In the 60,000 years since people began colonizing the continents, a continuous feature of human civilization has been mobility. History is replete with seismic global events-pandemics and plagues, wars and genocides. Each time, after a great catastrophe, our innate impulse toward physical security compels us to move. The map of humanity isn't settled-not now, not ever.

Which countries will accept or reject them? How will the billions alive today, and the billions coming, paint the next map of human geography?
