Population ageing is no longer a distant projection; it is an unfolding global reality. The
global population aged 60 or over is projected to rise from approximately 1.22 billion in 2025 to more than
2.1 billion by 2050, a transformation that is without historical precedent, most pronounced in
developing regions. Growth is fastest at the oldest ages:
populations aged 80 or over are expected
to more than double, and the number of centenarians to increase more than fourfold by mid-century.
In 2025, remaining
life expectancy at age 60 varies substantially across regions, from 17.4 years in
Africa to 24.9 years in Oceania, reflecting deep inequalities in access to health, social protection and
economic opportunity. Despite significant overall gains,
healthy life expectancy has not kept pace with longevity in many
settings. Low-income regions have achieved substantial gains in healthy life expectancy, while highincome countries have seen a marked slowdown in improvement after 2010, demonstrating that
wealth alone does not guarantee healthy longevity, and that sustained policy investment remains
essential regardless of income level.
