A Meta-Analysis of Attitudes Towards Migrants and Displaced Persons

Since the 2010s, social scientists have increasingly conducted survey-experimental studies that explore what factors drive public attitudes towards migrants in host countries. We conducted a systematic meta-analysis of 118 such studies, comprising 428,881 respondents from fifty-three countries. We find that sociotropic economic concerns play a key role, with individuals being more welcoming towards migrants who contribute to the economy through their professional occupation, education, or language skills. In contrast, there is limited evidence that hosts evaluate migrants based on egocentric economic concerns. Cultural concerns are also important; notably, we uncover a persistent anti-Muslim bias. Humanitarian concerns shape attitudes as well – especially towards forcibly displaced migrants, who are generally viewed more favorably than economic migrants. Climate migrants place between conflict migrants and economic migrants in terms of public perception. Our meta-analysis raises several questions that remain unanswered in the literature, suggesting important directions for future research.
