Assessing and responding to the impact of voluntary economic migration on development is a relatively new area of work for DFID. This paper sets out DFID’s policy, which is shaped by our mission to reduce poverty, and is consistent with the current UK policy framework on immigration, including the Home Office Immigration and Nationality Directorate Review.The aim of our work on migration is to increase the benefits and reduce the risks of migration for poor people and developing countries.The paper focuses on poor people who take a decision to leave their home and move through regular channels within their country of origin, or across international borders, in an attempt to improve their economic situation. It recognises that movement within national borders and defined regions is by far the most significant form of migration for poor people, and can help reduce poverty. DFID will therefore incorporate efforts to address migration into development policies and programmes.The paper identifies the main policy approaches that can help reduce poverty, bring about the development benefits of migration and reduce the risks. Although aimed primarily at development professionals, the paper recognises the important role of migration partners at national, regional and international level. It ends by setting out DFID’s plans for future work on migration and development.
