The world's wealthiest people by age

Wealth, like age, can be relative — you really notice it in relation to other people.

So the folks at Wealth-X have compiled a list of the richest people of each decade, ranking the wealthiest people in their 20s all the way through their 90s.

Because the list gave equal representation to the affluent of all ages, titans of the tech industry, who skew younger, dominated the rankings. The five youngest people on the list came from that industry.

Snapchat's Evan Spiegel took top honors for the 20-somethings, while Facebook's Mark Zuckerberg won among 30-year-olds.

Former Microsoft magnate Bill Gates, of course, not only won his decade — the 60s — but was the richest overall.

Only one woman made the list: Liliane Bettencourt, the French L'Oreal heiress, who topped the list for those ages 90 and older.

Here is the full list of wealthiest people, determined by age bracket, and their respective net worth as of Nov. 20.
