Record temperatures, droughts, war, COVID, bans on movement and meeting…it’s been a witches’ brew of events. Is nature telling us that humans have overburdened the planet?

Not yet, says Amlan Roy, author of “Demographics Unravelled” and our guest on the latest episode of the New Money Review podcast.

The global population can still grow further without triggering more damage, says Roy: technological advances and better education could let us add 2bn more humans by 2050, he argues.

The study of human traits such as population numbers—demographics—is the single most important subject that no one pays attention to, says Roy, citing management guru Peter Drucker.

But when people do pay attention to demographics, most then miss the point, Roy says in the podcast.

That’s because we all tend to focus on a single statistic—age—only.

“An 80-year-old in Japan is different from an 80-year-old in Sweden, Italy, Greece or Germany,” says Roy, citing the five countries in the world with the oldest average population.

“Consumption is different in those countries, workers are different, education is different and institutions are different.”

We need to research and understand these broader traits of humans to see what drives economies and financial markets, Roy says in the podcast.

Roy, a former investment banker, is a research associate at the London School of Economics and a fellow at the Institute and Faculty of Actuaries.
