Based on an idea by French philosopher and urbanist Paul Virilio, the video installation EXIT was created by the New York–based architects Diller Scofidio + Renfro and premiered at Fondation Cartier pour l’art contemporain in Paris in 2008. Composed of a series of animated maps generated by data, this immersive installation investigated human migrations today and their leading causes, including the impact of climate change. Through six scenarios, this book, which was specially created to explain the exhibition, provides a rare opportunity to visually understand the complex relation- ships between the various economic, political, and environmental factors underpinning contemporary human migrations. For this revised volume, the data has been entirely updated, reflecting alarming changes since the piece was  first presented.
