The newest rankings are based on a 2010 worldwide survey of 1,500 scholars, journalists, policymakers and peers from approximately 120 countries. The panel nominated and ranked nearly 7,000 think tanks from every region of the world.
“The purpose of the rankings,” said James G. McGann, assistant director of Penn’s International Relations Program, director of the Think Tanks and Civil Society Program at Penn and the one who compiled the survey, “is to highlight the important work that think tanks perform for governments and civil societies around the world, often in dangerous and difficult conditions.”
