• Members of the 2014 ranking represent women in 8 categories: technology, politics, business, finance, media, entertainment, philanthropy and NGOs, as well as billionaires. Finance was broken out from business as a new category this year. To determine the rank within each category, as well as overall rank on the list of 100, Forbes applied four metrics: money, media, impact and spheres of influence.
