"The world's 200 wealthiest people made a combined $237 billion (£193.3 billion) this year, according to the Bloomberg Billionaires Index, bringing their total net worth up to $4.4 trillion (£3.4 trillion)." "Meanwhile, the world's poorest 3.6 billion people — just under half the world's population — had a net worth of $1.76 trillion (£1.44 trillion) in 2015, according to a study by Oxfam, amounting to just $488 (£398) per person."
