The conference aims to assemble the collective wisdom on migration, mobility and urban transition and, together with city leaders and other experts from around the world, to draw a clear policy path towards improved migration management at all governance levels, which will benefit both migrants and cities. An important first step could be the consolidation of existing yet scattered resources, data, indexes, tools and studies. It is important to assemble this information in a global database and promote greater information-sharing and dialogue among cities, multilevel government stakeholders and other partners.
