ABOUT THIS PUBLICATION

The National Offence Index (NOI) has been developed by the Australian Bureau of Statistics as a statistical tool to enable the output of nationally comparable offence information within the field of crime and justice statistics. The Index detailed in this publication supersedes the second version of the NOI released in 2009.

The National Offence Index is a tool which provides an ordinal ranking of the offence categories in the Australian and New Zealand Standard Offence Classification (ANZSOC) (cat. no. 1234.0) according to perceived seriousness in order to determine a principal offence. The purpose of the NOI is to enable the representation of an offender by a single offence in instances where multiple offences occur within the same incident or where defendants have multiple charges in criminal cases. For instance, where an offender has two or more offences within the same incident that could be classified to different offence categories of the ANZSOC classification (e.g. 0211 - Serious assault resulting in injury and 0621 - Blackmail and extortion), by applying the NOI, a 'principal offence' can be selected to represent that offender. In this instance 'Serious assault resulting in injury' is ranked higher on the NOI (25 vs 45), and as such would be selected as the principal offence.

The NOI has been revised to assign rankings to offence categories that were previously unranked. This change will bring greater clarity and comparability around the determination of a principal offence.
