  Title Investigating whether a crime reduction measure works Type Journal Article
  Year 2006 Publication Radical Statistics Abbreviated Journal  
  Volume 91 Issue Pages  
  Keywords Public Safety  
  Abstract Crime is a serious business. It causes great distress and fear. It costs a lot

to deal with its consequences. In these regards crime shares much with

the problem of ill-health and disease. The application of sound science and

statistics has allowed great strides to be made in dealing with problems of

ill health. Medical statistics is one of the recognised, established

disciplines involved in researching healthcare.

The parallels between research in crime reduction and in healthcare do

appear to differ in terms of quality. Although there is still room for

considerable improvement in researching health-care, an investigation

into the underpinning of statistical methods used indicates that the

problems are substantially worse in the study of crime. The consideration

given to statistics in crime studies seems rather flimsy, yet important

claims are made which are statistical at source and may affect policy, and

so can have considerable costs attached. Therefore, for example, it is

important to know whether the underlying crime level has really changed,

rather than just being the result of perhaps sampling variation or some

artefact giving rise to statistical bias or systematic error. This is necessary

when trying to determine whether a Crime Reduction Intervention (CRI)

has actually worked.

I started examining the scientific basis of the claim for the effectiveness for

one particular CRI, basically because I was concerned about negative side

effects and I thought the claim implausible. I remain concerned and

unconvinced. The statistical issues and concerns I raise apply also to

investigating other CRIs and to existing published analyses.

This piece extends work presented in Marchant (2006); earlier work on the

statistical issues involved can be found in Marchant (2005a, b; 2004).

  Title The Chicago Alley Lighting Project: Final Evaluation Report Type Journal Article
  Year 2000 Publication Illinois Criminal Justice Information Authority Abbreviated Journal  
  Volume Issue Pages  
  Keywords Public Safety  
  Abstract Begun in October of 1998, the first part of the plan sought to upgrade and improve the city's 175,000 streetlights, which illuminate the arterial and residential streets. The second part of the plan involved repairing and upgrading the lighting in and around viaducts and Chicago Transit Authority stations. The final part of the plan has been to boost lighting levels in alleys across the city as a tool for public safety and fighting crime. In the past, 90-watt lights illuminated most city alleys; alley lighting levels have been increased by installing new fixtures that can accommodate 250-watt bulbs. The Illinois Criminal Justice Information Authority undertook an evaluation to assess the impact of increased alley lighting on crime rates in two eight-square-block areas, with emphasis on crimes that were most likely to have occurred in alleys. The evaluation first examined change in the experimental area that received increased alley lighting over a 1-year period prior to increased alley lighting and a 1-year period thereafter. Next, change over a 6-month period before and after increased alley lighting was examined for both the experimental area and the control area. The evaluation found that reported offenses increased between the 1-year preinstallation and 1-year postinstallation study period in the experimental area where alley lighting was improved. The evaluation also found that the experimental area experienced more notable increases in reported incidents over a 6-month preinstallation and 6-month postinstallation study period compared to the control area. The evaluation could not provide a definitive explanation of these findings.
