The eight richest people in the world have as much money as half of the world's population, or 3.6 billion people.
That's according to a research compiled by Oxfam, an international network of organizations collectively working to alleviate global poverty.
The richest eight people in the world, Bill Gates, Amancio Ortega, Warren Buffett, Carlos Slim, Jeff Bezos, Mark Zuckerberg, Larry Ellison, and Michael Bloomberg, are worth $426 billion together. That averages out to $53.25 billion per person.
If the average rate of growth the ultra-rich have been enjoying, 11 percent per year since 2009, is applied to Bill Gates' current net worth, the 61-year-old tech titan could become the world's first trillionaire by the time he is in his mid-80s.
Meanwhile, the world's poorest 3.6 billion people have an average of less than $120 per person.
This graphic, generated by cost information website How Much with Oxfam's data, show what that wealth gap looks like.
