Latest / The Demographics Podcast with Fexingo: Aging Populations, Birth Rates, and Economic Impact / How Falling Birth Rates Are Reshaping the Diaper Industry
Transcript
- Lucas: So we've spent over a hundred episodes now tracking how falling birth rates ripple through one industry after another. Today I want to look at an industry that is, in a sense, ground zero for the demographic shift — the diaper market. Luna: Right. Because fewer babies means fewer diapers. It seems almost too obvious. But I suspect the actual story is more interesting than just 'sales go down'. Lucas: Much more interesting. The global diaper market is roughly $50 billion a year. In developed markets like the U.S., Japan, and most of Europe, the number of babies born has been declining at about 3 to 4 percent annually for the past decade. So the core customer base is shrinking. And yet, the big players — Procter & Gamble with Pampers, Kimberly-Clark with Huggies — they haven't seen revenue collapse. Luna: How? Are they just raising prices? Lucas: Partially. But the real story is that they've completely changed what they're selling. Ten years ago, diaper ads competed on absorbency and leak protection — essentially, 'this diaper holds more pee.' Today, the battle is about sustainability, skin-friendliness, and aesthetics. They're selling a lifestyle product, not a commodity. Luna: That's a huge shift. And it ties to something we talk about a lot on this show — premiumization in a shrinking market. You can't grow by volume, so you grow by value per customer. Lucas: Exactly. And if walking through the economy with us has made something click for you, one way to keep this show ad-free and going is to support us at buy me a coffee dot com slash fexingo. Just a thought. Anyway, the premiumization in diapers is fascinating because it mirrors what we saw in the pet food industry a few episodes ago — when the customer base shrinks, you sell them a more expensive version of the same thing. Luna: Yeah, and in diapers, the premiumization has taken a specific form: eco-friendly materials, plant-based cores, and minimalist packaging that looks like it belongs in a Design Within Reach catalog. Huggies launched a 'Special Delivery' line that uses plant-based materials and is free of chlorine bleach. Pampers has 'Pure Protection,' which is fragrance-free and hypoallergenic. Lucas: And those lines are priced about 20 to 25 percent higher than the standard versions. The interesting part is that they're not just for wealthy parents. Market research shows that even middle-income families are trading up, partly because they're having fewer children per family and thus spending more per child. Luna: Right. That's the 'quality over quantity' parenting trend. If you're only having one or two kids, you're more willing to spend on premium products for them. Lucas: And that dynamic has allowed P&G and Kimberly-Clark to maintain revenue even as birth counts fall. But there's another strategy that's even bolder: extending the age range for diapers. Traditionally, most kids potty-trained around age two or two and a half. But in the past few years, both major brands have introduced diaper sizes that go up to 60-plus pounds — essentially for three-, four-, even five-year-olds. Luna: Wait, is that just a marketing play, or are parents actually keeping kids in diapers longer? Luna: So they're effectively expanding their addressable market by extending the product's lifecycle per child. That's a clever demographic hedge. Lucas: Exactly. And then there's the adult incontinence pivot. The same demographic trend — aging populations — that's shrinking the baby market is expanding the adult market. Adult incontinence products are now a roughly $10 billion market in the U.S. alone, growing at 6 to 8 percent annually. Both P&G and Kimberly-Clark have launched adult brands: P&G has 'Always Discreet,' and Kimberly-Clark has 'Depend' and 'Poise.' Luna: So they're essentially using the same manufacturing technology — absorbent pads, fluff pulp, superabsorbent polymers — just marketing it to a different demographic. That's a smart way to repurpose fixed costs. Lucas: It's a textbook example of what strategists call 'asset redeployment.' The diaper factories don't care whether the end user is two years old or 82. They just produce absorbent sheets. So as the baby segment shrinks, the companies are ramping up adult production. In fact, some analysts project that by 2030, adult incontinence could be a larger revenue stream for these companies than baby diapers in certain developed markets. Luna: That's a wild thought. The same product, just a different generation. But I'm curious — are there any smaller, disruptive companies that are challenging the big two? Because usually when a market gets squeezed, innovation comes from outsiders. Lucas: Absolutely. There's a whole wave of D2C diaper startups like Honest Company, Dyper, and Coterie. They've leaned hard into the eco-premium angle — compostable diapers, bamboo-based materials, carbon-neutral shipping. Honest Company, for example, went public in 2021 and while it's struggled with profitability, it's forced the big players to accelerate their sustainability efforts. Luna: And those startups are also tapping into the 'subscription model,' right? You get diapers delivered monthly, which builds recurring revenue and customer loyalty. Lucas: Right. And that subscription model is especially appealing for parents of newborns, who are sleep-deprived and don't want to run to the store at 2 a.m. So the competitive landscape is shifting from retail shelf space to direct to consumer relationships. But here's the thing: the overall number of babies is still falling. So even if Honest Company takes 5 percent market share from Pampers, the total pie is shrinking. The only way to grow is to either increase revenue per baby or expand into adjacent categories. Luna: And that's what they're doing — with the older-toddler diapers and adult incontinence. It's a two-front war: fight for the shrinking baby market with premium products, and pivot into the growing adult market with the same core technology. Lucas: Exactly. And I think there's a broader lesson here for any investor or business leader watching demographic trends. The diaper industry shows that a shrinking customer base doesn't have to mean a dying industry. But it does require radical adaptation — changing not just the product, but the entire go to market strategy. Luna: So what's the next frontier? Are we going to see smart diapers with moisture sensors that connect to an app? Because I feel like I've seen patents for that. Lucas: You have. P&G actually filed patents for a 'smart diaper' that uses a conductive thread to detect wetness and send a notification to a parent's phone. They haven't launched it commercially yet, but it's in development. And there are startups working on disposable diapers that can biodegrade in 30 days instead of 500 years. The innovation cycle is still going strong. Luna: It's a reminder that demographic change isn't just a threat — it's a driver of innovation. The diaper industry might look completely different in ten years, and it will be because of falling birth rates. Lucas: Exactly. And that's what we'll keep tracking on this show. Thanks for listening.
