Background: The incidence of psychotic disorders varies between geographical areas and it is hypothesized that neighbourhood level factors such as social deprivation, fragmentation and population density may influence this variation. The aims of this study are to determine whether the incidence of FEP and the DUP are associated with the level of social deprivation, fragmentation and population density at the neighbourhood level. Methods: All individuals with a FEP from a geographical defined catchment area assessed over a five year period between 2006 and 2011 were included. Social deprivation was measured using the HP Index. Results: 292 cases of FEP were included in the study and 57% were male and 45% had a diagnosis of a schizophrenia-spectrum disorder. The standardized incidence rate of FEP ranged from 72.38 per 100,000 person years (95% C.I. 26.42 – 162.68) in the most deprived areas to 21.46 (95% C.I. = 17.56 – 26.00) in the most affluent area, indicated nearly a 3.5 fold increase in incidence in the most deprived (Rate ratio = 3.43, 95% C.I. 1.59 – 7.45, p
