Valentine’s Day has roses and a table for two. But what if there’s no one across the table?

In the early 1990s, students at China’s Nanjing University reportedly came up with an answer: November 11. Written 11/11, the date looks like four lonely ones standing side by side. A day to celebrate being single. Perhaps even enjoy it.

Then the retailers showed up.

In 2009, Alibaba turned Singles Day into an online shopping promotion. Within a decade, it had become one of the world’s largest shopping events. In 2021, Alibaba reported more than 540 billion yuan (about $84.5 billion) in gross merchandise value during its 11-day Singles Day festival.

Those sales weren’t all purchases for one. The holiday had outgrown its origins. You no longer need to be single to shop on Singles Day, any more than you need to be Irish to celebrate St. Patrick’s Day.

Still, Singles Day caught on for a reason.

A Holiday With No One Else to Buy For

For generations, the consumer calendar has been organized around relationships.

Valentine’s Day celebrates romance. Mother’s Day celebrates Mom. Christmas celebrates practically everyone, including relatives you haven’t seen since last Christmas.

Singles Day offered something different. No spouse required. No one else to shop for. Just you.

You could celebrate yourself.

In China, there’s a word for this attitude: yueji, loosely translated as “pleasing oneself.”

It’s an increasingly visible part of consumer culture. From beauty products and fashion to travel and personal experiences, buying something simply because it makes you feel good has become an occasion in its own right.

Treating yourself no longer requires a special occasion. Sometimes, treating yourself is the reason.

The Demographics Behind Singles Day

Singles Day began as a joke, but the joke landed in a country where relationships and households were changing.

China’s 2020 census found that 25.4% of family households consisted of one person. The average household had shrunk from 3.96 people in 1990 to just 2.62 in 2020.

Marriage is happening later, and less often. Marriage registrations fell sharply in 2024 to 6.1 million couples, the lowest since 1980. They rebounded to 6.76 million in 2025, but remained roughly half their 2013 peak.

Here’s the contradiction. China’s government is encouraging more people to marry and have children. Meanwhile, the country’s biggest shopping festival began by celebrating those who hadn’t.

Of course, demographics alone didn’t create a shopping phenomenon. Online retail, discounts, and relentless promotion helped turn a campus joke into a retail-powered ritual.

But the cultural opening was there.

As I discussed in When 1 = 2: The Surprising Economics of Households of One, a household of one is an economy of its own.

Singles Day goes one step further. The individual has become an occasion for consumption.

Your Right Hand Says “Me”

Miley Cyrus had a 2023 hit, Flowers, about buying them for herself. She was 20 years behind the jewelry industry.

For much of the 20^th century, jewelry advertising relied on a familiar scene: a man handing a woman a small box. Romance supplied the moment.

In 2003, De Beers introduced its Women of the World, Raise Your Right Hand campaign, encouraging women to buy diamonds for themselves. Its message was clear and direct:

“Your left hand says ‘We.’ Your right hand says ‘Me.’”

A diamond. No proposal required.

By 2016, women were buying 31% of all women’s diamond jewelry in the United States for themselves, according to De Beers research.

The company’s research revealed another interesting twist. In the United States and Japan, women buying diamonds for themselves were more likely to be married. In China, they were more likely to be single.

Self-reward, it turns out, has no marital status. A woman might buy herself jewelry to celebrate a promotion, a new business, or surviving a particularly difficult Tuesday.

The occasion belongs to her. Singles Day didn’t invent that attitude. It gave self-reward a date on the calendar.

When Shopping Becomes a Ritual

We usually assume businesses follow demographic change. More people live alone, so companies sell smaller appliances. Women gain purchasing power, so luxury brands reconsider who walks through the door.

That’s true. But Singles Day shows the current running the other way.

Retailers took a college student joke about being without a significant other, added a checkout button, and turned it into an annual consumer ritual.

Rituals matter. They reflect and reinforce societal reality. They make a behavior visible, and even ordinary.

Valentine’s Day still has its place. But the next big occasion may not need anyone else to buy the flowers.

The United Kingdom has about 69 million people today. By 2100 it could have 44 million. Or 91 million.

Both numbers come from the same official source, the Office for National Statistics’ (ONS) latest population projections. Look at the chart above. Same country, same starting point. Change the assumptions about migration and fertility, and nearly 47 million people appear…or disappear.

I've spent decades telling audiences that, unlike economics or technology, demography is destiny. But destiny, it turns out, has a timeline.

I like a good metaphor. Think of demography as a river. Its course is shaped by forces already in motion, and we can generally map where it will flow. But dams and canals can still change where a river goes. The catch is time.

Over the next 10 or 20 years, most of the demographic future is already here. The workers, households, and customers who will define the markets of the 2030s and 2040s have largely been born. For any business deciding where to invest in people, products, or infrastructure, that future should already be inside the planning cycle.

Look 50 or 100 years out and the picture changes. Choices about migration, family, health, and how people live compound across generations. Very different countries become possible.

Even the ONS illustrates the point. In its previous projections, the UK's population kept growing until the 2090s. The new ones have it peaking in 2054 and then shrinking. Change the assumptions, and the long-run story flips.

Demography is both a short game and a long game. In the short game, we adapt to a future already in view. In the long game, what we decide now shapes the future that follows.

Here is the irony. The demographic future we can see most clearly is the one we can least change. The one we can change most is the one we can see least clearly.

Demography may be destiny. It helps to know which destiny you’re talking about.

Your watch thinks you slept poorly. Your ring agrees. You thought you were having a perfectly good morning. Then you notice your recovery score is down and wonder: Do I really feel okay?

Welcome to a health market that doesn’t require you to feel sick.

Gen Z and millennials make up about 36% of U.S. adults but account for roughly 41% of annual wellness spending, according to McKinsey’s Future of Wellness research. Its definition reaches well past medicine, into sleep, appearance and mindfulness.

The familiar question “What’s wrong?” now has company.

I feel fine. Could I feel better?

Rings track sleep. Watches estimate cardiovascular fitness, and sensors offer a running log on what lunch does to blood glucose. Biomarker panels, full-body scans and longevity clinics provide an up close look inside bodies that haven’t reported so much as a bellyache.

Some people arrive with symptoms. Others arrive with a credit card and a suspicion that “fine” leaves room for improvement. Some treat it like a leaderboard: How do I get my numbers up?

Why Younger Adults Invest in Feeling Better

Younger adults grew up surrounded by scores: steps, followers, credit ratings, screen time. A sleep score is just one more. That doesn’t mean they feel invincible.

McKinsey points to reported burnout and a steady stream of wellness content on social media as possible explanations for their interest. A person buying better sleep may simply be trying to get through the week, not plotting a 100th birthday party decades away.

The horizon matters too. At 35, strength and metabolic health can support decades of work and family life still ahead. You don’t have to call yourself a biohacker to want more good years.

The economist Michael Grossman described health as a form of capital more than half a century ago. We draw it down, and we can build it back up. Today, that capital has a balance statement. It vibrates on your wrist, often several times a day.

The ambition shifts across life. Someone in their 30s may want more energy after work. Someone in their 70s may want to keep hiking, or simply have the stamina to chase a 5-year-old grandchild. Both are investing in capacity for something they want to do.

The Expanding Household Health Budget

The spending goes well beyond gadgets. A November 2025 KFF poll found that current GLP-1 use was highest among adults ages 50 to 64, and that 27% of insured users had paid the full cost themselves. These drugs treat conditions including diabetes and obesity, so paying cash can reflect a coverage gap as much as a consumer choice. Either way, it’s a new monthly bill, sitting next to the electric bill and Netflix.

Households have long paid for gyms and supplements. Now their health budgets reach into territory once largely confined to clinics: diagnostics and the work of making sense of the results. Was that shadow on the scan just a shadow?

Next to premiums and copays sit the trainer, the wearable subscription and the test insurance won’t cover. Those purchases compete with vacations, home repairs, even retirement savings, and in a household of one, there’s no second income to absorb them. They also demand time. A gym membership takes seconds to buy. Using it requires getting up on a cold morning and rearranging Tuesday.

3 Health Portfolios, 1 Question

In my recent Barron’s piece, and in a companion peer-reviewed paper forthcoming in Retirement Management Journal, I proposed thinking about health investments as three portfolios with different jobs.

A preventive portfolio maintains the baseline through exercise, sleep, vaccinations and screenings. It’s the “just keep me well” investment.

A performance portfolio seeks capacity beyond the typical baseline for one’s age, through training, nutrition and the technologies that guide them. This is where much of the emerging longevity market makes its pitch.

A protective portfolio addresses illness and its consequences, from treatment and rehabilitation to the support needed to live well with a condition. It’s the one most of us picture when we think about health.

The boundaries blur. Strength training can serve all three. What matters is the question underneath: What do I expect this investment to help me do?

That question applies to time as much as money. An expensive device may contribute less than a daily walk. A test may change a treatment decision, or simply supply another number to worry about, leading to, you guessed it, another test.

What Health Consumers Want Their Money to Do

The demographic change is in when people enter the market and what they expect from it. Younger consumers don’t have to wait to be sick to become customers. Older consumers may be managing a condition while also pursuing greater strength or mobility.

Age alone tells a company little about the ambition behind a purchase. A 35-year-old and a 65-year-old may want the same outcome, with different starting points.

Consumers now arrive with data and purchases already in hand. A clinician may be asked to interpret numbers collected elsewhere. A fitness coach may need to explain why a client feels stronger while their wearable says otherwise. A technology company faces the question its dashboard leaves unanswered: What should I do with this?

Employers are not simply bystanders. Employees’ out-of-pocket purchases can reveal demand that the benefits package may miss.

Some purchases will prove useful: a nudge that gets someone walking, an early warning worth acting on. Others will deliver anxiety, or a drawer full of well-intentioned gadgets. Evidence has to earn its place next to enthusiasm.

“I feel fine” once helped end a healthcare conversation. Increasingly, the conversation starts with a buzz on the wrist.

In December 2021, Toyota announced a $1.29 billion battery plant in North Carolina. By 2025, the commitment had grown to nearly $14 billion, production had begun, and more capacity was planned through 2030.

Factories are long bets. Toyota’s Kentucky plant has been running since 1988. Its Long Beach operation has passed the half-century mark. The North Carolina plant could still be producing batteries in 2050. Perhaps well beyond.

Toyota is headquartered in Japan, one of the oldest societies on earth. Its new plant sits in the United States, where population aging is projected to be more gradual. Demographics alone don’t explain the decision. Markets, costs, technology, trade policy, and supply chains all matter.

But the contrast raises a question every manufacturer and investor should ask: What will the population look like when today’s factories reach their prime production years?

Same Direction, Different Speeds

Demographic change is usually told as one story. Populations are aging. Birth rates are falling. Workforces are shrinking.

True. But incomplete. The speed of change varies enormously. So does where each country begins.

Using the UN’s World Population Prospects 2024, I compared 20 major manufacturing economies from 2025 to 2050 on a simple measure: people ages 20–64 for every person 65 or older. It isn’t a forecast of labor shortages. It describes the demographic ground a labor market stands on, and how fast that ground is shifting.

All 20 ratios decline. Not equally.

South Korea falls from about 3.2 working-age adults per older resident to 1.3, a drop of nearly 61%. China goes from 4.3 to 1.8, nearly 58%. The United States slides from 3.2 to 2.4, about 24%. That gentler American slope partly reflects assumptions about continued immigration. Demographic projections, it turns out, can depend on political decisions.

Now look at starting points. Japan is already at 1.8, heading to 1.3. A decline of about 30%, comparatively gentle. Yet Japan already struggles to staff its factories, hospitals, and construction sites.

Saudi Arabia presents almost the opposite picture. It starts at roughly 21.6, reflecting a much younger population that includes a large foreign workforce, and falls to 8.0 by 2050. A 63% drop. Even then, it will have far more working-age adults per older resident than Japan has today.

A country can be old and changing slowly. Another can be young and changing fast. For a company committing billions to a facility that will run for decades, both the starting point and the speed matter.

Moving Factories, Not the Clock

For a decade, companies have been rethinking where they make things. Rising costs in China, geopolitical tensions, tariffs, and fragile supply chains have pushed manufacturers to consider India, Mexico, and Indonesia.

The catch: all three, though younger than many established manufacturing economies, fall in the faster-changing half of the 20.

India has about 8.1 working-age adults per older resident, against China’s 4.3. By 2050, India’s ratio is projected at about 4.2, roughly where China stands today. India’s working-age population is still projected to grow, so a falling ratio doesn’t mean fewer potential workers. It does mean the ground will shift under any factory built there today.

Relocating a factory can reduce geopolitical risk. It doesn’t relocate you out of demographic change.

Automation helps. South Korea, Japan, and Germany, all facing demographic pressures, have long been leaders in industrial robotics. Add artificial intelligence (yes, I had to get AI in here), and the labor math shifts again.

But robots don’t install themselves. Factories need engineers, technicians, electricians, and skilled tradespeople. So do the new hospitals, healthcare facilities, and senior housing developments being built down the road. An aging society doesn’t just put pressure on the supply of workers. It creates new demand for the very ones factories need.

And the timelines don’t match. A plant takes years to build. A skilled workforce can take longer to develop.

Time Is Demographic Capital

Demographic projections can’t tell a CEO where to build the next factory. They can reveal what conventional investment analysis may miss: how much the population beneath today’s assumptions will change over the life of the asset.

Every long-lived investment carries an implicit demographic bet. Boards scrutinize the cost of capital and the tariff schedule. But how often do they stress-test the population a plant will depend on in 2045?

Demographics offer something unusual in long-range planning: a substantial degree of visibility. Most of the people who will work, retire, and need care in 2050 have already been born.

The advantage won’t necessarily go to whoever has the youngest workforce today. It may go to those who make the best use of demographic time: matching automation to changing labor conditions, building skills pipelines years ahead of need, and weighing a site’s future as carefully as its current costs.

Toyota’s North Carolina plant could still be running when today’s kindergartners are old enough to work there. They’re already born. They’re already counted.

The question is whether anyone in the boardroom counted them.

Note on Data: United Nations, World Population Prospects 2024, medium variant. Ratios are people ages 20–64 per person age 65 or older. Percentage changes are calculated from unrounded population estimates and projections.

Tomorrow morning, millions of people will follow a familiar ritual. Grab a coffee, drop some bread into the toaster. Maybe a bagel. Perhaps a Pop-Tart. Then get on with the day.

We don’t often think of a toaster as part of a home’s infrastructure. But it is. One toaster can serve two people, four people, even an entire family.

Now, here’s a question. How can one toaster become two without adding a single person?

The answer is hiding in one of the most significant demographic changes happening around the world.

More people are living alone.

Two people sharing a home need only one toaster. When those same people establish separate households, suddenly there are two kitchens, two refrigerators, and potentially two toasters.

The population hasn’t changed. But the economics of the population have.

Solo Living Is Changing the Consumer Market

Living alone is hardly new. What’s changing is how common it has become.

According to the U.S. Census Bureau, America had 39.7 million one-person households in 2025. That’s ~30% of all households, compared with just 20% in 1975.

In Canada, one-person households became the country’s most common household arrangement in 2016. By 2021, they represented 29.3% of households.

Across the European Union, the number of single-adult households without children increased nearly 20% in just the last decade, while the total number of households grew just 6%. That’s more than three times the overall growth rate.

This is not simply a story about older people living alone. Young professionals, people delaying marriage, divorced adults, and people who simply prefer living independently are all part of a changing household landscape.

Here’s the thing: the implications reach far beyond the breakfast table.

Japan’s Demographic Paradox: Fewer People, More Households

Japan has been a favorite example of what happens when a country’s population shrinks. Fewer people, fewer consumers, presumably smaller markets. Except the arithmetic isn’t quite that simple.

Between 2015 and 2020, Japan’s population declined by nearly one million people. Yet the country added about 2.4 million private households. That’s not a forecast. It actually happened.

According to Japan’s Statistics Bureau, by 2020, 38.1% of Japanese private households were single-person households. The average household size had fallen to just 2.21.

Think about that for a moment. Japan had fewer people but more households.

A company looking only at population projections might see a shrinking market. A company examining household formation might see something quite different.

Both could be looking at accurate demographic data. Only one company might be asking the right question.

More Households, More Products

Look around your home. You’ll find a refrigerator, stove, microwave, washing machine, television, furniture, lamps, and a closet filled with Swiffers, brooms, and enough cleaning products to tackle almost anything.

Most households don’t need one of everything for every person living there.

Four people can share a refrigerator. Two can share a washing machine. An entire family can survive on one toaster, even if they occasionally argue over whose bagel goes in first.

But when one household becomes two, the number of people hasn’t necessarily changed. The number of homes to equip has. And this begins with the homes themselves.

More households can mean demand for more homes, condos, apartments, and the related number of kitchens, bathrooms, utility connections, and the infrastructure that supports them.

The implications extend from real estate development and construction to appliance manufacturing, utilities, retail, and consumer goods.

Of course, two households don’t necessarily purchase twice as much of everything. But products that were once shared may now be needed in two different places.

That’s a very different way of calculating potential market demand.

One-Person Households Don’t Mean One-Size-Fits-All

There’s another twist. Two refrigerators don’t necessarily mean two Sub-Zeros.

Perhaps one household wants a Sub-Zero and the other a modest single-door refrigerator. Or perhaps both want something entirely different.

The point isn’t simply that the number of potential purchases changes. The variety of products people want may change as well.

Housing is one example. Living alone doesn’t necessarily mean living small. One person might want a downtown apartment. Another might want a small suburban home. Still another might prefer a large house with room for guests, hobbies, or a home office.

The same applies inside the home. Different households may want appliances with varying capacities, furniture designed for different spaces, and products that offer different combinations of convenience, performance, and price.

Even Pop-Tarts aren’t immune. A household of five and a household of one may buy the same product, but they may prefer different package sizes, quantities, or shopping arrangements.

From the house itself to what’s inside the pantry, changing household composition can reshape both the number and the kinds of products a market demands.

The Market Forecasting Blind Spot: People vs. Households

Businesses spend considerable time studying population forecasts. How many people will live in a region, in a country? Will the population grow or decline? Where will consumers be concentrated? How old will they be?

All reasonable questions. But population is only part of the story.

A population of ten million people living in four million households represents a different market from ten million people living in five million households.

Same population. One million more households. That is potentially more front doors, more kitchens, more refrigerators, more toasters, and a greater variety of products to meet different household needs.

For manufacturers, developers, retailers, and investors, that difference matters.

Demographic change doesn’t always announce itself with a population boom or bust. Sometimes it arrives quietly, one new front door at a time.

The next time a market forecast lands on the desk of a CEO, investor, developer, or board director, there’s a question worth asking.

What happens to your market forecast when you stop counting people and start counting households?

It is college application season.

Tonight, somewhere, a high school senior and her parents sit at a kitchen table with a laptop open, comparing choices. Four years at a university. Two years at a community college. A certificate. An apprenticeship. A job that starts Monday.

They are weighing time, tuition, debt, and earnings. How much will it cost? How long before it pays off? Will the credential lead anywhere? Why spend four years preparing to work if an employer will pay you to learn now?

Multiply that conversation by several million families, and the problem higher education calls the “demographic cliff” becomes an employer’s problem too.

Fewer Graduates, Same Pool

The Western Interstate Commission for Higher Education projects that the number of U.S. high school graduates peaked in 2025 and will fall 13% by 2041. Thirty-eight states will have fewer graduates in 2041 than in 2023. The reason is simple: fewer children were born eighteen years earlier.

A smaller graduating class does not mean an equally smaller workforce. Immigration, labor force participation, technology and older workers staying on the job all matter. But colleges and employers recruit from the same generation, and that generation is shrinking. Colleges are counting empty seats now. Employers may be counting unfilled jobs next.

Students Want Education, But They Question the Price

This is not an obituary for college. Most current and prospective students still believe higher education is worth it. They are less convinced about what it costs. In a Gallup–Lumina Foundation survey, only 18% said four-year colleges charge a fair price.

There appears to be growing interest in alternative pathways. Enrollment in community colleges is up. They enrolled 5.8 million students in spring 2026, 5.2% more than in spring 2021. Undergraduate certificate enrollment grew 10.2% in a single year, far faster than associate or bachelor’s degree enrollment.

The four-year degree is not disappearing. But shorter, potentially more employment-focused pathways are attracting growing interest. For the student at the kitchen table, the question is shifting from “education or work?” to “why do they have to be separate?”

The End of “You Educate Them, We’ll Employ Them”

For generations, American employers have relied on an education system they did not have to build. Families raised children. Taxpayers funded schools. Students paid tuition. Colleges educated them. Employers hired from the result.

Companies trained workers, funded apprenticeships and partnered with schools. But the basic deal held: You educate them. We’ll employ them.

Demographics are making that unspoken contract harder to keep. When workers are plentiful, employers ask, “Who has the skills we need?” When workers are scarce, the question becomes, “How do we develop the people we need?”

Employers will have to become co-producers of human capital, not just consumers of it. The remaining question is how early, how deeply, and how directly they get involved.

Michigan Is Reading the Curve

I recently had the privilege of speaking with Business Leaders for Michigan, a group of leading CEOs and board members representing the state’s automotive, education, financial services, healthcare, retail, sports, and manufacturing industries.

I came away impressed. These are accomplished business leaders who could focus exclusively on their own companies and industries. Instead, they are investing their time, influence, and resources in Michigan’s future. Many are catalyzing Detroit’s continued renaissance. They recognize that a company’s future depends on more than its balance sheet. It also depends on the strength of the surrounding communities, institutions, and people.

They have reason to look ahead. Michigan is one of five large states, along with California, Illinois, New York, and Pennsylvania, expected to account for about three-quarters of the national decline in high school graduates through 2041.

Their strategy, Michigan in a New Era, calls for transforming the state’s education system and building stronger connections among schools, apprenticeships, colleges, and employers.

What’s compelling is that these leaders are treating education not simply as a public responsibility, but as essential infrastructure for economic competitiveness.

That is an important distinction. It moves beyond employers advising educators on skills or writing checks. It envisions businesses working alongside schools and colleges to combine learning and earning: paid apprenticeships, work-based learning, industry expertise in classrooms, tuition support, shorter credentials and clearer routes from school to a job.

I left Michigan wondering whether these leaders signal an early shift in the American business-education partnership.

They are not simply asking where their future workforce will come from. They are helping shape the system that will develop it.

Tomorrow’s Workforce Has Already Been Born

Companies make ten-year plans for factories, technology, markets and capital. Their workforce plans often assume the right people will be there when those investments come online.

Demographics limit what money can do about that. Training changes skills. Immigration adds workers. Technology, currently AI, replaces some tasks. Older employees can stay longer. But most of the people businesses will depend on in the 2030s have already been born. Employers can still influence how those people learn, gain experience, and enter the workforce.

For much of the traditional college-to-career pathway, education came first, and employment followed. Increasingly, the two will happen together, through partnerships between institutions that once operated at arm’s length. That sequence is giving way to simultaneous learning and working, through partnerships between institutions that used to operate at arm’s length.

Government and educators still have central roles. But workforce development can no longer happen exclusively somewhere upstream from employers. It is infrastructure they must help build. Not as philanthropy. Not as an employee benefit. But because they need someone to show up for work.

Living longer is generally described as gaining more years. True, but incomplete. It also exposes us to more complexity.

More years also mean more time for the world around us to change. Technologies emerge and disappear. Institutions evolve. Jobs and industries are transformed. Financial products multiply. Healthcare becomes more capable and more complicated. Families change shape. New risks emerge. New choices become possible.

And, of course, we change too.

We become parents, caregivers, patients, managers, retirees, widows, grandparents, and sometimes students again. Our health changes. Our incomes change. Where and how we live may change. The people who depend on us change, as do the people we depend on.

Longer life means greater exposure to both kinds of change. That may be creating a personal challenge and business opportunity we have only begun to recognize.

Longevity Is Changing the Entire Life Course

Much of today’s longevity conversation focuses on older age. But the consequences of longer lives don’t wait until retirement, age 65, 75, or some other milestone birthday. The impact of longer life ripples across the entire life course.

Education no longer necessarily ends in our early twenties. Careers may contain multiple chapters, with new technologies demanding repeated periods of reskilling. Parenting can overlap with caring for older parents. Retirement may involve several transitions rather than one departure from work. What we need from home may change as the lives we live change.

Consider the 45-year-old managing a team at work, two teenagers at home, and a mother who suddenly needs help getting to the doctor. Or the 68-year-old who is still working, learning another generation of workplace technology, and beginning to make decisions about what comes next. Or the vibrant 85-year-old who must work harder to maintain the life they want to live.

One person may simultaneously be an employee, caregiver, parent, patient, investor, and homeowner.

Organizations tend to meet us with a product, service, or solution for one version of us at a time. The irony is that we live all our roles at once.

Complexity Often Lies Between the Transactions

I think of this emerging challenge as a “Complexity Economy.”

Someone may have more information than ever and still be less certain about what to do. She may have multiple products intended to protect her future but no clear picture of how they work together. A technology may promise greater capability while requiring her to learn yet another system. A family facing a major transition may discover that the services they need sit across professionals and institutions that were never designed to work together.

There may be no shortage of information, products, services, or expertise. The complexity lies in how to put them together across one longer, coherent life.

Businesses have become remarkably good at making individual products, services, and transactions easier. The harder problem may now lie between them.

Here is the uncomfortable part: every company involved may be doing its job well.

A product works as promised. A transaction is faster. More choices offer greater personalization. Better information is available. More experts are there to help.

And still, a person’s life can be harder to navigate. Complexity can grow even while every individual part of a system is getting better.

Think of a twist puzzle. Every piece works. Move one, and the relationships among the others change. There is no single piece to fix. The challenge is navigating the whole.

Most organizations are built around discrete products, functions, transactions, and services. People experience complexity across lives.

Four Business Capabilities for the Complexity Economy

In a world where living longer is the new norm, greater exposure to change and related complexity is also the new normal.

So what does an organization need to be good at in a world like this? How much complexity can organizations reasonably continue to leave for people to manage alone?

From the person’s point of view, at least four capabilities are emerging.

• Curate information. Information and choice are abundant. Attention and the ability to determine what matters are not. Value increasingly comes from helping people distinguish signal from noise and translate information into action.

• Design experiences. Making one transaction easy is different from making a complicated journey understandable. Decisions connect to other decisions, often across domains and organizational boundaries. What matters is how well those pieces work together from the person’s perspective.

• Extend capability. Technology should do more than automate transactions. Its greater value may be helping people do what they could not easily do alone: understand choices, remember, anticipate, coordinate, act with greater confidence, and often live with greater safety.

• Cultivate trust. Complexity requires us to rely on experts, institutions, technologies, and recommendations we cannot fully evaluate ourselves. Trust becomes more valuable, not less. The question is not simply whether an organization can complete today’s transaction or deliver a service. It is whether it has earned the right to be relied upon tomorrow.

These are unlikely to be the only capabilities that matter. But they have something important in common. Each reduces the burden of complexity the individual must navigate alone.

Delivering these capabilities may require organizations to become something more than they are today. Not necessarily bigger, but broader in how they understand the lives of the people they serve.

From Complexity to Confidence

What do these capabilities ultimately provide people? Perhaps it is confidence.

Not confidence that life will become simple or that uncertainty will disappear. Instead:

Confidence that I understand enough to make a decision. That I know what comes next. That I have the capability to act. And that when I cannot manage everything myself, I know whom or what I can rely upon.

That kind of confidence may become increasingly valuable in a longer life.

The goal is not to eliminate complexity. Much of it cannot, and perhaps should not, be eliminated. More choices, technologies, and possibilities can make lives richer as well as harder to navigate.

The opportunity is to help people navigate that complexity with greater confidence.

What should we curate for people, and what should remain theirs to decide? Where should technology remove effort, and where should it enable greater capability? How do we create a coherent experience when someone’s problem crosses domains and organizations? What must an organization do today to earn the right to be trusted tomorrow?

These are not simply questions about engaging people in the marketplace.

They may be questions about what organizations will need to become in a society where people are living longer and living differently.

The United States isn’t simply getting older. We are having fewer children and having them later, living in smaller and different households, and relying on family in different ways. Those changes are beginning to reshape the institutions built around assumptions of how most Americans once lived.

Earlier this month, a hospital in upstate New York stopped delivering babies. This might otherwise be a local story. I think it is a larger signal.

On September 3, Newark-Wayne Community Hospital suspended inpatient labor and delivery, newborn nursery and postpartum services. The hospital cited multiple familiar challenges: difficulty staffing around the clock, fewer births over time, and families choosing regional hospitals with advanced resources.

There Is Something Happening Here

Newark-Wayne is one hospital. National numbers suggest something larger. A new University of Minnesota analysis found 718 U.S. hospitals lost obstetric services between 2010 and 2024. 67 closed obstetric services in 2024 alone. By 2024, nearly half of American hospitals offered none. This is not just a rural issue: 42 of those 67 recent losses were urban.

Pediatric care shows a related pattern. A JAMA Pediatrics study found pediatric inpatient units declined nearly 30% between 2008 and 2022, and pediatric beds almost 20%. In sharp contrast, there was only a 4.4% decline in adult units. Care is increasingly consolidating into fewer, larger, more specialized centers.

Fewer Babies, Later

The U.S. total fertility rate reached 1.60 births per woman in 2024. That is well below the roughly 2.1 births per woman generally considered replacement-level fertility in developed countries. CBO projects it will fall to about 1.53 and remain near that level for years. But the timing is shifting too: CDC data show fertility among women 35–39 rose 5% from 2015–2024, and among women 40 and older, 24%.

That’s a more complex planning challenge than “fewer maternity beds.” Lower volume may make obstetric capability unsustainable in many places, while having children later in life may increase demand for more sophisticated obstetric and neonatal care to manage older mothers, who are more likely to have complex childbirths, in fewer places. The future may need fewer maternity units, but not simpler ones. Pediatrics may be following a similar path: fewer children overall, but more concentrated expertise.

This isn’t a story about less demand. That’s an incomplete observation. It’s about different demand, in different places, requiring different capabilities.

Age Alone Doesn’t Tell Hospitals Or Anyone Else How People Live

Imagine two 82-year-olds with the same diagnosis. Their disease state may be the same, but how they live might be radically different.

One has a spouse and three adult children nearby to help with appointments, meals, and medications. The other 82-year-old lives alone; an only child is 1,000 miles away and works full-time.

Same age, same diagnosis. Each has very different discharge risks.

Households are smaller. More people live alone. Families are dispersed. Those are demographic facts too, and they help determine whether a patient recovers at home with someone ensuring medications are taken and the appropriate meals are prepared or is readmitted to the hospital two weeks later.

Demographics Are More Than Numbers

In research I conducted earlier this year with 118 healthcare board and C-suite leaders, 38% said demographics were formally incorporated into strategic planning, and another 41% considered them informally. Yet only 28% said demographics were regularly incorporated into workforce planning.

That gap matters because “demographics” too often means counting people — particularly how many are over the iconic, seemingly magical age of 65. But demographics also means asking when people have children, how households are structured, who lives alone, where families live, and who is actually available to provide care.

A CEO sees a staffing shortage. A CFO sees reimbursement pressure. A discharge planner sees a patient with no one at home

Same transformational force, demographic change, but different symptoms, too often addressed incrementally without recognizing the larger source of change.

When Demographics Become Infrastructure

Demographic change is gradual. Decisions about organizational infrastructure, scale, and capacity aren’t.

A hospital doesn’t close 3% of a maternity ward when births decline by 3%. It operates until some combination of volume, staffing, and cost crosses a threshold. Then a sense of urgency sets in at a board meeting or an operations review, and suddenly an entire capability can disappear.

Rebuilding it takes far more than reopening a room: it takes clinicians, equipment, referral relationships, and enough volume to sustain them.

That’s why a maternity department’s closure in upstate New York is worth watching. It may be one of the first signs of a broader mismatch: organizations built on assumptions about how people live are still operating on those assumptions even as the population has changed.

A Question Every Industry and Organization Must Ask

This is not just a healthcare issue. Financial services may still assume a relatively predictable life course, with a transition from work to retirement and family available to help. Higher education remains heavily invested in concentrating education into four years near the beginning of adult life, even as careers require learning and reinvention across decades. Much of our housing stock was designed around household and family structures that increasingly describe fewer of the people who will occupy it.

Different industries. Different infrastructure. The same strategic question:

Are we planning and investing for a changing population — or for a population that no longer exists?

And perhaps the more difficult question:

What assumptions about how people live are still embedded in your organization’s operations, investments, and long-term strategy?

Most of us notice demographic change after its consequences have already arrived.

A maternity ward closes. A university discovers it has too many seats and too few students. An employer cannot find enough workers. A financial services company realizes that retirement no longer matches the life stage its products were designed to finance. A restaurant chain discovers that the customer it once knew so well has changed.

We tend to treat these as separate stories. I don’t.

As a social scientist, I have long been interested in the forces that shape how we live, work, consume, care, age, and make decisions. Demographics are among the most powerful of those forces, yet also among the easiest to underestimate.

Perhaps that is because demographic change rarely arrives with breaking-news urgency. Fertility declines slightly each year. People live longer. Households shrink. Marriage and parenthood occur later. More people live alone. Families are spread over greater distances. People move.

Then something happens.

A business model stops working. A school closes. A labor shortage becomes chronic. A hospital eliminates a service. A product designed for yesterday’s household loses relevance. Once-vibrant communities become ghost towns.

What looks sudden often wasn’t.

Demographic change is gradual. Its consequences often are not.

This is the territory of The Demographic Edge.

Demographics Are About More Than Numbers

Mention demographics and most people think numbers. Birth rates. Death rates. Migration. Age distributions. Household size.

Not incorrect, just incomplete.

Here on The Demographic Edge, I want to look beyond the numbers to how people actually live and what difference those changing lives might make.

When we marry. Whether we have children. Where family members live relative to one another. How long we work. Who provides care. Whether we live alone. What we buy. Where we move. What we expect from institutions. Who we trust or don’t trust. Even what we imagine a good life should look like.

Those patterns matter because assumptions about how people live become embedded in infrastructure, products, institutions, policies, and investment decisions.

They influence everything from where we build hospitals and homes to how we educate workers, finance retirement, and think about economic growth and national power. The assumptions may have made perfect sense when they were made. The question is whether they still do.

The Longevity Economy Was Only the Beginning

Much of my work has focused on longevity and what longer lives mean for business and society.

Longer lives change retirement, but they also change work, financial planning, caregiving, housing, transportation, consumption, and the demands we place on families and institutions. Retirement may now occupy a full one-third of adulthood, not simply the 15 or 20 years many institutions and individuals once planned around. That changes the calculus for individuals, families, and entire industries.

That work led me to a larger question: What happens when longer lives occur at the same time as smaller families, delayed marriage and parenthood, more solo living, new patterns of work, and rapidly changing technology?

That is no longer simply a story about aging. It is a story about how society itself is changing.

Longevity planning will remain part of what I explore here. So will retirement. They should. Longer lives are among the great demographic achievements—and opportunities—of our time.

But they are part of a much bigger picture.

Technology and Demographic Change Are Converging

Technology is not simply responding to demographic change. It is an independent force changing the same world at the same time.

Artificial intelligence is changing how people find information, make decisions, work, learn, shop, and increasingly care for themselves and others. Automation may change what labor shortages mean. Robotics may alter what independence looks like in later life. New reproductive technologies may change when and how people form families.

Now put those developments alongside longer lives, falling fertility, smaller households, migration, delayed life milestones, and changing family structures.

The interesting story is not any one of them. It is what happens where they converge—and, in some cases, outright collide.

A society with fewer potential family caregivers encounters technologies capable of performing some caregiving tasks. Longer working lives encounter AI just as employers are reconsidering the skills they need. The half-life of formal education becomes more significant just as working lives expand from 30 to 40 to 50-plus years. Smaller households encounter a housing stock designed for another era. Consumers with more years of life encounter institutions still organized around yesterday’s life course.

Here’s the thing.

Technology changes what is possible. Demographics change what is necessary. And people decide what is acceptable.

Small Signals Can Reveal Big Changes

This is why I am interested in signals. Not every important change begins with a government report or a CEO announcing a new strategy. Often it first appears as something that seems almost too small to matter.

A maternity unit closes in one community.

A supermarket shelf offers ten versions of something that once came in two.

A new housing model appears for a household that would have been unusual a generation ago.

An employer quietly changes a benefit because the families of its workers have changed.

A technology begins performing a task once handled by a family member.

Individually, these are easy to file under healthcare news, consumer behavior, real estate, workplace policy, or technology. But what if they are connected?

That is when seemingly insignificant observations become interesting. Together, they may signal something much bigger.

The Demographic Edge looks for seemingly unrelated signals and asks what they may be telling us together.

What Comes Next?

I have spent decades researching these questions at MIT, working with organizations across industries around the world, and, perhaps most importantly, listening to people describe how their lives are actually changing.

This publication gives me room to range more widely.

Some signals will turn out to be noise. Others may reveal changes that are hiding in plain sight. The point is not to predict every turn in the future. Forecasts and models have their place, but they are only as useful as the assumptions behind them—and assumptions have a habit of outliving the realities that produced them.

The more useful task is to notice when the assumptions underlying our businesses, institutions, investments, and policies no longer match the lives people are actually living.

Demographics are sometimes described as destiny. On their own, they are not. But neither are they background scenery.

They create pressures, constraints, and possibilities. Technology creates new capabilities. Markets respond. Institutions adapt or don’t. People make choices.

The future emerges from the interaction. Seeing those forces earlier does not tell us exactly what will happen.

It gives us an edge in thinking about what might.

And that is the idea behind The Demographic Edge.

Because demographics don’t merely describe who we are. They help shape what comes next.
