According to the latest Forbes data, a record-breaking 3,028 people on planet Earth are now billionaires. And as the number of billionaires grows, so does their age. The average billionaire is now 67.3 years old, a slight increase in age from recent years.

While the billionaire class is getting older, there are unique pockets of super young billionaires scattered around the world. In many cities, the average billionaire is under 60 years old, while in one unique seaside town the average billionaire is just 31 years old. Many of the youngest billionaires are heirs and heiresses to old money fortunes, while some billionaires under 50 are self-made tycoons. A closer look at the data reveals the cities with the youngest billionaires.

To determine the cities with the youngest billionaires, 24/7 Wall St. reviewed the latest data from the Forbes Real Time Billionaires List. Cities were ranked based on the average age of billionaires as of May 16, 2025 by city and country of residence. Supplemental data on the number of billionaires and total billionaire wealth is also aggregated from Forbes data. Only cities with at least three billionaires were considered.
