their drivers.
    • Case study analysis (Japan, European countries).

    • Recent UN projections indicate a higher proportion of the global population aged 60 and over in 2000 and 2025 than previously estimated.
    • This trend is observed globally and across major regions, including developed and developing areas.
    • Increased life expectancy is a key driver of population aging, alongside fertility decline.

    Conclusions:

    • Population aging is a significant global trend requiring immediate attention.
    • Governments must prioritize planning for social programs to support the elderly.
    • Demographic shifts necessitate proactive policy responses for sustainable development.
