ABOUT THIS PUBLICATION
This publication presents statistics relating to offenders who were proceeded against by police during the period 1 July 2010 to 30 June 2011, for all states and territories. These statistics describe the characteristics of offenders, including the principal offence for which offenders were proceeded against. Data are also presented on the number of police-initiated court and non-court actions against offenders.
CHANGES IN THIS ISSUE
In the 2010-11 issue, there has been a change to the structure of the Recorded Crime - Offenders publication from previous issues. Chapter 1 presents an introduction to the Recorded Crime - Offenders collection and how it fits within the criminal justice system. Chapter 2 presents a national view of offenders proceeded against by police during the period of 1 July 2010 to 30 June 2011. Chapter 3 presents selected data about offenders for each of the respective states and territories. Chapter 4 presents selected data relating to police proceedings, providing a count of all separate occasions where an offender has legal action initiated against them, for all states and territories except Western Australia during the period of 1 July 2010 to 30 June 2011.
For the Recorded Crime - Offenders 2010-11 publication, principal offence data are presented by selected Australian and New Zealand Standard Offence Classification (ANZSOC) subdivisions for the first time. These data are available at the national level, as well as at the state and territory level and are available for the 2008-09, 2009-10 and 2010-11 collection periods. As a result, two new tables have been introduced in Chapter 2 and Chapter 3 (Tables 2.2 and 3.2).
For the first time, age standardisation has been applied to Indigenous status data. Age standardisation is a statistical method that adjusts crude rates to account for age differences between study populations. Within the Recorded Crime - Offenders collection, age differences are observed between offenders who self-identified as Aboriginal and Torres Strait Islander and offenders who identify as non-Indigenous. This has resulted in one additional table in Chapter 3 (Table 3.9) in which age standardisation is applied to Indigenous status data from selected states and territories. For further information refer to paragraphs 32-37 of the Explanatory Notes.
INTERPRETATION OF RESULTS
The statistics contained in this publication are derived from administrative systems maintained by state and territory police. Data have been compiled according to national standards in order to maximise consistency between the states and territories. The Explanatory Notes, Appendices and Glossary provide detailed information on the data sources, counting rules and terminology, classifications and other technical aspects associated with this collection.
Discrepancies may occur between sums of component items and totals across tables due to rounding and randomisation.
