The World's Most Powerful Women
Elizabeth MacDonald and Chana R. Schoenberger 08.31.06, 6:00 PM ET
Our annual listing of the 100 most powerful women in the world is based on a power ranking that is the composite of visibility (measured by press citations) and economic impact. The later, in turn, reflects three things: résumé (a prime minister is more powerful than a senator); the size of the economic sphere over which a leader holds sway; and a multiplier that aims to make different financial yardsticks comparable. For example, a politician is assigned a gross domestic product number but gets a low multiplier, while a foundation executive is assigned the foundation’s assets but gets a high multiplier.
