On the Move People are migrating at record numbers, as the gap between the haves and the have-nots grows.
Human wandering is as old as humankind, but the world has never seen so much of it.
Yet we will see even more. The flow of migrants across borders is large and accelerating, approaching four million people a year. Globally, some 125 million people today live outside their country of birth. In crassly economic terms, migration involves the poor flowing to the rich. In modern times, that means people go from the sending nations of South Asia, Africa and Latin America to the receiving nations of Europe and North America.
