A new set of statistics gathered by an Indian-born Harvard economist working in Barcelona, Spain, implies that visions of a globalized world are often more fancy than fact. According to Pankaj Ghemawat, less than one percent of all mail and less than two percent of all calls are international; less than three percent of the world's population are first-generation immigrants; international Internet traffic accounts for only 17 to 18 percent of all Internet traffic; 90 percent of the world's population will never leave their home country.
