The number of women billionaires in the world is rising fast, with a growing number of them from Asia and self-made, Swiss bank UBS Group AG said in a study released on Tuesday.
There are nearly seven times more women billionaires than 20 years ago and their average wealth has nearly doubled to $4.3 billion - topping the average $4 billion net worth of male billionaires, the bank said.
UBS, which offers wealth-management services, tallied 1,347 billionaires from around the world in the study but declined to name any of them.
Men still accounted for the overwhelming . . .
