US, European countries lead in quality aging

July 26, 2017

A new instrument to gauge the health and well-being of aging populations, The John A. Hartford Foundation Index of Societal Aging, was created through a collaboration between USC and Columbia University health and policy experts who will launch it this week. They will be available for interviews. Additional details are below.

July 26, 2017 – Researchers from USC and Columbia University have developed a new index that measures how well countries are adapting to dramatic increases in the aging population.

The John A. Hartford Foundation Index of Societal Aging was developed by researchers at the USC Leonard D. Schaeffer Center for Health Policy and Economics and the Columbia University Mailman School of Public Health. The index is based on five economic and social indicators that reflect the status and well-being of aging residents in 30 countries, from the United States to western Europe.

Researchers leading the collaboration unveiled the new index on Wednesday at the International Association of Gerontology and Geriatrics’ World Congress in San Francisco.

“The index provides an accurate look at how well societies are adapting to this aging challenge,” said Dana Goldman, Distinguished Professor and Leonard D. Schaeffer Director’s Chair at the USC Schaeffer Center. “Utilizing reliable and sensitive economic and social indicators that are widely available, the tool allows countries to take a broader view of both current conditions and likely future demographic realities.”

5 indicators of health, well-being

The Hartford Aging Index comprises five indicators that provide new context for measuring the health of aging populations, including an evidence-based metric to assess effectiveness over time and in many countries, the researchers said. Prior indices either made comparisons for a select group of industrialized nations only – at times excluding the United States – and they were heavily weighted on economic metrics, such as working late in life.

“Now that previously unimagined numbers of older persons are living longer, it is critical that we shift from our prior sole focus on the characteristics of individuals and their immediate environments to one that includes a strategy for the entire society to successfully adapt to an aging population,” said John Rowe, the Julius B. Richmond Professor of Health Policy and Aging, Health Policy and Management at the Mailman School of Public Health who led the interdisciplinary team of researchers.

A sample analysis of the data shows that the five countries in the index coping best with their aging populations are: Norway, Sweden, the United States, the Netherlands and Japan. (See charts)

The rankings in the overall multidimensional index, weighted across all five domains, show that there is room for improvement, even among these top-ranked countries. The U.S. overall score for achieving healthy aging, 59.8 percent, signifies that the country is more than halfway toward the goal, while Norway, at 65 percent, is even further ahead.

“Interestingly, the index demonstrates that the United States – despite general problems with inequity and social cohesion – has done well in keeping older Americans financially secure, productive, and engaged,” Goldman said.

The researchers said prior similar tools have provided an incomplete picture of aging as they failed to capture inequalities within advanced and developed aging societies. In some cases, they did not account for other key indicators of an aging society.

Rowe, Goldman and USC Schaeffer Center fellow Cynthia Chen presented details of The Hartford Aging Index at the conference. The five indicators are:

· Productivity and Engagement: Measures connectedness within and outside the workforce.
· Well-being: Measures the state of being healthy.
· Equity: Measures gaps in well-being and economic security between the haves and have-nots.
· Cohesion: Measures across generations and social connectedness
· Security: Measures support for retirement and physical safety.
“Failure to adapt to aging is a risky strategy for a country,” Rowe said. “If we neglect to develop and implement effective policies we will be left with a society rife with intergenerational tensions, characterized by enormous gaps between the haves and the have-nots, and unable to provide needed goods and services for any of its members—especially a progressively older and more dependent population. The good news is this gloomy scenario is avoidable.”

The Hartford Aging Index is now available online at agingsocietynetwork.org.
