The U.S. has a record low fertility rate. Is that good news or bad news? It’s complicated.

The U.S. fertility rate — the average number of children each woman gives birth to — fell 22% between 1990 and 2023, according to the latest data from the Centers for Disease Control and Prevention’s National Center for Health Statistics (NCHS). It’s not a new trend; the decline began in 2007, just ahead of the 2008 recession. Coupled with the rapidly aging American population, the falling fertility rate has long made policymakers nervous about draining Social Security funds and generally causing...

South Korea’s birthrate rebounds, but is it sustainable?

After nearly a decade of birth rates in steady decline, South Korea reversed that trend to report a significant uptick in newborns in 2024. Announced by the government-run Statistics Korea agency on February 26, a total of 238,300 babies were born last year, up 3.6% from a record low of just 230,000 in 2023. And while the increase is certainly grounds for celebration in a nation that is recognized as one of the most rapidly contracting and aging in the world, analysts caution that...

Climate Change May Drive Premature Aging

A new USC Leonard Davis School of Gerontology study suggests greater exposure to extreme heat may accelerate biological aging in older adults, raising new concerns about how climate change and heat waves could affect long-term health and aging at the molecular level. People in neighborhoods that experience more days of high heat show greater biological aging on average than residents of cooler regions, said Jennifer Ailshire, senior author of the study and professor of gerontology and sociology at the USC Leonard Davis School. Biological...

AI robots may hold key to nursing Japan’s ageing population

Recently in Tokyo an AI-driven robot leaned over a man lying on his back and gently put a hand on his knee and another on a shoulder and rolled him onto his side -- a manoeuvre used to change diapers or prevent bedsores in the elderly. The 150-kg (330 lb) artificial intelligence-driven humanoid robot called AIREC is a prototype future "caregiver" for Japan's rapidly ageing population and chronic shortage of aged-care workers. "Given our highly advanced ageing society and declining births,...

Chart of The Month: Declining Global Fertility Rates

The global fertility rate is expected to decline to 2.8 children born per female in 2025 from 3.1 a decade ago. Among the top 20 economies, the rate will fall to just 1.7, well below the replacement level of 2.1 (the level at which a population replaces itself naturally). Saudi Arabia is projected to have the highest fertility rate in this group, driven by cultural values, historical pronatalist policies, and social factors. Traditional views have promoted larger families, but...

South Korea’s fertility rate increases for first time in nine years amid marriage surge

South Korea’s birthrate rose for the first time in nearly a decade, preliminary data showed Wednesday, raising hopes that the country has started to turn a corner on its demographic crisis. The average number of babies per woman increased from 0.72 in 2023 to 0.75 last year, still the lowest in the world and far below the replacement rate of 2.1. SIGNALS Birthrate supported by surge in marriages after government measures A spike in marriages post-pandemic may be one factor driving the increase...

Long-running surveys help researchers track trends in aging

One of the largest recipients of National Institutes of Health funding at Johns Hopkins University is the Center on Aging and Health, an interdisciplinary effort spanning medicine and public health. And for good reason: There will soon be more adults aged 65 and older than children aged 5 and younger, according to U.S. census data. "This critical juncture accentuates the important nature of our research, which enables older adults to live longer, healthier, and more independent lives," Jennifer Schrack, director of the Center...

The Biggest Challenges Facing Older Americans: Insights from the Aging Advisory Group

Adults aged 50 and older are the fastest-growing age group of those experiencing homelessness, making up nearly half of the single-adult homeless population, which is estimated to triple over the next decade. Older adults are especially vulnerable to becoming homeless, as many live on fixed incomes that are insufficient to cover the cost of housing and other expenses. Aging Advisory Group To address the rapid increase of older adults experiencing homelessness, the National Alliance to End Homelessness, in partnership with the RRF...
