LONDON (Reuters) – The top 10 people on Forbes’ list of the world’s highest-earning people rose in a significant and steady rise over the past year, with the top 10 earning more than $10 billion annually, a survey showed on Thursday.
The Forbes list of world’s 100 richest people has seen a massive increase since 2015, when the list was first created in 2016.
The index is based on an assessment of wealth by Forbes editors and includes a “firm” of people who are paid a salary or income that is based in part on their net worth.
The top 10 have more than doubled from 1,700 in 2015 to nearly 3,500 today, according to the report, released on Thursday by the Forbes 400.
That includes the 10 highest earners in the world today, including the richest woman, Chinese billionaire Guo Guangchang.
Guangchang is worth an estimated $13.5 billion, according the Forbes 200 list.
She made the list in 2016 after a long period of stasis, having been on it for more than 20 years.
The new top 10 include billionaire tech entrepreneur Peter Thiel, who owns PayPal, the online payment service that went public last year.
Thiel made $3.7 billion in 2016, and Forbes estimates he will make $20 billion this year.
The second-highest-earner is former Formula One and IndyCar racing driver and entrepreneur Ayrton Senna, whose estimated net worth is $10.2 billion.
Senna earned an estimated annual income of $2.8 billion in 2017.
The third-highest earner is Brazilian billionaire Carlos Slim, who makes an estimated net income of more than a billion dollars.
Slim is worth $3 billion.
The fourth-highest is Chinese billionaire Jack Ma, who has a net worth of more then $40 billion, making him the richest person in China.
He has been on the Forbes list for at least 15 years.
Other Forbes 400 figures include billionaire oil baron Anwar Ibrahim, who earned $3 million last year, and Indian billionaire Nandan Nilekani, who made $1.6 billion.
Nilekani is worth about $2 billion and made the Forbes 100 list in 2012.
Forbes estimates his net worth will be more than four times that.
In terms of the highest-grossing earners, the most recent Forbes 400 list of billionaires includes billionaire investor Peter Thiel with an estimated wealth of $13 billion, while Bill Gates, the co-founder of Microsoft, made $4.7 million in 2016 and $6.7 in 2017, respectively.
The report showed that China’s Xi Jinping is still the richest in the list, with a net wealth of almost $11.5 trillion.
The United States has no billionaires in the top 1 percent, the report said.
