One problem with polling attitudes on identity is that "global citizenship" is a difficult concept to define and the poll left it open to those taking part to interpret.
For some, it might be about the projection of economic clout across the world. To others, it might mean an altruistic impulse to tackle the world's problems in a spirit of togetherness - whether that is climate change or inequality in the developing world.
Global citizenship might also be about ease of communication in an interconnected age and being able to have a voice on social media.
And for many, it will be about migration and mobility. We are, after all, witnessing the biggest movements of people since the World War Two.
This is not just driven by war and conflict. It is also because the world as a whole is becoming more prosperous and air travel is becoming more affordable to the rising middle classes.
