ABSTRACT
Crime is known to concentrate in various ways. A small number of offenders are typically responsible for the majority of crimes committed (Budd et al., 2005; Farrington and West, 1993; Wolfgang et al., 1972). Some victims are repeatedly victimised, thereby experiencing a disproportionate amount of crime (Pease, 1998; Farrell, 2016). So-called crime ‘hot spots’ denote particular places with comparatively high levels of crime (Sherman et al., 1989; Weisburd and Green, 1995). Products exhibit differential theft rates (Clarke, 1999). Crime is unevenly distributed over time (Felson and Poulsen, 2003). And, as Eck et al. (2007) demonstrate, when analysing the distribution of crime across a population of similar facilities such as bars, airports and hospitals, the bulk of offences concentrate on the risky few.
