A Historic Shift Is Happening: Older Adults Now Outnumber the World’s Youngest Children
The world is experiencing a major demographic change, and older generations are at the center of it.
For the first time, the number of people age 65 and older worldwide has surpassed the number of children age 5 and younger, according to new demographic estimates highlighted by the U.S. Census Bureau.
It is a milestone that tells a much bigger story about longer lives, smaller families and how societies around the world are changing.
For Americans approaching retirement—or already enjoying it—the trend could have important implications for health care, caregiving, retirement programs and the way communities are designed in the decades ahead.
America Is Getting Older Too
The United States is experiencing the same transformation.
According to Census Bureau estimates, approximately 61.2 million Americans were age 65 or older in 2024, representing about 18% of the U.S. population.
That share has been climbing steadily as the large Baby Boomer generation moves further into retirement age.
At the same time, Americans are generally having fewer children than previous generations.
Together, longer life expectancy and lower birth rates are changing the traditional shape of the population.
For much of modern history, societies contained substantially more young children than elderly adults. That balance is gradually shifting.
Why This Matters
An aging population is not simply about birthdays.
It can influence nearly every part of society.
More older Americans can mean greater demand for doctors, nurses, caregivers, assisted-living services and transportation designed for people with limited mobility.
Families may also increasingly find themselves caring for aging parents and grandparents while continuing to work and raise children of their own.
Retirement systems will be another major part of the conversation.
Social Security and Medicare already serve tens of millions of Americans. As the population continues aging, policymakers will face increasing pressure to ensure these programs remain capable of serving future generations.
People Are Living Longer
There is also a positive side to the story.
Millions of people are reaching ages that previous generations were less likely to experience.
Many Americans remain active well beyond traditional retirement age. Some continue working, volunteering, traveling, helping raise grandchildren or participating in their communities.
Growing older today does not necessarily look the same as it did several decades ago.
A person turning 65 may still have many active years ahead.
That creates opportunities as well as challenges.
Older Americans carry decades of professional experience, family knowledge and life lessons that can continue benefiting younger generations.
Families Are Changing
The demographic shift can already be seen inside American families.
Grandparents and even great-grandparents are increasingly present for important milestones in children’s lives.
At the same time, smaller family sizes can mean fewer adult children available to provide care when parents become elderly.
That could make professional caregiving and community support increasingly important.
For many families, conversations about retirement savings, housing, health care and long-term care may need to begin earlier than they once did.
Communities May Need to Adapt
Cities and towns could also look different as their populations age.
Accessible transportation, safe sidewalks, nearby medical services and affordable housing can become increasingly important when a larger percentage of residents are older.
Businesses may adapt as well.
Everything from travel and entertainment to technology and financial services is increasingly paying attention to older consumers.
The stereotype that older adults are disconnected from technology is also becoming outdated.
Today’s retirees routinely use smartphones, social media, online banking and video calls to stay connected with family and friends.
Future generations of retirees will likely be even more digitally connected.
A Worldwide Transformation
This is not happening only in America.
Many countries in Europe and Asia are aging even faster, while some younger populations remain concentrated in parts of Africa and other developing regions.
The result is a world where countries may face very different demographic realities at the same time.
Some will need more schools and jobs for young populations. Others will need more caregivers, medical services and retirement support for older populations.
Those differences could influence economies and government policy for decades.
A Generation That Changed America
For America’s Baby Boomers, the latest numbers represent another chapter in the story of a generation that has influenced the country for decades.
They helped shape American culture, workplaces, politics, music and family life.
Now they are helping reshape what aging itself looks like.
The challenge ahead will be ensuring that longer lives are accompanied by financial security, good health care and opportunities to remain connected to family and community.
One thing is certain: the world is getting older, and that transformation is only beginning.
