Purpose of review An exploration of the evidence that a history of migration is a risk factor for schizophrenia and an evaluation of those studies that seek an explanation for this. Recent findings A meta-analysis found an increased risk for schizophrenia among first-generation and second-generation migrants and found a particularly high risk for migrants from countries where the majority of the population was Black. The latter finding was confirmed and extended by a large first-contact… 
The incidence of schizophrenia in European immigrants to Canada
Perceived discrimination and the risk of schizophrenia in ethnic minorities
The relationship between racial discrimination and psychosis may vary with the aspect of discrimination that is studied, and may also depend upon the social context in which discrimination takes place.
A meta-analysis of the risk for psychotic disorders among first- and second-generation immigrants
The increased risk of schizophrenia and related disorders among immigrants clearly persists into the second generation, suggesting that post-m migration factors play a more important role than pre-migration factors or migration per se.
Migration, ethnicity, and psychosis: toward a sociodevelopmental model.
This article proposes an integrated model--of a sociodevelopmental pathway to psychosis--to account for the reported high rates in migrant and minority ethnic populations.
Migration, Schizophrenia, and Crime: A Study From a Forensic Psychiatric Sample
Compared to the non-migrant schizophrenia patient group, the migrant patient group had less severe psychiatric symptoms and less social function impairments, which was an important factor in preventing criminality in patients with schizophrenia.
Sex-Dependent Association of Perigenual Anterior Cingulate Cortex Volume and Migration Background, an Environmental Risk Factor for Schizophrenia
The results provide convergent evidence for an impact of environmental risk factors linked to schizophrenia on gray matter volume and extend prior data by highlighting the possibility that the pACC structure may be particularly sensitive to the convergent risk factors links to schizophrenia.
Psychosis and urbanicity: a review of the recent literature from epidemiology to neurourbanism
The reviewed evidence revealed complex patterns of urbanicity–psychosis associations with considerable international variation within Europe and between low, middle and high-income countries worldwide.
First-contact incidence of psychosis in north-eastern Italy: influence of age, gender, immigration and socioeconomic deprivation
The incidence rate of first-episode psychosis in a large area of north-eastern Italy was lower than that found in other European and North American studies and provides new insights into the factors that may increase and/or decrease risk for developing psychosis.


Migration as a risk factor for schizophrenia: A Danish population-based cohort study
Migrant background and history of foreign residence confers an increased risk for schizophrenia that is not solely attributable to selection factors and may also be independent of foreign birth.
Schizophrenia and migration: a meta-analysis and review.
Findings of previous studies implicating migration as a risk factor for the development of schizophrenia and a quantitative index of the associated effect size are synthesized to suggest a role for psychosocial adversity in the etiology of schizophrenia.
First-Contact Incidence Rates of Schizophrenia in Trinidad and One-Year Follow-up
These rates are similar to those from the WHO study in Honolulu and Aarhus, and much lower than the rates for African–Caribbeans in London.
Incidence of Schizophrenia or Other Psychoses in First- and Second-Generation Immigrants: A National Cohort Study
Having one parent born in Sweden had no protective effect on the risk of being hospitalized for psychotic disorders among second-generation immigrants, and the highest risks of psychotic disorders were found among first-generation and second- Generation Finns, after adjustment for socioeconomic status.
Social adversity contributes to high morbidity in psychoses in immigrants – a national cohort study in two generations of Swedish residents
A higher risk of schizophrenia and psychoses was found in two generations of immigrants of diverse ethnicity, and the results indicate that social adversity contributes to the higher risk.
Ethnicity, Goal Striving and Schizophrenia: A Case-Control Study of Three Ethnic Groups in the United Kingdom
Poor housing conditions may be one of the risk factors contributing to the high incidence of schizophrenia in African-Caribbean patients and the gap between achievement and expectations did not appear to cause high disappointment levels in any group.

Selective migration cannot solely explain the higher incidence of schizophrenia in Surinamese immigrants to the Netherlands.
