There’s been plenty written about the rising wealth of the 1%, and a look at the list of the world’s billionaires drives home just how much wealth they have.

A look at the world’s wealthiest people shows a list dominated by men that skews older, not counting a certain social media pioneer.

Tne list, compiled by the Hurun Report, found 2,089 billionaires in 68 countries in 2015, up 222 over the previous year. The average age was 64, and their total wealth fell 1.5% to $6.7 trillion.

Still almost all of those on the top of the list did well in their investments this year as their wealth grew over the past year. Hooray for the wealth advisors who helped them out.

The U.S. had the most billionaires of any country with 537. China, with 430, is the only other country with more than 100.

The younger side of the list made strides. There are now 40 billionaires under age 40, up an amazing 16 over the past year.
