Just came back from a workshop at SciencesPo where we introduced urban studies students to methods and technologies to explore and visualize urban data. During the workshop we worked on proximity and socio economic data related to the coty of Marseille to explore the idea of the proximity, diversity and inequalities. The workshop was organized by the Urban School with Xavier Timbeau, Director of the OFCE (Observatoire Français des Conjonctures Economiques) and our dear friend Donato Ricci, head of design research at the médialab, Sciences Po.
