Who is the richest of them all? Private wealth consultancy Wealth-X has calculated the wealthiest women by region. And No. 1 is American.
The oldest on the list is 92 and the youngest is just 33, according to Wealth-X. But these women are still far outnumbered by the number of male billionaires. There were 2,039 male billionaires in 2014, accounting for 87.7 percent of the world’s total billionaire wealth of $7.3 trillion, but only 286 female billionaires in 2014, accounting for a 12.3 percent share of global billionaire wealth. Still, the global population of billionaires rose 7 percent to 2,325 this year over last.
Only one woman on the list is self-made. And women are under-represented elsewhere when it comes to wealth and power, as well. Just over 5 percent of CEO positions in Fortune 1,000 companies are held by women. Women currently hold 99 of the 535 seats in Congress: 20 of the 100 seats in the Senate, and 79 of the 435 seats in the House of Representatives, according to the Center for American Women and Politics at Rutgers University. And 60 of the 172 active judges currently sitting on the 13 U.S. federal courts of appeal are women, according to the National Women’s Law Center.
