Research Objective

• Comparing Crime Hot Spot versus Crime Harm Spots in a

Swedish City: A descriptive research study.

May-Britt Rinaldo

Research Method and Design

• Identify all crimes in Gothenburg City

• Identify crimes against the person in public place and

cluster these crimes onto the Gothenburg City map by

location

• Create the ”Swedish Crime Harm Index”

• Assess all crimes against the person in public place with

the Swedish CHI and cluster the Swedish CHI by location

onto the Gothenburg City map

• Comparing Crime Hot Spots with Crime Harm Spots

Crime Harm Index

• The Cambridge Crime Harm Index (CHI) and the US Index for Harm-Focused Policing

uses sentencing policy (Guidelines) to assign a “weight” of severity to each offence

type. It then creates an index based on prison days.

• The Canadian Police Reported Crime Severity Index (SCI) and the Western Australian

Crime Harm Index (WACHI) uses sentences from courts for each crime type to creating

the index based on prison days.

• The Swedish Crime Harm Index is based on estimated sentence for each crime

that the offender can spend in prison. (Guiding verdicts from the Court of Appeal

and precedents the Supreme Court)

• The Danish Crime Harm Index is based on the Director of Public Prosecutions (DPP)

specifying what sentence the prosecutor should ask for in court when having a first time

offender charged without mitigation or aggravating factors.

• These Indexes can be calculated within societies or cities over time, across areas within

cities, and across offenders and victims in their individual crime histories.

Summary of Findings

• 2,630 crimes against the person in public place

• Swedish Crime Harm Index: 333,871 prison days

• 60 locations make up for nearly half the crime harm (154649 days =

46,3 %) (= top 5% of CHI Harm per location)

• Number of crimes in these top 5% locations ranges from 1 – 45.

• The top 60 CHI spots include the 4 locations that are also hot spots:

– The highest hotspot is also the highest harm spot,

– Two hotspots within the top 1% of CHI spots, 1 hot spot is in the top 2% of CHI

spots.

• A sole focus on Hot Spots would miss 50% of CHI spots

• A sole focus on CHI would miss 53% of hot spots
