The 25 richest families in the world ranked – from the US’s Koch brothers to Hong Kong’s Kwok clan

From the richest families in America to the richest royals in Europe, high concentrations of wealth can be found all around the world.

In fact, there are 2,208 billionaire individuals across 72 countries for a combined total of US$9.1 trillion, according to Forbes. But what about the world's billionaire families?

Bloomberg ranked the top 25 families with the richest fortunes across the globe — together, they possess $1.1 trillion in wealth from retail industries, media conglomerates, agribusiness companies, tech giants, and more.

Bloomberg determined its ranking based on net worth figures from June 15, 2018. It didn't take into account first-generation fortunes, fortunes controlled by a single heir, or fortunes derived primarily from the state. For the purposes of this list, families whose wealth stems from a joint company or enterprise are being considered as a single entry.

From the Ferrero family whose $22.9 billion fortune comes from Nutella to the Walton family whose $151.5 billion fortune comes from Walmart, here’s a run down of the 25 richest families in the world, ranked.
