The number is down from the 388 individuals in 2010, indicating that the wealth of these 62 individuals, alone has risen by 44% over the same five-year period, marking an increase of more than half a trillion dollars to $1.76tn (£1.24tn,€1.61tn). According to the report the wealth of the bottom half of the global population fell by just over $1tn in the same period, marking a 41% decline.

Oxfam said that it calculated the wealth of the richest 62 by using data from Forbes' billionaires list published in March 2015.

The release of the report coincides with Davos 2016, the event which marks the 46th annual meeting of the World Economic Forum (WEF) that will see numerous business leaders and stalwarts from the political, civil, media and religious world including Leonardo DiCaprio and David Cameron converge at the Swiss ski resort.

The theme of this year's meet is: The Fourth Industrial Revolution. While discussions would focus on the impact of robots and artificial intelligence in the real world, the spotlight for the 2,500 participants will remain on global financial markets and whether or not the recent slowdown would provide more evidence of potential trouble in future.
