About The Demographic Edge
Most of us notice demographic change after its consequences have already arrived.
A maternity ward closes. A university 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.
We tend to treat these as separate stories. I don’t.
The Demographic Edge explores the forces reshaping how we live, work, consume, care, age, and make decisions—and what seemingly unrelated signals may be telling us about what comes next.
Demographics are about more than numbers. Birth rates, longevity, migration, age distributions, and household size matter because they change how people actually live. And assumptions about how people live become embedded in businesses, infrastructure, products, policies, and investments.
The assumptions may have made perfect sense when they were made.
The question is whether they still do.
From Longer Lives to Changing Lives
Much of my work has focused on longevity and what longer lives mean for individuals, families, business, and society—including the longevity economy, retirement, longevity planning, caregiving, housing, transportation, and technology.
That work remains central here. But it has also led me to a larger question:
What happens when longer lives occur alongside smaller families, falling fertility, migration, more solo living, new patterns of work, and rapidly changing technology?
These forces are unfolding differently from Boston to Tokyo, Seoul to São Paulo, Lagos to London. Together they are reshaping markets, institutions, communities, families, and even economic and national power.
That is the larger territory of The Demographic Edge: looking for signals around the world and asking what they may be telling us about what comes next.
