Expanding the conversation about aging

Many issues facing older adults intersect with other social inequalities, but experts often fail to keep the experiences of historically underserved communities in mind when discussing aging. Since 2020, the MIT AgeLab’s Aging and Equity Speaker Series has sought to bring together researchers, advocates, and practitioners who aim to understand how aging-related issues affect a broad array of communities. “We think it’s important to offer a platform at MIT that amplifies the work of researchers who are thinking about issues like...

Pension Systems (Un)Sustainability and Fiscal Constraints: A Comparative Analysis

By Michael Wickens  Using an overlapping generations model, two new indicators of public pension system sustainability are proposed: the pension space, which measures the capacity to pay for pension expenditures out of labour taxation, and the pension space exhaustion probability reflecting demographic uncertainties. These measures reveal that the pension spaces of advanced economies are strikingly different. Most nations have little scope to further finance pensions out of labour income  taxation over the next thirty years. There is no one-size-fits-all solution....

U.S. centenarian population is projected to quadruple over the next 30 years

The number of Americans ages 100 and older is projected to more than quadruple over the next three decades, from an estimated 101,000 in 2024 to about 422,000 in 2054, according to projections from the U.S. Census Bureau. Centenarians currently make up just 0.03% of the overall U.S. population, and they are expected to reach 0.1% in 2054. The number of centenarians in the United States has steadily ticked up since 1950, when the Census Bureau estimates there were just...

The EU Loses About a Million Workers Per Year Due to Aging. Migration Official Urges Legal Options

The European Union’s top official for migration said Monday that member states will have to confront tough policy challenges — even in the current election year – to cope with the continent’s aging population. Ylva Johansson, the EU home affairs commissioner, said there was a pressing need to shift away from illegal migration and find more legitimate alternatives. “For demographic reasons, the population of working age in the EU will decrease by 1 million per year. It is decreasing by 1 million per...

Japan retirement trends: job-seeking seniors double in 10 years

The number of people 65 and older looking for work in Japan has more than doubled over the past decade, government employment center data shows, creating the challenge of matching them with the right jobs in a shrinking labor pool. A Hello Work employment center in Tokyo's Ikebukuro district has a counter just for senior citizens. Some need work to supplement their income, but others just want to stay active. "I want to work until I'm 70," said a 66-year-old man who was there to fill out paperwork...

Female-Specific Aging Trajectories Remain Understudied

Most model organisms don’t match human sex specificity The use of model organisms, such as worms, fruit flies, and mice, has helped researchers to understand many aging processes. However, it is also partly to blame for the lack of data on how pregnancy, breastfeeding, and menopause impact aging-related diseases. Animal research is based on the premise that those organisms and humans share essential physiological characteristics. While true in many cases, there are tremendous differences between the physiology of model organisms and...

China’s population: Beijing urged to build digitally inclusive society, as it seeks insights into technical skills of its elderly

China is seeking to gain more insights into the digital literacy of its elderly population as it attempts to find ways to better accommodate its rapidly ageing demographic in an increasingly intelligent society. New questions on smartphone usage for people aged 60 and above were added to a survey on population changes and the labour force conducted at the end of 2022, and published recently by the National Bureau of Statistics in the 2023 China Population and Employment Statistical Yearbook. They...

The research aiming to keep people healthier for longer

Despite what the young might like to think, ageing is inevitable as adulthood progresses. In How We Age, geneticist Coleen Murphy provides no silver bullets for remaining youthful. Rather, she offers a scholarly account of the state of ageing research that is both lively and personal. She also gives real insight into the ups and downs of leading a research laboratory. The book is a paean to the power of invertebrate model organisms such as the worm Caenorhabditis elegans and fruit fly Drosophila melanogaster,...

How Japan’s aging population is shaping the future of nursing care

How will the aging population impact the provision and sustainability of care? We put the question to Dr Yukari Nakano, Executive Officer at the Japanese Nursing Association People are living longer than ever before, and though this is a positive sign of improvements to physical and social surroundings, many still spend their twilight years in poor health. Population aging also equates to a greater demand for long-term care and an expanded healthcare workforce capable of providing the specialized care many...

Playing the Long Game: How Longevity Affects Financial Planning and Family Caregiving

By Surya Kolluri, Janet Weiner & Mary Naylor Since 1935, when Social Security set the age to receive full benefits at 65, average life expectancy in the United States has risen by 17 years. This increased longevity has clear implications for financial planning, both in terms of the timing of retirement and the need to plan for a longer period of retirement. But there are less obvious implications as well, in terms of the likelihood and length of time that...
