This article meta-analyses the available data on attitudes towards refugees and asylum seekers, with the aim of estimating effect sizes for the relationships between these attitudes and prejudice-relevant correlates. Seventy studies (Ntotal = 13,720) were located using systematic database searches and calls for unpublished data. In the case of demographic factors, being male, religious, nationally identified, politically conservative, and less educated were associated with negative attitudes (Fisher’s zs = 0.11, 0.17, 0.18, 0.21, and –0.16, respectively). For ideological factors, increases in right-wing authoritarianism and social-dominance orientations correlated with negative attitudes, while the endorsement of macro (but not micro) justice principles were associated with positive attitudes (Fisher’s zs = 0.50, 0.50, –0.29, and 0.00, respectively). Perceptions of refugees as symbolic and realistic threats were the strongest correlates of negative attitudes (Fisher’s zs = 0.98 and 1.11, respectively). These findings have contributed to the growing body of knowledge that endeavors to understand the antecedents of refugee-specific prejudice, and are discussed in light of the global refugee crisis.
