Where will you live in 2030? Where will your children settle in 2040? What will the map of humanity look like in 2050?

In the 60,000 years since people began colonising the continents, a recurring feature of human civilisation has been mobility - the ever-constant search for resources and stability. Seismic global events - wars and genocides, pandemics and plagues - have only accelerated the process. The map of humanity isn't settled, not now, not ever.

As climate change tips toward full-blown crisis, economies collapse, governments destabilise and technology disrupts, we're entering a new age of mass migrations - one that will scatter not just the dispossessed but all of us. Which areas will people abandon and where will they resettle? Which countries will accept or reject them? As today's world population, which includes four billion restless youth, votes with their feet, what map of human geography will emerge?

Here global strategy advisor Parag Khanna provides an illuminating and authoritative vision of the next phase of human civilization - one that is both mobile and sustainable. As the book explores, in the years ahead we'll move people to where the resources are and technologies to the people who need them, returning to our nomadic roots while building more secure habitats. Move is a fascinating look at the deep trends that are shaping the most likely scenarios for the future. Most importantly, it guides each of us as we determine our optimal location on humanity's ever-changing map.
