ABOUT THIS RELEASE
The National Offence Index (NOI) is a tool which provides an ordinal ranking of the offence categories in the Australian Standard Offence Classification (ASOC) 2008 (Second Edition) (cat. no. 1234.0), according to perceived seriousness. The NOI is used in instances where there are multiple offences related to a person or criminal case, to determine a principal offence for statistical output purposes. The NOI has been revised in 2009, and is to be used in conjunction with the second edition of ASOC. This is the first time NOI has been published in its own right. This version of NOI supercedes previous versions which have been published most recently as an Appendix to the Criminal Courts, Australia 2007-08 (cat. no. 4513.0) and Prisoners in Australia, 2008 (cat. no. 4517.0) publications.
