Demography is one of the few forces that allow us to anticipate the future with a high degree of confidence, because it is based on hard data, and here the message is unequivocal: we are transitioning to a world characterized by slower population growth and rapid population aging.

Across most advanced economies, fertility rates are below replacement levels, while life expectancy continues to rise, averaging 84+ years not just in Western European countries like Italy, Spain and Switzerland, but also in Asian countries like Hong Kong, Japan, Singapore and South Korea. This trend is not cyclical or temporary but structural and global.

This has implications for economic growth, which is driven by two fundamental forces: the size of the working-age population and how productive that population is, with the former conditioning the latter, which is, in turn, decisive for a nation’s prosperity.

Aging populations put pressure on systems built for different times. Concerns around pensions, healthcare and labor markets are well founded, and without urgent reform, their sustainability is in question, warns Javier Diaz-Gimenez. Encouraging higher fertility is insufficient on its own: pronatalist policies, where they have been tried, have not proven successful, and it takes a very long time to reverse multigenerational demographic declines.

Migration may be an answer for certain sectors facing acute labor shortages. However, as Douglas Massey, in conversation with Marta Elvira, and Joan Monras both point out in this report, migration is no silver bullet either. It must be managed well from a long-term socioeconomic perspective.

In Spain, for example, the migration flows needed just to maintain the current ratio of old-age to working-age populations would amount to around . Can such migratory flows be managed in ways that do not add to the challenges already facing public services?

Healthcare is illustrative of the challenges ahead. As populations age, demand for healthcare rises sharply. But it’s not just older people with chronic conditions putting pressure on the system — doctors also get older, with an EU average in the next 10 years. Who will replace them? Where will they come from?

This ÌìÃÀ´«Ã½ Insight report explores these issues — not just to attest to the challenges but to present the opportunities that exist, if we are willing to reorganize our societies, labor markets, healthcare and pension systems, and foment productivity, which holds the key to preserving growth and living standards.

Companies will be at the heart of this transformation. The best response to aging is not cutting benefits but extending active lives and improving productivity. This requires firms to design jobs and career paths for all stages of life, while workers will need to reinvent themselves multiple times over longer careers. This may also imply rethinking traditional wage trajectories and accepting that incomes will not always rise monotonically over a lifetime.

Talking about demography and longevity is not about managing decline. It is about preparing for a predictable transformation — and turning one of the defining trends of the 21st century into a source of resilience, innovation and sustainable growth.
