About Metropolis

Metropolis, World Association of the Major Metropolises, is the global network of major cities and metropolitan areas. It brings together the governments of 139 urban agglomerations worldwide. With 33 years of history, today the association is the focal point of expertise on metropolitan governance. Raising the voices of metropolises to the global agenda and building capacity to deliver public policies and services, Metropolis contributes to finding common answers to the challenges of metropolisation. Metropolis operates, as well, as the metropolitan section of the World Organisation of United Cities and Local Governments (UCLG), since its constitution, in 2004.
