 About three million people in the world head to cities every week. Migration is one of the catalysts for urbanization in most countries of the world. Local governments have a key role to play. They're uniquely positioned to understand how to address challenges and seize opportunities so that migration can contribute to development in their communities. In this regard, IOM, with the support of Economist Impact, has developed the Migration Governance Indicators, or MGI's. With more than 80 indicators, MGI's allow governments to take stock of the laws, policies and structures they have to manage their migration, identifying good practices and areas for improvement. MGI's process is voluntary, participatory and sensitive to specific context of each jurisdiction. After rigorous data collection, local governments and other key actors have the opportunity to discuss research results and to identify concrete actions to follow up on identified challenges. MGI's are a dynamic tool. Its results can be used to inform the development of migration or related policies as in Sao Paulo, Brazil and Medellin, Colombia, to support governments with their international commitments as in Mexico City and Santiago de Chile and to strengthen the capacities of governments, for example in Freetown, Sierra Leone and Buenos Aires, Argentina. MGI's reflect IOM's commitment to support governments in strengthening their migration governance by promoting the development of informed and coordinated policies in an inclusive manner to promote the socioeconomic well-being of migrants and their communities.
