Applying Robert Sampson’s (2012) work on interdependent spatial patterns in a new setting, we link structural characteristics of the neighbourhood to public beliefs and worries about neighbourhood violence via two intermediate mechanisms: (1) collective efficacy and (2) neighbourhood disorder. Analysing data from face-to-face interviews of 61,436 individuals living in 4,761 London neighbourhoods, we find that the strength of informal social control mechanisms and the extent of low-level breaches of common standards of behaviour communicate information about the prevalence and threat of violent crime in one’s neighbourhood. Moreover, collective efficacy partially mediates many of the statistical effects of structural characteristics of the neighbourhood on beliefs and worries about violent crime. Theoretical implications of the findings are discussed.
