Migration has historically served as a historical lever upon which countries construct their development strategies and monetary and financial policies. This research traces the development impact of remittances and social capital taken back by migrants to their home communities in urban areas. The research is built on the assumption that migration has a developmental and urban dynamic that sees migrants work as development agents in their local communities. For this reason, the sectors and areas that absorb the migrants’ financial returns the most have been sketched by dismantling the sociological background their action. This action has been associated with diverse social criteria and contexts, which has had a clear impact on the developmental effectiveness of their investment behaviour.
