To understand public opinion about immigration in Europe, one has to understand the media's role in it. We present a literature review on research on media discourse on immigration and their effects. Despite differences in the way immigration and migrant groups are represented in European media, we can observe common patterns. Migrants are generally under-represented and shown as delinquents or criminals. Although, media framing differs based on specific migrant groups the discourse is focusing on, immigration coverage is often negative and conflict-centred. Frequent exposure to such media messages leads to negative attitudes towards migration, may activate stereotypical cognitions of migrant groups, and even influence vote choice. In addition to discussing these issues in depth, the present review also focuses on comparative findings.
