In Bloomberg's Billionaires Index, updated daily at the close of the markets in NYC, women make up just 12 of the 100 spots available. Just one Australian, Gina Rinehart, makes the list.
Check out how these cashed-up women generated their wealth, from the least wealthy (on a measly $11.2 billion) to the most ($33.5 billion). All figures are in US dollars.
12. Abigail Johnson, United States, $11.2B
Abigail Johnson owns 24.5% of Fidelity Management and Research LLC, which owns the second-largest American mutual fund company Fidelity Investments, of which she is president. She is also vice chairman of FMR LLC. Fidelity Financial Services was created by her grandfather in 1946, with the company now overseeing around $1.6 trillion.

11. Johanna Quandt, Germany, $11.7B

Her daughter Susanne Klatten also appears in this list.
10. Sara Mota de Larrea, Mexico, $12.4B
Sara Mota de Larrea inherited a 36% stake in Grupo Mexico when her husband Jorge Larrea died. Larrea's road to wealth started with a construction company before he moved into mining, which included buying privatised government assets. The Grupo Mexico includes the world's seventh-largest copper producer, Mexico's largest railroad company and an oil drilling business. Between Sara and her son German, they own 51% of the company. The mining company was rocked by a four-year strike at one of their mines until 2010. The fairly private Larrea family has been involved in a range of lawsuits in the last few years.
9. Dirce Camargo, Brazil, $14.0B
Dirce Camargo has run Camargo Correa, one of Brazil's most significant companies, since her husband Sebastiao Camarago died in 1994. The industrial conglomerate, a range of publicly and privately owned companies, has businesses in cement, energy, construction, roadways, real estate, ship building, airports, and oil and gas. While Carmgo owns the largest part of the company, the company is run by professional administrators. Two of Dirce and Sebastaio's three daughters are married to Camargo company directors. She is the third wealthiest Brazilian. Camargo, like Larrea, is reported to be a very private person.
8. Susanne Klatten $14.3B
Klatten, like Johanna Quandt, inherited her stock options after the death of her father Herbert Quant, taking a 50.1% of chemical firm Altana and 12.6% stake in BMW.

She earned a bachelor's degree in business administration from the University of Buckingham and her MBA at IMD Business School in Switzerland.

After she inherited the company in 1957, Bettencourt did not take on the president role but remained engaged as a major stakeholder.
