ABSTRACT
Dual citizenship has recently been at the center of vigorous public debate around the world. The question of whether the citizens of one nation should be free to become citizens of another nation without first renouncing their allegiance to the first is a question that is being thrashed out in every corner of the globe from Europe to the Americas to Africa, Asia and Oceania. 1 Despite the breadth of the debate, there is very little information about the number dual citizens in the world. And without the numbers, it is difficult to know how important the debates really are.
