Hardly anyone is a migrant – only 3% of us
In 2013, according to the World Bank, there were 232 million people living outside the country of their birth. This is a significant number: but it isn’t overwhelming. It means that just 3% of the world’s 7 billion inhabitants are international migrants. The real puzzle about the age of global mobility is arguably not why so many people are moving across borders, but why so many are not.
