Abstract Many studies have identified urban-rural differences in schizophrenia risk. The underlying cause(s) may hypothetically include toxic exposures, diet, infections, and selective migration. In a recent study, we concluded that some of the cause(s) responsible for the urban-rural differences in schizophrenia risk are rooted in families, but some might also be rooted in individuals. First, we describe temporality as a potential methodological pitfall within this line of research, then we… 
Urban birth and risk of schizophrenia: a worrying example of epidemiology where the data are stronger than the hypotheses
TLDR
The psychiatric research community should have a sense of urgency in exploring the mechanisms linking urban birth and risk of schizophrenia, and the attributable fraction of schizophrenia associated with urban birth may increase.
The role of genetic liability in the association of urbanicity at birth and during upbringing with schizophrenia in Denmark
TLDR
While results regarding urbanicity during upbringing were somewhat equivocal, genetic liability as measured here does not appear to explain the association between urbanicity at birth and schizophrenia.
Exploring the causal nature of neighborhood influences on violent criminality, substance misuse and psychiatric morbidity
Individuals who live in socioeconomically deprived neighborhoods, particularly in urban settings, experience elevated risk of being convicted of violent criminality, to engage in substance misuse and
Does population density and neighborhood deprivation predict schizophrenia? A nationwide Swedish family-based study of 2.4 million individuals.
TLDR
Excess risks of psychiatric morbidity, particularly schizophrenia, in densely populated and socioeconomically deprived Swedish neighborhoods appear to result primarily from unobserved familial selection factors.
Urbanicity of place of birth and symptoms of psychosis, depression and anxiety in Uganda
TLDR
Urban birth (but not semi-urban) was associated with more lifetime psychotic experiences, especially grandiosity, and more symptoms of psychosis, depression and anxiety during the past week, albeit the nature of the mechanism remains elusive.
No Evidence of Association between Childhood Urban Environment and Cortical Thinning in Psychotic Disorder
TLDR
The negative association between (familial risk for) psychotic disorder and CT was not moderated by developmental urbanicity, suggesting that reduced CT is not the outcome of familial sensitivity to the proxy environmental factor ‘urban upbringing’.
Environmental Risk Factors for Schizophrenia
TLDR
This chapter summarizes the evidence for various prenatal exposures, including candidates related to infection, nutrition, and pregnancy and birth complications, and outlines general directions for future research.
Urbanicity and schizophrenia. From statistical association to causality?
TLDR
The incidence of schizophrenia for a long time has been considered to be distributed more uniformly in various regions and settings, but new insight has been provided recently by studies comparing incidence rates of schizophrenia in urban and rural areas.

Are the cause(s) responsible for urban-rural differences in schizophrenia risk rooted in families or in individuals?
TLDR
In this analysis, the nearest older sibling's place of birth had an independent effect; among persons who lived in a rural area during their first 15 years of life, the relative risk was 1.59 (95% confidence interval: 1.10, 2.30) if their nearest older siblings had been born in the capital area as compared with a rural areas.
Urbanization and traffic related exposures as risk factors for Schizophrenia
TLDR
The cause(s) or exposure) responsible for the urban-rural differences in schizophrenia risk were closer related to the degree of urbanization than to the geographical distance to nearest major road.
Family history, place and season of birth as risk factors for schizophrenia in Denmark: A replication and reanalysis
TLDR
The risk of schizophrenia was increased by urbanicity of place of birth and by family history of schizophrenia or other mental disorders, and urban–rural differences of schizophrenia risk were replicated and could not be associated with the potential sources of bias the authors assessed.
Confirmation of synergy between urbanicity and familial liability in the causation of psychosis.
TLDR
It is suggested that a substantial proportion of the population morbidity force of schizophrenia may be the result of gene-environment interactions associated with urbanicity.

TLDR
Rather than ‘urbanicity’ being an independent aetiological factor in schizophrenia, its effect may be largely explained in terms of migration and social class.
Regional variation in the incidence of schizophrenia in Finland: a study of birth cohorts born from 1950 to 1969
TLDR
Urban birth is a risk factor for schizophrenia in Finland in cohorts born since 1955, and genuine spatial clustering of schizophrenia in eastern Finland was also observed, possibly caused by genetic isolation.

TLDR
There was no evidence of time trends in the urban–rural differences in the incidence of schizophrenia in Denmark, suggesting that the cause(s) responsible for these differences were not related to exposures that became more prevalent in urban areas over time.

Evidence of a dose-response relationship between urbanicity during upbringing and schizophrenia risk.
TLDR
Continuous, or repeated, exposures during upbringing that occur more frequently in urbanized areas may be responsible for the association between urbanization and schizophrenia risk.
Urbanization and psychosis: a study of 1942-1978 birth cohorts in The Netherlands.
TLDR
High rates of psychosis in urban areas may be the result of environmental factors associated with urbanization, the effect of which appears to be increasing over successive generations.
