The Average Billionaire In This Country Is 83.7 Years Old, And Other Countries With The Oldest 1%

While startup culture is fueling a new wave of young billionaires, many countries are seeing their billionaire class age into their seventies, eighties, and even nineties. In places like Argentina, Chile, and Japan, the average billionaire is well past traditional retirement age. While young billionaires can be a sign of disruption and innovation, old billionaires can reflect a culture of economic stagnancy and reveal just how enduring old money can be in certain countries.

The countries with the oldest billionaires tend to have wealth concentrated in traditional industries like mining, real estate, and logistics. In Argentina, where the average billionaire is over 83 years old, many of the richest individuals built their fortunes decades ago and continue to maintain influence in a volatile economic environment. Similarly, in Chile, wealth is still dominated by a small group of families tied to the mining sector. A closer look at the data reveals the countries with the oldest billionaires, and what their ages say about the broader economy.

To determine the countries with the oldest billionaires, 24/7 Wall St. reviewed the latest data from the Forbes Real Time Billionaires List.
