Public perceptions of both internal and international migration are mixed, with many host communities concerned about the demands migrants place on infrastructure, public services and the job market, as well as associating migrants with common social ills. Such perceptions are often encouraged by xenophobia and other forms of discrimination. Public perceptions of migration are important as they influence migration policy as well as if migrants feel welcomed and how their integration will work out. KNOMAD will seek ways to improve communications around key findings and messages, emphasizing the many positive aspects of migration. KNOMAD also aims to understand the reasons for resistance to migration, how we have to design policies taking these into account and how we should best communicate them to the broader public.
