This chapter explores a range of factors shaping attitudes towards immigrants in 18 countries in West and North Africa based on results from the Gallup World Poll survey. In particular, it looks at the relationship between public opinion on immigration and (a) individuals’ perceptions of their countries’ economy and labour market, (b) their perceptions of the quality and availability of public goods and services, and (c) their trust in institutions such as the police and government. These have all been identified as important factors affecting public opinion on immigration in the literature.
