This paper investigates the statistical relationship between integration policies and public opinion toward immigrants. Overall, the eighteen reviewed studies indicate that integration policies are strongly associated with the general public’s level of perceived threat from immigrants and, perhaps, to their level of anti-immigrant attitudes. Inclusive policies can be said to reduce the level of perceived threat while exclusionary policies tend to reinforce perceptions of threat. Since most studies could not establish a causal link, further research is needed to corroborate the impact of integration policies on public opinion.
