The U.S. and China are now home to a similar number of billionaires, according to Forbes' latest billionaires list. Russia is also a strong presence in a list that encompasses $6.4 trillion in global wealth.

Many billionaires have held the title of richest in their country for a number of years, but as always, there are a number of new titleholders this year.
