How Fashion Can Grow When the Global Population Starts Shrinking

Fashion is a business that’s long seen growth as the be all, end all — but the style sector might need to start finding a new path forward.

Fertility rates around the world have slowed dramatically in recent decades — many generations are having fewer children — and are now expected to fall below replacement level before 2050, resulting in global population declines.

The long-term implications for fashion are vast.

As the world transitions to a place with fewer people, retail will face a scramble for market share, an increasing international push and other changes that could reorder the industry in unforeseen ways.

Martin Lindstrom, a consultant who specializes in business transformation and branding, said brands will need to get back to their roots and produce styles that last and that consumers want to invest in, while also reducing their ecological impact.

“Fashion has to go from cost to an investment,” Lindstrom said. “And if they don’t manage to do that soon — it is such a sensitive industry now — I don’t think the fashion houses can keep it alive.”

In many ways, the industry isn’t suited to face the shift. Not only is a shrinking population a big and all-encompassing issue, it’s one today’s chief executive officers and boards may choose to ignore. People historically do a poor job of planning for far-off and complicated problems. See: climate change.

And right now, brands are seeking growth at all levels. Billion-dollar brands aren’t often content to stay that way — they want to expand to $3 billion or $5 billion. Even flat sales are tantamount to failure in the eyes of Wall Street.

Steady state is not a thing fashion or business generally does well. It hasn’t had to — yet.

Since the 1950s, the global population has ballooned from 2.5 billion to more than 8 billion today, according to the United Nations.

Growing a business has required, more than anything else, the ability to ride that wave and bring in more shoppers. But soon, the wave will hit shore.

Researchers raised a warning flag last month in The Lancet medical journal, noting that global fertility rates have fallen from 4.84 percent in 1950 to 2.23 percent in 2021 — just above the 2.1 percent needed to keep the population stable.

By 2050, the fertility rate is expected to fall to 1.83 percent, with the lowest-income countries accounting for an increasing percentage of births. “We broadly found that human civilization is rapidly converging on a sustained low-fertility reality,” the researchers said in Lancet.
