3 The scope of this collection includes victims of attempted and completed offences classified to divisions and/or subdivisions of ASOC. Selected offences include:
4 National data for assault and sexual assault are not available for recorded crime victims, however national data for these offences are available from the 2005 National Crime and Safety Survey and the 2005 National Personal Safety Survey. For further information see paragraphs 136-138.
5 The scope excludes the following:
6 A victim can be a person, a premises, an organisation or a motor vehicle depending on the type of offence.
7 With the exception of motor vehicle theft, statistics relate to both completed and attempted offences, i.e. those where the intent is not fulfilled. Attempted motor vehicle thefts are excluded from the scope of the collection due to difficulties in distinguishing these offences from criminal damage.
8 Attempts to commit an offence are classified to the same ASOC subdivision/group as completed offences. The exception to this is murder, where murder and attempted murder are distinguished as separate offence categories.
9 Offences may include those which at a later point in time are determined to be unfounded, i.e. false or baseless.
10 Some victims of minor offences may not be recorded on crime recording systems by police in all states and territories.
11 Statistics in this publication are derived from information on victimisation incidents collected by the ABS in aggregate form from administrative records held by police agencies within each state and territory.
12 National statistics require a level of uniformity when compiling data from different states and territories. A number of standards, classifications and counting rules have been developed since the inception of this collection to improve national comparability. However, over time significant changes in the business rules, procedures, systems, policies and recording practices of police agencies across Australia have resulted in some discrepancies in data between states and territories for some offence types.
13 Findings from the Differences in Recorded Crime Statistics (DiRCS) project released in 2005 indicated that data for assault and sexual assault were not comparable across all states and territories. Testing of these offence types highlighted that there were inconsistent recording practices across the states and territories. Some jurisdictions almost always record a reported criminal incident on their crime recording system, whereas other jurisdictions apply a threshold test prior to a record being made (e.g. whether the victim wishes to proceed against the offender, or the seriousness of the incident). These thresholds varied across jurisdictions and were not guided by national standards.
14 The project also concluded that once a crime had been recorded in a crime recording system there was no evidence to suggest that processes within any state or territory had a significant impact on differences in recorded crime statistics.
15 In considering other aspects of recorded crime statistics, the DiRCS project concluded that information for offence types other than assault and sexual assault were satisfactory for the level of comparison presented in this publication. Where there are known specific issues for individual states and territories, these are described in paragraphs 33-109.
16 As a consequence of the lack of data comparability for assault and sexual assault, national data for these offence types are not available and the data provided in this publication for individual states and territories should not be used for cross-jurisdiction comparisons. Indexes are provided to assist in interpreting change over time within each jurisdiction. These indexes show movements in victimisation rates over time by comparing each offence group for each year with that offence group in a base year. For further information on indexes see paragraphs 129-132. Further classification developments will improve these offences in the future see paragraphs 18-25.
17 A paper outlining the conduct and outcomes of the DiRCS project is available on the National Statistical Service website <http://www.nss.gov.au>. The paper was prepared by the ABS National Crime Statistics Unit (NCSU) on behalf of the NCSU Board of Management.
NATIONAL CRIME RECORDING STANDARD
18 The following describes changes that have occurred or are underway in the recording of crime victimisation statistics by police agencies which may influence crime victimisation counts.
19 A National Crime Recording Standard (NCRS) was developed to address the lack of a uniform standard in the initial police recording processes. This standard will complement the already established classifications and counting rules for the Recorded Crime - Victims statistics collection and improve the level of comparability of these statistics across jurisdictions.
20 The NCRS, comprising a uniform set of business rules and requirements has been developed in collaboration with police agencies across Australia to guide the recording and counting of criminal incidents for statistical purposes and enable consistency in recording. A comprehensive set of scenarios has also been developed which underpin the rules and requirements of the NCRS and provides police agencies with guidance about how to deal with an incident from the point at which it comes to police attention to the point at which it is recorded into crime statistics. The main objective of the NCRS is to provide clear guidance to police agencies on the criteria to be considered when making a judgement as to what should be recorded on police recording systems to meet national crime statistical requirements.
21 The application of the rules and requirements of the NCRS enable the recording of crime for statistical purposes in a comparable manner, while still allowing for the recording and retaining of information on police systems for the primary reasons of operational investigation and law enforcement. Given the nature of policing, many factors ultimately influence the level of recorded crime. Social, cultural and economic factors may influence the level of criminal offending or the level of reporting to police. Recorded crime statistics are the by-product of an administrative system and will be affected by changes within that system. The introduction of new technologies or changes in police business practices and resources are also likely to influence levels of recorded crime which may not necessarily reflect changes in the actual number of criminal incidents. Changes to legislation may also have an impact on the level of recorded crime and on the types of offences recorded.
Implementation of the NCRS
22 Given that law enforcement is administered separately by each of the state and territory police agencies in Australia, the date of implementing the NCRS varied across Australia and was based on operational capacity to implement. All jurisdictions have implemented the standard, however the date of implementation varied:
Victoria - June 2008
Queensland - June 2007
South Australia - September 2007
Western Australia - January 2007
Tasmania - June 2008
Northern Territory - May 2007
Australian Capital Territory - January 2008.
23 Three jurisdictions (New South Wales, Victoria and Tasmania) partially implemented the standard during 2008. Minor changes to the recording of outcomes are yet to be implemented by most jurisdictions.
The impact of the NCRS on Recorded Crime Victim Statistics
24 One of the challenges of introducing the NCRS is establishing whether its implementation will artificially inflate or deflate any or all of the offences within the Recorded Crime - Victims statistics collection. As police crime statistics are a by-product of the administrative processes of law enforcement it is not feasible to quantify the impact of the NCRS on crime recording. However, extensive consultation with police agencies has been undertaken and the data suggests that most jurisdictions are not experiencing significant differences as a result of implementing the NCRS. The introduction of new state and territory based legislation and more pro-active policing policies in relation to family and domestic violence over recent years has potentially seen a greater alignment in the recording of assault related offences across the jurisdictions. The historical time series for all offences, except assault and sexual assault, have not been significantly impacted.
25 National offence data for assault and sexual assault offence types will be available once all jurisdictions have implemented the NCRS and are able to supply a full calendar year's worth of data. The earliest this is anticipated is for the 2009 reference year, expected to be released in 2010.
26 This publication presents data for Indigenous victims for a selected range of personal offences for New South Wales, South Australia and the Northern Territory. Limited data are available for Queensland on the ABS website. Based on an ABS assessment of the quality, Indigenous data for recorded victims of crime for other jurisdictions are not of sufficient quality for national reporting in 2008. Further work is under way with other jurisdictions to improve the quality of the Indigenous data for crime statistics.
27 Data should not be compared to previously published experimental data. It is possible that the Torres Strait Islander component of Indigenous status data is slightly inflated, due to persons incorrectly identifying as such, when they are of other islander origin, such as Pacific Islander. This is thought to have little significant effect upon the final data. For information about Indigenous rates refer to paragraphs 125-128 of the Explanatory Notes.
ABS Standard Indigenous Question
28 The ABS Standard Indigenous Question is based on self-identification by the individual who comes into contact with police, and should be asked at a minimum of all victims of crimes against the person. The answers to the Standard Indigenous Question can be ‘No’, ‘Yes, Aboriginal’, or ‘Yes, Torres Strait Islander’. If the victim is of Aboriginal and Torres Strait Islander origin, both responses should be recorded. If a victim does not supply an answer to this question, or is not asked, the Indigenous Status field is recorded as 'not stated'. Where individuals are not able to provide an answer for themselves, jurisdictions may accept a response where a next of kin/guardian provides the information.
RELATIONSHIP OF OFFENDER TO VICTIM
29 Data about the relationship of an offender to a victim have been re-introduced in 2008 following improvements to the quality of this data. Selected offences are presented where they meet the current quality threshold. These data were last published in 2004. Historical data should not be compared with 2008 data due to the earlier quality concerns.
30 The relationship of offender to victim is defined as the relationship of the alleged offender to the victim as perceived by the victim at the time of the offence, not when an offender is apprehended at a later date.
31 Data are not available for Western Australia in 2008 as it is not captured on the same basis as other states and territories (i.e. at the time the offence is recorded). New South Wales is unable to provide data for robbery offences. Several jurisdictions are unable to provide data for other theft and blackmail/extortion as the victim can be either a person or an organisation, therefore these offences have been excluded from tables. Victoria record the relationship of the victim to offender rather than the offender to the victim. Data are recoded to meet the Recorded Crime - Victims relationship classification.
32 There is some inconsistency in coding of current and former boyfriends and girlfriends across the jurisdictions, which should be taken into account when making comparisons.
STATE/TERRITORY SIGNIFICANT EVENTS AND SPECIFIC ISSUES
33 The following information highlights events or processes unique to a jurisdiction that may have had an impact on the data for this collection. This may include specific initiatives, recording practices, changes to legislation or policy to combat particular types of crime. This information has been supplied by each police agency.
New South Wales
34 Improvements to quality assurance processes during 2006 and during 2008 have resulted in a reduction of weapons 'not further defined' and a reclassification of these data to other weapon use categories. Care should be taken when comparing data prior to 2006 and data for 2007 for weapon use categories as the data are not strictly comparable.
35 During 2007 weapon use data for kidnapping/abduction offences were imputed with the exception of the total for this offence type.
36 New South Wales robbery counts are no longer comparable prior to 2005 as these are understated. Additional robbery victims were identified through a change in counting methodology. Given the significance of the contribution of New South Wales to the Australian estimate, national data are also not comparable prior to 2005.
37 Unlawful entry with intent counts are no longer comparable prior to 2006 as data were previously overstated. Given the significance of the contribution of New South Wales to the Australian estimate, national data are also not comparable prior to 2006. Improved quality assurance procedures have ensured that the data reflects the counting rules as described in paragraph 118.
38 Care should be taken when comparing other theft location data from 2006 to prior years as quality assurance improvements have been made to this offence type. For the offence other theft, a number of 'not further defined' categories that previously appeared in total residential are now accurately being recorded under outbuilding/residential land. Transport locations prior to 2006 were also previously overstated; other theft from car parks are now categorised to the appropriate location category.
39 Counts of kidnapping/abduction may be inflated slightly. 'Deprivation of liberty' (which is out of scope for this collection) is not separately identifiable on the COPS system; therefore counts of this offence type are also included in the kidnapping/abduction offence category.
40 Leaving restaurants without paying and failing to pay for petrol form part of the offence category of other theft for this collection. New South Wales, however, has excluded these offence types from this category, as they are categorised as fraud, which is out of scope of this collection.
41 All family and domestic violence related assaults are recoded even if the victim does not want to proceed.
42 An assault will still be recorded if there are no signs of injury and the victim does not wish to take the matter further. There is a propensity in New South Wales to record assault as a part of public disturbances (e.g. a pub brawl).
43 Sexual assault counts include incidents committed prior to the reference period but reported to police in that reference period.
44 If after a report of a sexual assault further investigation reveals no grounds to suggest a crime took place, a record of the original incident will remain and will be included in counts.
45 A motor vehicle theft is recorded even if it is later determined that the motor vehicle had not been stolen.
46 In July 2008, the Infringement and Other Acts Amendment Act 2008 provided for a two year trial of additional offences which are able to be dealt with by the issue of an infringement notice for persons aged 18 years and over. During the trial, police will have the ability to issue new official warning notices for most offences. This initiative may have contributed partly to the increase in other theft.
47 Sexual assault data have been revised from 1993 to 2007 to include all offences in scope for this collection of the offence of sexual assault. The large increase from 2005 to 2006 was partly attributed to renewed efforts to improve business practices in relation to police responding to reports of sexual assault. This includes the release in 2005 of The Code of Practice for the Investigation of Sexual Assault, aimed at ensuring a co-ordinated and efficient response from all services, including police, sexual assault counsellors and forensic medical officers.
48 Sexual assault counts may include incidents committed prior to the reference period but reported to police in that reference period.
49 Victoria may record an offence (where the facts indicate that a crime has been committed) if the victim does not wish to proceed, depending on the severity of that offence.
50 The Family Violence Code of Practice for the Investigation of Family Violence was introduced in August 2004, and has influenced an increase in assault counts since that time. This initiative involved a proactive approach by police and prosecutions in gathering evidence, investigation and laying charges, where appropriate, relating to family violence. It has also led to more victims feeling confident in reporting family violence to police.
51 Property taken in association with UEWI may not always be identified due to limitations in recording options in the Victoria Police LEAP computer system. Therefore caution should be used when assessing the subcomponents of UEWI. The total counts for UEWI are correct, however further disaggregation results in an undercount for 'UEWI - involving the taking of property' and an over count of 'UEWI - other'.
52 In July 2004, there was a change to the procedures for recording theft of bicycle offences. Bicycles stolen during the commission of another offence such as burglary were no longer counted separately and therefore the bicycles from 2004 onwards are recorded as property items attached to the burglary. This change brings Victoria's recording practices in line with national standards. This change may have contributed to the reduction in other theft offences from 2004 to 2005.
53 The following initiatives were in operation in Victoria:
54 Victim counts for property offences prior to 2007 are no longer comparable and should not be compared. A new IT system, QPRIME was introduced in June 2007 resulting in changes to the way in which victim counts were recorded. Data from 2007 are likely to be undercounted for property offences, however, this cannot be quantified. Related offence information such as weapons, location and Indigenous status have also been impacted.
55 The NCRS was also introduced in June 2007. The impact of the NCRS cannot be established as it coincided with the release of the new IT system, however, this change was not expected to have had a significant impact.
56 Caution should be exercised when comparing 2007 transport and other community location data prior to this period and post 2007. During 2007 some data about the location of the incidents were incorrectly coded to 'transport' instead of 'other community' location, therefore 'transport' data were overstated, while 'other community' data were understated.
57 Queensland's Domestic and Family Violence Protection Act 1989 was amended by the Domestic and Family Violence Protection Regulation, which commenced on 10 March 2003. The relevant chapter of Queensland Police policies and procedures requires police to take action where an investigating officer determines that there is sufficient evidence to do so. Charges may be pursued under the Criminal Code or other Acts in addition to proceedings under the Domestic and Family Violence Protection Act. In addition, an investigation is to be made where a police officer has a 'reasonable suspicion' that domestic violence is occurring or has occurred.
58 Sexual assault counts may include incidents committed prior to the reference period but reported to police in that reference period.
59 The increase in kidnapping/abduction offences for 2004 was possibly a result of increased public awareness of these types of offences. The media and the police had established a working partnership to encourage immediate reporting of kidnapping/abduction offences and thereby increase the chances of apprehending the offenders responsible.
60 Leaving a restaurant without paying forms part of the offence category of other theft for this collection. Queensland, however, has excluded this offence type from this category, but may include it in categories out of scope of this collection.
61 Data for offences that are deemed after investigation to be 'unsubstantiated' and/or 'unfounded' are excluded.
62 The Statutes Amendment and Repeal (Aggravated Offences) Act 2005 came into effect 15 May 2006. This has widened the scope for offences such as assault, kidnapping/abduction and blackmail/extortion in South Australia. Offences that are of a threatening nature, such as threat to endanger life or threat to injure, are included in scope of these offence types due to this legislative change. For the RCVS collection, threats of assault that are not face to face are not in scope and are excluded from the assault offence; only face to face threats are included. South Australia cannot exclude non-face to face threats of assault. Offence of a threatening nature however are implicit in offences such as robbery, kidnapping/abduction and blackmail/extortion and should be included in the RCVS collection. Part of the increase in assault, blackmail/extortion and kidnapping/abduction in 2007 are due to the implementation of this legislation, therefore caution should be exercised when comparing data prior to 2006. In November 2007 the amended General Order, Domestic Violence was promulgated. This General Order defines the philosophies, principles and standards for the prevention of domestic violence and repeat victimisation. This initiative may have had some impact on the increase in assaults during 2008.
63 Mandatory reporting on 'reportable' assaults (unlawful sexual assault, unreasonable use of force or assault) in a residential care facility became effective 1 July 2007.
64 While assault is defined in legislation, the definitions of an offence at common law are relied upon.
65 South Australia does not record an assault or any other offence (when evidence suggests an assault or another offence has taken place) if they cannot locate a victim or their representative.
66 The South Australian Domestic Violence Act 1994 was amended in 2001 (stalking) and in 2004 (problem gambling family protection orders).
67 South Australia record all family and domestic violence related assaults even if the victim does not want to proceed.
68 Sexual assault counts may include incidents committed prior to the reference period but reported to police in that reference period. The Mullighan enquiry (spanning December 2004 to April 2008) into the sexual abuse of children in state care has generated renewed and continued public awareness resulting in increased reporting of offences committed prior to 2007. In 2008, approximately 5% of sexual assaults reported to the police related to incidents occurring prior to 2008; for 2007 it was approximately 10%.
69 Leaving restaurants without paying and failing to pay for petrol form part of the offence category of other theft for this collection. Prior to 2006, these offences were not included in other theft counts, but may have been recorded against other theft categories not in scope of this collection. Taxi fare evasion forms part of fraud and is out of scope of this collection. From 2006, Taxi fare evasions are included in other theft as these cannot be separated out.
70 South Australia Police record a single victim in instances where multiple vehicles belonging to that victim are stolen in a single incident. Victims of motor vehicle theft may therefore be understated. However, impact to victim counts is minimal.
71 The reduction in other theft offences from 2003 to 2004 may have been the result of the maturation of the decentralised Local Service Area structure, the South Australia policing model, the Performance Outcome Review process and the setting of reduction targets.
72 The legal age of consent (that is, when it is legal for young people to consent to sex) for South Australia and Tasmania is 17 years of age. The legal age of consent in all other states and territories is 16.
73 The following initiatives were in operation in South Australia:
74 As part of the focus on remote communities and the recommendations of the Gordon Inquiry in 2002, a number of multifunctional police facilities have been established in remote Western Australia in the last five years: one in 2003 in the Central Desert; three in 2004 in the Kimberley and one in the Central Desert; one in 2006 in the Central Desert; one in 2007 in the Pilbara and two in the Kimberley, plus a police post in the Kimberley.
75 The Western Australian Acts Amendment (Family and Domestic Violence) Act 2004 came into effect on 1 December 2004. Police have a statutory obligation to investigate if they have a 'reasonable suspicion' that a person is committing an act of family and domestic violence, that is also a criminal offence, or has put the safety of a person with whom they have a family or domestic relationship at risk. The definition of a 'family and domestic relationship' is very broad and the definition of an 'act of family and domestic violence' provides broad grounds for intervention. Western Australia records all family and domestic violence related assaults even if the victim does not want to proceed.
76 In 2004, significant changes were made to the Restraining Orders Act 1997, the Criminal Code, and the Bail Act 1982, to improve the way police respond to and report domestic violence. Prior to 2004, family and domestic assaults comprised around 25% of total reported assaults; from 2004 to 2007 the proportion has consistently been around 38% of total reported assaults.
77 Western Australia does not record an assault or any other offence (when evidence suggests an assault has taken place) if they cannot locate a victim or their representative and when the evidence suggests that the assault is minor.
78 Sexual assault counts may include incidents committed prior to the reference period but reported to police in that reference period.
79 There had been a significant increase in the use of DNA testing (and media advertising of this fact) in 2006. This may have acted as a deterrent for offenders and therefore may provide some explanation for the decrease in some offence categories during 2006.
80 A new offence recording system, the Incident Management System (IMS), was implemented and rolled-out between September 2002 and August 2004, and gradually replaced the Offence Information System (OIS) over that period.
81 The blackmail/extortion data may be understated prior to 2003 as the previous recording system was unable to include those offences related to blackmail/extortion with no monetary influence. The IMS is able to provide both pecuniary and non-pecuniary offences for extortion.
82 The increased re-licensing of second-hand vehicles resulted in a significant increase in immobilisers being fitted to old vehicles. This may have contributed to the decrease of motor vehicle theft from 2003 to 2004. In December 2006, 77% of all registered vehicles in WA had immobilisers fitted, while the national average was 54% (Source: National Motor Vehicle Theft Reduction Council 2007).
83 A number of strategies have been implemented to combat crime. These include:
84 The Family Violence Act 2004 came into effect on 30 March 2005 and is the legislative basis under which Tasmania Police operates in matters of family violence. Family violence means any of a number of specified types of conduct (including assault and sexual assault) committed by a person, directly or indirectly, against that person's spouse or partner (including ex-spouse or ex-partner), including same-sex relationships. The legislation provides enhanced police powers in relation to entry, search and arrest in family violence cases and mandates certain professions (doctors, dentists, psychologists, teachers, etc.) to report to Police the occurrence or suspicion of family violence. Assaults relating to family violence are recorded even if the victim does not want to proceed. This has resulted in a sharp increase in assaults recorded in 2005 followed by a gradual decline.
85 Sexual assault counts include incidents committed prior to the reference period but reported to police in that reference period; 29% of sexual assaults reported in 2006, 33% reported in 2007 and 26% reported in 2008 related to earlier time periods.
86 Prior to 2005, all counts of demanding property with menaces were included in the category of robbery. From 2005 (revised data), these offences were either classified to robbery or blackmail/extortion, depending on the circumstances of the incident.
87 A motor vehicle theft is recorded even if later it is determined that the motor vehicle had not been stolen.
88 The legal age of consent (that is, when it is legal for young people to consent to sex) for South Australia and Tasmania is 17 years of age. The legal age of consent in all other states and territories is 16.
89 The following are examples of some initiatives/programs which were in operation in Tasmania:
The Northern Territory
90 A number of new initiatives were introduced by Northern Territory Police during late 2006 and 2007 and this has influenced the rate of change for some offence types, particularly assault. Caution should therefore be exercised in interpreting data movements between 2006 and 2007.
91 The rise in assault counts between 2006 and 2007 can be largely attributed to three key factors: a change to the NT IT system and business practices, the implementation of the NCRS and training associated with it and continued local domestic violence initiatives.
92 The Northern Territory Police IT system - PROMIS Case Management System - was significantly upgraded in April 2007. Internal business practices were also reviewed to improve the quality assurance of the information being recorded by police in the Northern Territory, particularly for the more serious offences. This review highlighted a number of areas for improvement and a number of system improvements, including the introduction of mandatory fields, and improvements to business practices, were made to improve the quality of information being recorded about offences and victims from early 2007. These improvements were expected to increase the recording of offences during 2007 and in 2008.
93 The NCRS was introduced May 2007. This initiative was combined with the enhancements mentioned previously, and there was a concerted effort in training police personnel in the new procedures.
94 The Northern Territory Domestic Violence Act 1992 was last amended in October 2005. It provides a broad definition of 'domestic relationship'. A General Order issued to Northern Territory Police in November 2005, Domestic Violence - Response, Investigation and Prevention, sets out processes and procedures for police response to, and investigation of, domestic violence incidents and related criminal offences. It details procedures for initiating civil and criminal action in these matters, including 'taking positive action in every case even where victims are reluctant to act'. All family and domestic violence related assaults are recorded even if the victim does not want to proceed. In July 2008 amendments to the Domestic Violence Act 2007 saw a broadening of the definition of 'domestic relationship'. In addition to these changes the 2008 review of the Violent Crime Reduction Strategy had seen a slight rise in offences.
95 Domestic violence remains a high priority for service evidenced by the formation of the Domestic and Personal Violence Protection Units, the Peace at Home Project in Katherine and the training of all operational members in related issues, and the enhanced domestic violence investigation training provided to key members in investigative, supervisory and support positions. As a result of this there is concerted effort by police to encourage victims to come forward to police.
96 The large increase in assault victims from 2004 to 2005 was significantly related to the introduction of domestic violence initiatives in the Northern Territory in 2005. The rise in assaults from 2005 to 2006 and 2006 to 2007 continue to be influenced by these domestic violence initiatives, however, non-domestic violence assaults also significantly increased during 2007. The initiatives mentioned previously have influenced this direction.
97 Assault in the Northern Territory is clearly defined under sections 187-188 of the NT Criminal Code Act and therefore does not rely on common law definitions.
98 If after a report of an assault further investigation reveals, insufficient evidence, but in the judgement of a police officer a crime did take place, a record of an assault will still be made on the Northern Territory Police administrative recording system (PROMIS) with an outcome code of 'insufficient evidence'.
99 Sexual assault counts may include incidents committed prior to the reference period, but reported to police in that reference period.
100 A number of strategies exist in the Northern Territory to reduce crime:
The Australian Capital Territory
101 During 2007 and continuing into 2008, ACT Policing targeted anti-social behaviour related to intoxication in public places through greater police presence, particularly during peak times. The increased visibility of and accessibility to police, through ongoing initiatives such as the Suburban Policing Strategy and Operation Cobalt, may have increased the likelihood of assault offences being reported to police.
102 The targeting of repeat offenders through the establishment of permanent Property Crime teams in June 2006 may have contributed to the decrease of UEWI for 2007.
103 The Property Crime Reduction Strategy is one of many factors that may have contributed to a decrease in motor vehicle theft in 2007. The improved security features in modern cars, greater uptake of the immobiliser rebate offered by the ACT Government and improved security in shopping centre car parks have also been contributing factors in influencing the decrease from 2006 to 2007.
104 Motor vehicles that are stolen in the Australian Capital Territory, but recovered in another state/territory are recorded on the Australian Capital territory operational IT systems and included in the counts.
105 The Australian Capital Territory amended the Domestic Violence & Protection Orders Act 2001, with amendments coming into force in March 2005. Some definitions have changed, including the definition of what constitutes a 'domestic partner', which has been extended. These definitional changes were not expected to impact on the type or rate of offences recorded on Australian Capital Territory operational IT systems. The decision to charge is made by investigating police based on the evidence available to them.
106 Sexual assault counts may include incidents committed prior to the reference period but reported to police in that reference period. In 2007, 7% of total sexual assaults related to victims who reported an offence more than a year after the initial offence occurred.
107 An upgrade of the ACT policing IT system - PROMIS Case Management System (CMS) - was introduced on 29 November 2005 resulting in significant change to the way in which offences were recorded in the Australian Capital Territory. Data prior to November 2005 were mainly based on the primary victim (often the complainant) as only one victim's details could be recorded against a particular offence. In the new version of the CMS, offences now can have multiple victims recorded against them. Data for 2006 onwards is a more accurate reflection of the number of victims associated with reported offences. As a result of these IT changes, data prior to 2006 may not be strictly comparable for person-related offences such as assault, sexual assault and robbery and therefore comparisons with previous years should be interpreted with caution.
108 Care should be also taken when comparing UEWI data prior to 2006 as a number of data quality improvements associated with the update of the CMS have been made to this offence category which has seen a redistribution between 'UEWI - property' and 'UEWI - other'. Data are not comparable to previous years.
109 In 2006, there were an unusually high number of armed robberies in a short period of time committed by a small number of offenders or offence groups.
110 The offence categories used for national crime statistics in this publication are based on ASOC 1997. The ASOC was implemented in the recorded crime statistics collection from 1 January 1999 and provides a uniform national statistical framework for classifying offences. The national offence definitions are descriptive and may not correspond with legal or police offence definitions in a particular jurisdiction. For further information on the mapping of national offence categories to the ASOC 1997 see Appendix 1.
111 The ABS released a revised edition of the ASOC in 2008. The revised ASOC is likely to be implemented for the 2009 reference period.
112 The following provides an explanation as to how victims are treated and counted in this collection.
113 Data are compiled on the basis of the date an offence is reported to police and recorded within a reference period. This corresponds to either the date the offence was reported to police by a member of the public or when it was detected by police. The report date may not necessarily be the date when the offence occurred. This is particularly the case for homicide and related offences and sexual assault offences, where in some instances the time difference between when the offence(s) occurred and the report/detection date may be substantial.
114 A victim of a criminal incident is classified to the most serious offence of one of the offence categories in scope of this collection (see paragraphs 3-10 for offences in scope). Victims of multiple offences may be counted more than once if the offences fall into separate ASOC divisions. The most serious offence within an ASOC division is the one with the lowest ASOC code. For example, Murder (0111) is a more serious offence than Manslaughter (0131).
115 A victim can be a person, premises, organisation or motor vehicle depending on the type of offence.
Counting within an ASOC Division category
116 If multiple offences per victim fall within the same ASOC division the victim is counted only once to the most serious offence within that division.
117 Examples of where a victim of multiple offences would be counted once in the same ASOC division are:
118 For the offence of UEWI the following applies:
Counting across national offence categories
119 If a victim is subjected to multiple offences during the same criminal incident the victim may be counted more than once. If the multiple offences fall under different ASOC divisions then the victim will be counted under the most serious offence of each relevant ASOC division category. For example, a person kidnapped and murdered will be counted twice under the national counting rule; once in the kidnapping/abduction ASOC category and once in the murder ASOC category.
120 Rates for the general population are presented in tables 2.1 and 2.3. Rates are expressed as victims per 100,000 of the Estimated Resident Population (ERP). As the population changes over time, the denominator used for the calculation of rates will vary, depending on the reference period and therefore data will be revised accordingly. The ERP for the midpoint of each reference period is used to calculate the rates. Rates expressed per 100,000 persons generally accord with international and state and territory practice.
121 The formula for calculating rate per 100,000 persons is: No. of reported victims / Estimated Resident Population x 100,000
122 The ERP series are revised every five years to incorporate additional information available from the latest Census of Population and Housing. Except for the Indigenous victimisation rates, the rates and indexed rates presented in this issue have been calculated as follows:
123 For population estimates and information on the methodology used to produce ERP, see Australian Demographic Statistics (cat. no. 3101.0). For Recorded Crime - Victims data, all estimates and projections for the Australian Capital Territory exclude Jervis Bay Territory. All estimates and projections for Australia exclude the external territories of Christmas Island and the Cocos (Keeling) Islands.
124 The risk of victimisation varies depending on the age and sex of the victim. This publication includes details of the age and sex of the victim, and age and sex specific victimisation rates. Rates are calculated using estimates of the age and sex breakdown of the population. For the offence categories of robbery and blackmail/extortion, where the victim may be a person or an organisation, victimisation rates have been provided for person victims only.
Indigenous victimisation rates
125 Indigenous victimisation rates are expressed per 100,000 Indigenous population. Rates for the Indigenous population in this publication are based on the low series projections for 30 June 2008 from Experimental Estimates and Projections, Aboriginal and Torres Strait Islander Australians, 30 June 1991 to 30 June 2009 (cat. no. 3238.0). These projections are based on the 2001 Census of Population and Housing. New series of Indigenous population projections are scheduled for release in late 2009 and will be based on the 2006 Census of Population and Housing.
126 The low series are one of two series of these projections that have been published for the years 2002 to 2009.
127 Rates for the non-Indigenous population are calculated using the total ERP for the state or territory minus the projected Indigenous population.
128 Care should be exercised in interpreting rates based on small numbers of victims.
129 An index is a convenient way of comparing values over time. The index allows comparison of two values of recorded crime for a common offence within a jurisdiction. Indexes are provided to assist in interpreting change over time within jurisdictions. Indexes should not be used to make direct comparisons between jurisdictions.
130 In order to compare two values of recorded crime it is necessary to designate one of the time periods as the ‘reference’ period and setting its value to 100.0. (This period is referred to as the base period or year as it is the first period for constructing the index). The index for all other periods (i.e. the comparison values) is calculated by determining the ratio of the comparison period value to the reference period value and then multiplying by 100.0. For example, suppose the recorded crime rate was 200 victims per 100,000 persons for a particular offence at 2001 (period 1), and for 2002 (period 2) it was 300 victims per 100,000 persons. 2001 (period 1) would be designated as the reference value or base year giving an index of 100.0 (200/200x100). The index value for 2002 (period 2) or the comparison value becomes 150.0 (300/200x100). The movement between 2001 (base year) and 2002 (comparison value) would be 50%.
131 For this publication, the indexes refer to victimisation rates per 100,000 persons and 2001 has been selected as the base year.
132 Movements in indexes from one period to another can be expressed either as changes in index points or as percentage changes. Index rates are not published where the numbers are very small as apparent large movements can be misleading.
133 The data presented in this publication have been confidentialised to prevent identification of victims. Cells with small values have been randomly adjusted. These adjustments do not impair the value of the tables as a whole.
134 Statistics produced on the basis of date reported may be affected over time by lags in completing and/or processing some crime reports. Where offences reported in the reference year are not processed for inclusion in the national statistics until the following year, revised data are included in subsequent publications and noted accordingly. Revisions have occurred for Victoria, South Australia, Western Australia, Tasmania and the Australian Capital Territory.
135 The Estimated Resident Population used in calculating the rates has been updated, to use final rebased data for 2002 to 2006, and updated preliminary data for 2007. See paragraphs 120-124. Consequently, some historical rates have been revised from previous years, despite the victims count remaining stable.
COMPARISONS TO OTHER ABS DATA
136 Another major source of measuring crime is the ABS 2005 National Crime and Safety Survey which is complementary to the Recorded Crime - Victims collection. This survey collects information directly from individuals and households about their experiences of crime, the extent to which incidents of crime were subsequently reported to police and perceptions of neighbourhood problems and feelings of safety for a broad selected set of offences (see Crime and Safety, Australia, 2005 (cat.no. 4509.0)). The results of the next Crime and Safety Survey are expected to be released early 2010.
137 A further source of crime victimisation which measures peoples experience of violence, harassment and stalking is the ABS 2005 Personal Safety Survey. This survey is conducted by personal interview and provides detailed information collected from individuals about: their experiences of threats/attempts or actual physical assault or sexual assault; the type of perpetrator; experience of harassment and stalking; reporting of incidents to police; feelings of safety; and includes a range of characteristics about some of these incidents of violence (see Personal Safety Survey, Australia, 2005 (cat. no. 4906.0)).
138 As different methods are used, caution should be exercised in making any direct comparisons. The Information Paper: Measuring Crime Victimisation, Australia: The Impact of Different Collection Methodologies (cat. no. 4522.0.55.001) was released by the ABS in 2004. The main aim of this paper is to increase community understanding of the nature of crime measurement in Australia and why the findings from different data sources may differ. The paper outlines national crime victimisation statistics available from several different sources in the Australian context (including Recorded Crime - Victims) and draws comparisons between the statistics from these sources. The paper also describes methodological differences between survey sources and the possible impacts of the methodological differences between the survey vehicles.
COMPARISONS TO OTHER SOURCES
139 The statistics presented in this publication may be different from those published by police forces in individual states and territories. Different definitions of offences (see Glossary) and counting methodology (see paragraphs 110-117) will result in variations. National recorded crime victims statistics are compiled on a victim basis in that they count the number of victims for each individual ASOC division offence category, rather than the number of breaches of the criminal law.
140 National crime statistics are produced annually on a calendar year basis. The reference period for this publication relates to offences that have been reported to police between 1 January and 31 December 2008.
CONFIDENTIALITY OF TABULAR DATA
141 Table cells containing small values have been randomly adjusted to avoid releasing confidential information. Due to this randomisation process, totals may vary slightly across tables.
