Forbes used a four-part formula to rank the world's most powerful, considering the number of people a person influences, their ability to project power, control or access to wealth and how actively a person wields their power, Daily News reports.
It was also reported, in compiling the inaugural ranking, Forbes said it had narrowed the list to 67 people, "a number based on the conceit that one can reduce the world's 6.7 billion people to the one in every 100 million that matter."
"The goal in compiling this list is to expose power and not glorify it, and over time reveal how influence is as easily lost as it is hard to gain," the magazine said.
World and industry leaders dominated the top 10 of the list, which Forbes said was assessed on the number of people the person influences, their ability to project power beyond their immediate sphere of influence, their control of financial resources and how actively that person wields power.
Also on the list were financial heavyweights including Goldman Sachs Chief Executive Lloyd Blankfein (18) and billionaire investor and philanthropist Warren Buffett (14), as well as Pope Benedict (11).
