Chile Unprepared for Rapid Population Aging
Chile is entering a period of fast demographic change. Life expectancy has risen sharply, while fertility has fallen, reshaping the age profile nationwide.
Rising life expectancy and gender gap
Official data show life expectancy at birth grew from 74.0 years in 1992 to 81.1 years in 2024. That is a gain of 7.1 years in roughly three decades.
Women live longer than men. In 2024, average female life expectancy was about 84 years, compared with 79 for men. The gap reflects biological differences and behavioral risks, including occupational hazards, higher smoking and alcohol use, and lower preventive care uptake among men.
Drivers of the improvement
Public health gains underlie much of the increase in longevity. Expanded access to safe water and sanitation helped. Better primary care, nutrition, reduced infant mortality, and advances in medical technology also played roles.
The Covid-19 pandemic caused a temporary dip in life expectancy between 2020 and 2022. By 2024, the trend had recovered, and projections point to further gains. INE forecasts life expectancy will exceed 88 years by 2070.
Demographic projections and speed of change
The age structure is transforming rapidly. In 2024, the aging index exceeded 100, meaning more people aged 65 or older per 100 under 15.
Projections indicate the population over 65 could triple the number of children under 15 by 2045. By 2070, the ratio may approach 600 older adults per 100 young people. The result is an inverted age pyramid similar to Japan and Germany.
Chile’s pace is striking. France took more than 150 years to double its elderly population. Chile is likely to do so in under 30 years.
Fiscal and institutional challenges
These shifts place pressure on pensions, health services, and care systems. Existing pension designs assumed life expectancies of 70 to 75 years. Today, retirements can last 20 to 25 years, creating a gap between savings and benefits.
Health system demands
Longer lives increase chronic disease and geriatric care needs. The health network must adapt. Training specialized professionals will be essential.
Care and infrastructure
There is a structural deficit in long-term care infrastructure and services. Closing this gap will take decades. Early planning and investment are necessary.
Social implications and urgency
Beyond budgets and institutions, the challenge is social. Policy must support healthy aging and opportunities for continued labor participation. Strong protection systems are needed to ensure dignified longer lives.
Many analysts warn Chile is unprepared to face rapid population aging. The speed of change reduces the time available to adapt public systems and social norms.
How authorities and society respond will shape Chile’s future development and the quality of life of coming generations. The column’s author is dean of the Faculty of Economics and Administration at UC.
