Nuno F. da Cruz, Do Young Oh and Nathalie Badaoui Choumar have authored an article in the journal Cities.
The article, titled 'The Metropolitan Scale' summarises the research undertaken in the ÐÓ°ÉÂÛ̳ Cities project Metropolitan Indicators. It employs simple definitions and heuristics to collect and present data for 58 metropolises from five continents and reflects on this experience to emphasise the obstacles that lie ahead of both scholars and policy-makers at all levels of government. The database of 38 metropolitan indicators for 58 metropolitan territories is also available .
