May 26, 2017 · A weaker version, that a relatively small proportion of all places contain most crime is supported. If there is a “law” of concentration, it describes the general shape of the distribution—that a relatively small proportion places account for a relatively large proportion of crimes.

The POV project at the University of Cincinnati set out to synthesize the evidence of crime concentration for places, offenders and victims and to estimate the crime concentration for all three phenomena. In three papers published in this issue (Lee et al. 2017; Martinez et al. 2017), the authors applied a common set of methods to locate research s...
Another important comparison is between studies of crime concentration at addresses using reported crime data from the police and studies using victimization surveys of crimes at places. The second group includes crimes not reported to the police. Many victimization surveys report on place-based crime events (e.g., residential burglary and victimiz...
Based on the evidence to date, it appears that crime is about equally concentrated at places, among offenders and among victims. If there are differences, the differences are probably not great. Conservatively, one can assert that the similarity in concentration is greater than the differences. Three implications flow from these findings. First, th...

Feb 8, 2021 · The extended evidence that a small number of places accounts for the vast majority of crime events led Weisburd to propose the law of concentration of crime: that for a given microgeographic unit there is a narrow bandwidth of percentages for a defined cumulative proportion of crime events in a city. The law leaves open the possibility, however ...

Sep 1, 2024 · Using the interquartile range to exclude outliers, we found a bandwidth of 2.5 % (3.2–5.7 %) for 50 % of crime, and 1.4 % (0.8–2.2 %) for 25 % of crime. Crime concentration was generally stronger for specific types of crime, and bandwidths of concentration were generally smaller.
May 26, 2017 · We examine concentration in two conditions: when all places are studied (prevalence), and when only places with at least one crime are studied (frequency).
Jul 1, 2021 · However, a small proportion of offenders go on to commit a large proportion of crime (Prime and others, 2001; Wikström and others, 2012; Martinez and others, 2017). The Home Office (2001) estimated that 10% of active offenders are responsible for 50% of all crime committed.
