Populations Shift to Older People: Pyramid to Cube POPULATION

advertisement
Most advanced economies face shrinking workforces, while many young countries face explosive growth.
POPULATION AGING WILL RESHAPE
GLOBAL ECONOMICS AND GEOPOLITICS
Europe’s working-age population is projected to decline by 10%, or nearly 50 million. Less developed countries are projected
to see a work-force gain of nearly 1 billion, with about half of that occurring in Asia and nearly 40% in Africa.

Populations Shift to Older People: Pyramid to Cube
As fertility falls and longevity increases, a country’s age profile changes from a pyramid with a broad base of young people to a cube with a more
even distribution across age brackets. If fertility remains low, the population will become top-heavy with older people.
The share of older people (65+) is increasing almost everywhere, but at different rates depending on changes in fertility and longevity. These
population age shifts have profound impacts on everything from a country’s work-force growth and economic prospects to public and personal
budgets, security risks, cultural institutions and family structures.
Oldest Countries: Working-age populations shrink; age structures become top-heavy with old people.
• Fertility has been below replacement
level of 2.1 births per woman for the
last 15-20 years.
• Working-age population (15-64) is
shrinking.

Population, 2010-30
• Declining work-force growth

burden of retirees threatens economic

The Global Aging Program at the Stanford Center on Longevity focuses on the economic and political implications of longevity. The
program specifically addresses the risks and opportunities of population age shifts around the world. Understanding the implications of these
Population Age Shifts will be critical for effective policy making.
The Stanford Center on Longevity is working to transform the culture of human aging. The Center studies the nature and development of
the entire human life span, looking for innovative ways to use science and technology to solve the problems of people over 50 and improve
the well-being of people of all ages. To inspire change of this scale, the Center brings together the best minds in academia, business and
government to target the most important challenges and solutions for older populations. The Center was founded by two of the world’s
leading authorities on longevity and aging, Stanford professors Laura L. Carstensen, PhD, and Thomas Rando MD, PhD, and received its
initial funding from Texas investor Richard Rainwater.

Adele Hayutin, Ph.D., Senior Research Scholar and Director of SCL's Global Aging Program, is a leader in the field of comparative
international demographics and population aging. Dr. Hayutin combines broad knowledge of the underlying data with the ability to translate
that data into practical, easy to understand language and implications. She has developed a comparative international perspective that
highlights surprising demographic differences across countries and illustrates the unexpected speed of critical demographic changes.
Previously she was director of research and chief economist of the Fremont Group (formerly Bechtel Investments) where she focused on
issues and trends affecting business investment strategy. Dr. Hayutin received a BA from Wellesley College and a Master's in Public Policy

Dramatic and unprecedented shifts toward older age brackets are occurring at vastly different
rates around the world. Understanding these differences is critical for developing policies that
effectively address the economic and geopolitical challenges of population aging.
