Migration is a global phenomenon that concerns all countries and through which it is possible to reduce the poverty of migrants themselves in their countries of origin and host countries, as well as to contribute to the achievement of the SGDs in their original and host communities. If we focus on migration and host countries, this involves the different levels of the State but above all, by proximity, it concerns in a very special way the local level, close to the day-to-day life of the citizens in the guarantee of their rights and regarding the quality of life of migrants, particularly vulnerable for asylum and refugee seekers. That is why, local governments, as Madrid City Council, have a concrete responsibility to provide social protection and foster the integration of all migrants and refugees in their host societies. The case study of the city of Madrid shows us that SSE has a crucial role in combating some of the significant difficulties facing refugee and migrant populations, such as overcoming social exclusion and xenophobia, and accessing decent work. However, despite migration can be a powerful poverty reduction tool, which can contribute to the achievement of the SGDs, SSE in Madrid has not served over the past four years as a catalyst for this.
