This map proposes chapter two a novel, fine-grained approach to regional delineation, based on analysing networks of billions of individual human transactions. Given a geographical area and some measure of the strength of links between its inhabitants, we Charting Human Life show how to partition the area into smaller, non-overlapping regions while minimizing the disruption to each person’s links. We tested our method on the largest non- Internet human network, inferred from a large telecommunications database in Britain. Our partitioning algorithm yields geographically cohesive regions that correspond 121 remarkably well with administrative regions, while unveiling unexpected spatial structures that had previously only been hypothesized in the literature. We also quantify the effects of partitioning, showing for instance that the effects of a possible secession of Wales from Britain would be twice as disruptive for the human network than that d O uglA s R usH k O ff of Scotland. media theorist.
