Applying tests for clustering and dispersion against robbery, residential burglary and vehicle crime data from the London Borough of Croydon. The table below shows the results of clustering and dispersion tests applied to three crime types in the London Borough of Croydon. The crime data is for the period June 1999 – May 2000.
All three crime types show evidence of clustering, therefore hotspots of crime exist for each. The standard distance dispersion measure is a relative measure. Robbery has the lowest standard distance measure so it is described to be the least dispersed of the three crime types. Vehicle crime is the most dispersed. These tests reveal that hotspots are expected when each of the crime types are mapped. Vehicle crime is the more dispersed of the three suggesting that whilst hotspots do exist, these hotspots may be more dispersed than that of the other two crime types, or that crime is less concentrated into a single or fewer number of hotspots than residential burglary or robbery. |
