For decades, food and beverage growth ran on a simple engine: more people, more households, more units. In mature markets, that engine is slowing. The next phase of growth will come from relevance and value, not volume.
The Volume Assumption Is Breaking Down
The demographic base is shifting. More than a quarter of the world's population, 28 percent, now lives in one of 63 countries or areas where population has already peaked, including China, Russia, Japan and Germany. Two-thirds of the world's population live where fertility is below 2.1 children per woman. The UN projects that by the late 2070s, people aged 65 or older will number 2.2 billion, more than those under 18.[1]
Household structure is changing as well. Japan shows where this leads. In 2020, single-person households made up 38% of all Japanese households. That share is projected to reach 44.3% by 2050, even as total households fall from about 55.7 million to 52.6 million. Fewer, smaller households mean smaller baskets, different pack sizes and different meal occasions.[2]
The commercial data already reflects this. NIQ reports that global FMCG value grew 1.8% in the year to March 2026, while unit volume grew just 0.7%. The gap between the two is carried by price and mix. Companies planning for volume recovery are planning against the evidence.[3]
From Mass Propositions to Need-State Precision
Mass-market propositions assume a broad, similar consumer. Aging economies do not offer one.
Take "seniors" as a target. In Japan, 29.4% of the population is 65 or older, but only 5.6% is 85 or older. A healthy 66-year-old is still working, and a frail 86-year-old living alone has almost nothing in common as shoppers. One wants energy, protein, and social occasions. The other wants easy-to-open packs, softer textures, and single servings.[4]
Age is only one lens. The relevant unit is the need-state: the specific job a consumer wants a product to do at a specific moment. Teams that segment by need state, rather than by demographic label, can see where demand is growing even when the total is flat.
This changes how category leaders should read their data. Flat category volume can hide fast growth in two or three need states and steady decline in the rest. The averages tell you little.
Where Value Creation Is Coming From
Four levers keep appearing in markets where volume is capped.
Health. Consumers increasingly judge food and drink by what it does for them. McKinsey sizes the global wellness market at $1.8 trillion, and its 2025 research found that 84% of consumers now say wellness is a top priority in their lives.[5][6]
Functionality. Specific benefits are replacing general claims. McKinsey's 2025 research lists functional nutrition and gut health among its pockets of growth, noting that consumers want targeted health benefits from what they eat. It also flags cognitive health as underserved. [7]
Convenience. In a market tilting toward one-person homes, convenience means right-sized portions, ready-to-eat formats and easy handling. It is a design question, not a discount question.
Premium quality. Shoppers are cautious, but they pay for products they trust. NIQ found that clean-label products grew 7.5% in the US this year, ahead of 5.9% for US CPG overall. It also reports that 95% of consumers say trust is a key factor when choosing a brand.[8][9]
None of these levers work alone. A functional product that is hard to open, or a premium product sold in the wrong pack size, misses the need-state it was built for.
Questions Leadership Teams Should Ask
Before reprioritizing categories or markets, leadership teams should press on five questions:
- Which of our categories depend on population or household growth to hit plan, and what happens if that growth does not arrive?
- How much of our recent growth came from price and mix, and how much from real volume?
- Which need states are growing inside our flat categories, and do we hold credible positions in them?
- Do our pack sizes, formats, and channels fit smaller and older households?
- Which markets are demographically ahead of us, and what can we learn from them before we get there?
The last question matters most. Mature markets will not age on the same timeline, which means some are already living in the future others will face.
Learn From the Market That Got There First
Japan is the clearest test case for value-led growth under demographic pressure. Its companies have spent years working through the questions above, and the results offer practical lessons for any executive planning for slower population growth.
