Figure 2: Nested police data<br />

Underestimat<strong>in</strong>g offend<strong>in</strong>g<br />

The one obvious reason that police data may underestimate actual offend<strong>in</strong>g is that an offence<br />

is only recorded by the police if it comes to their attention <strong>and</strong> results <strong>in</strong> an apprehension (either<br />

as a result of a victim report or where the police are witnesses to the offence themselves).<br />

Therefore, police data generally underestimate an offender’s crim<strong>in</strong>al behaviour because<br />

undetected offences committed by that offender will never be identified. In addition, there<br />

are a variety of offences <strong>and</strong> situations <strong>in</strong> which the police do not formally record an event,<br />

even if an offence is identified by them. In the case of trivial offend<strong>in</strong>g, for example, they may<br />

choose to ignore the behaviour. Or, if they do choose to proceed, there may be other options<br />

available which do not <strong>in</strong>volve a formal apprehension. These may <strong>in</strong>clude:<br />
