Mapping the social structure of cities with Diffusion Maps — •Thilo Gross — Helmholtz Institute for Functional Marine Biodiversity,, Oldenburg, Germany — Carl-von-Ossietzky University, Oldenburg, Germany — Alfred-Wegener Institute, Helmholtz Center for Marine and Polar Research, Bremerhaven, Germany

Human society is aggregating and accelerating, leading to a rapid growth of cities. It is well known that the social structure of cities is important for a long list of reasons, including livability, security, sustainability, and disaster resilience. Analysis of the social structure can profit from two complementary data sources: Census datasets provide a wealth of high quality, highly structured information, but are typically only available once per decade. By contrast novel sources of mobility data (e.g. from phone traces) offer an unstructured and indirect, but rich and near-real-time glimpse of human social behavior. In this talk I illustrate how diffusion maps, a network-driven analysis method, reveal important patterns in both of these types of data.
