The presentation will be based on a recent OECD report. It provides a new perspective on the nature of urban sprawl, its causes and its consequences. This perspective, which is based on the multi-dimensionality of the phenomenon, sets the foundations for the construction of new indicators of the concept. New datasets are then used to compute these indicators for more than 1100 urban areas in 29 OECD countries over the period 1990-2014. The report relies on cross-city, cross-country and country-level analyses of these indicators to provide insights into the current situation and evolution of urban sprawl in OECD cities. Last, the report outlines policy options to steer urban development to more sustainable forms and argues for adopting an integrated approach to this end.
