Following a first series of meetings and interviews with a range of stakeholders from around the globe on metropolitan challenges and dilemmas, INTA and Deltametropolis Association decided to focus on the socio-economic development and governance of metropolitan regions in Europe.

The metropolises that were selected for this roundtable in Brussels were chosen for their relatively similar approaches to a shared European agenda, as well as similarities in size, history and culture, which allows for a comparative study. In other ways however, there are some noticeable differences between them, such as their densities, geographic position and economic profile.
