3 Although national standards and classifications are used in the compilation of these statistics, some discrepancies remain between the states and territories. These are due to legislative and procedural differences between jurisdictions and the way that these differences are reflected in agencies' administrative data systems. As part of its quality assurance strategy, the ABS is working with corrective services agencies to minimise the effect of these differences.
4 The reference period for average daily prisoner population statistics and sentenced reception counts is the complete reference month. The reference date for all other figures is the first day of the reference month. However, not all states and territories report strictly according to this 'first day of the month' rule:
5 Calculation of figures for the entire quarter and entire year varies depending on the counting unit and method of counting prisoners:
6 The scope of the statistics in this publication includes all persons remanded or sentenced to adult custodial corrective services agencies (including Work Outreach Camps and Community Custody Centres in Queensland), or who are serving adult community-based orders in each state and territory in Australia.
7 Counts of prisoners in the following custodial facilities are included in the collection:
8 The prisons and community corrections collection excludes the following custodial facilities:
9 This collection includes counts of persons remanded or sentenced to adult custody facilities, or directed to serve community based orders administered by adult corrective services agencies. In all states and territories except Queensland, persons are considered adults if aged 18 years and over. In Queensland persons are considered adults if aged 17 years and over. The vast majority of persons counted in the collection are adults. However, juveniles may be included in exceptional circumstances.
10 Since December 2004, the Kariong Juvenile Correctional Centre in New South Wales has operated under the authority of adult corrective services. The population at Kariong Juvenile Correctional Centre may include adult persons as well as juveniles. New South Wales includes juveniles based in Kariong in this collection, however, this facility accounts for less than 0.5% of the New South Wales prisoner population.
11 Federal prisoners include those persons charged and sentenced under a Commonwealth statute, and those persons who are charged and sentenced under the laws of another country but transferred to an Australian prison to serve their sentence under the International Transfer of Prisoners Act 1997 (Cwlth). To give practical effect to this legislation in Australia, the framework was introduced in January 2003. For the purposes of this publication, federal sentenced prisoners are those persons who are recognised by the Criminal Law Division of the Australian Government Attorney-General's Department as having been charged and sentenced under a Commonwealth statute, or transferred from another country to serve their sentence in Australia.
12 With the exception of Victoria and Tasmania, community-based corrections includes those persons with breached or suspended orders.
13 Statistics in this publication are derived from information provided to the ABS from administrative records held by corrective services agencies within each state and territory. Statistics on federal prisoners are derived from records kept by the Criminal Law Division of the Australian Government Attorney-General's Department.
14 Statistics for persons held in custody are presented by the state or territory in which they were held and therefore may not be the sentencing jurisdiction. The only exception to this are data for federal sentenced prisoners. These are presented by the state or territory in which they were sentenced, not where they were held in custody.
15 Sentenced prisoners who have other offences that are unsentenced are counted as sentenced. Prisoners may be unsentenced because they are awaiting the outcome of their trial, convicted but awaiting sentence, or awaiting deportation.
16 If an offender has two or more different types of community-based orders operating simultaneously, then each order will be counted. If two or more community-based orders are of the same type, these orders together will only be counted as one order.
AUSTRALIAN CAPITAL TERRITORY PRISONERS
17 Persons sentenced to full-time custody by the Australian Capital Territory are usually held in New South Wales prisons. The Australian Capital Territory has two remand centres for unsentenced prisoners and a periodic detention centre. During 2000 the Australian Capital Territory commenced detaining prisoners sentenced for fine default only at their remand centres. Unsentenced Australian Capital Territory prisoners may also be detained in New South Wales prisons. A new custodial facility, the Alexander Maconochie Centre, opened in the Australian Capital Territory in September 2008. It is expected to begin accommodating prisoners from January 2009.
18 To provide greater understanding of the number of prisoners attributed to the Australian Capital Territory, while presenting an accurate picture of the New South Wales prisoner population, statistics relating to Australian Capital Territory prisoners in New South Wales prisons are presented as a subset of the New South Wales figures.
19 Imprisonment rate data for the Australian Capital Territory are included in the publication and are calculated on the basis of the total number of Australian Capital Territory prisoners (i.e. Australian Capital Territory prisoners held in New South Wales prisons, and Australian Capital Territory prisoners held in the Australian Capital Territory) divided by the estimated resident Australian Capital Territory adult population and multiplied by 100,000. For New South Wales, the imprisonment rate is based on the count of New South Wales prisoners, excluding Australian Capital Territory prisoners held in New South Wales prisons, divided by the estimated resident New South Wales adult population and multiplied by 100,000. Time series data have also been derived on this basis.
20 Imprisonment and community-based corrections rates enable comparisons of prisoner numbers to be made across states and territories. Prisoner and community-based corrections rates are expressed per 100,000 adult population. Imprisonment rates are calculated based on two different counting concepts (average daily and first day of the month), as a result there may be variations in imprisonment rates presented in this publication.
21 In this publication the population figures used in the calculation of rates are for persons aged 18 years and over for all states and territories except Queensland where the population is persons aged 17 years and over (see paragraph 9).
22 Rates for the total adult prisoner population and persons in community-based corrections are calculated using the estimated resident population (ERP) for each of the states and territories. All estimates for the Australian Capital Territory exclude Jervis Bay Territory. All estimates for Australia exclude the external territories of Christmas Island and the Cocos (Keeling) Island. As the population changes over time the denominator used for the calculation of rates varies, depending on the reference period. The most current ERP data available at the time of publication are used to calculate rates as follows:
23 The ERP series are revised every five years to incorporate additional information available from the latest Census of Population and Housing. The rates per 100,000 adult persons presented in this issue have been calculated using different ERP counts as follows:
24 For population estimates and information on the methodology used to produce the ERP, see Australian Demographic Statistics (cat.no.3101.0).
Indigenous imprisonment rates
25 Rates for the Indigenous adult population in this publication are based on the low series projections for 30 June of the relevant calendar year (refer to 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 2009 and will be based on the 2006 Census of Population and Housing.
26 The low series is one of two series of projections that have been published for the years 2002 to 2009.
27 The decision to use the low series as the denominator in the calculation of Indigenous imprisonment rates from 2002 followed consultation with the National Corrective Services Statistics Unit Advisory Group and other stakeholders.
28 The ABS is currently evaluating the use of the ABS Indigenous identification standard in Corrective Services agencies (both custodial and community-based corrections). Whilst the ABS has published Indigenous status data in Corrective Services collections for a number of years, quality assurance is required to better understand the level of accuracy over time.
29 The quality of the Indigenous status information collected and recorded in Corrective Services agencies is assessed against the ABS Standard Indigenous Question (SIQ). The SIQ is based upon self-identification by the individual who comes into contact with Corrective Services agencies. The SIQ requires individuals to be asked "Are you of Aboriginal or Torres Strait Islander origin?" The answers to the SIQ can be 'No', 'Yes, Aboriginal', or 'Yes, Torres Strait Islander'. If the offender is of Aboriginal and Torres Strait Islander origin, both responses should be identified. If an offender does not supply an answer to this question, or is not asked, the Indigenous status field should be recorded as 'not stated'.
30 As a result, the minimum output categories required in systems are:
31 For custodial corrections, initial indications are that corrective services agencies in all states and territories, with the exception of South Australia and Western Australia, ask the SIQ as described above.
32 There are however differences across the states and territories in relation to the recording processes for custodial data. In Tasmania, the Northern Territory and the Australian Capital Territory, individuals are asked the SIQ on each reception into corrective services custody, and it is mandatory to enter a response to this field in their recording systems. Victoria and Queensland do not re-ask the SIQ for every subsequent involvement that an individual has with corrective services, and data may also be sourced from other justice sources. In South Australia, it is a requirement for persons to be asked upon reception on each occasion in which they enter custody; however, it is not a mandatory field in their recording system. New South Wales does not have Indigenous status as a mandatory field in their recording systems and does not always re-ask the question for subsequent involvements. Western Australia does not currently comply with any component of the SIQ. For more information about Indigenous identification in community-based corrections refer to Appendix, page 36.
33 Some persons in custody are recorded with an unknown Indigenous status on the information systems of corrective agencies as their status has not been able to be obtained. Persons with Indigenous status unknown are excluded from tables 6, 7, 12 and 13. Counts of persons with an unknown Indigenous status are included in all other tables. Unknowns account for just over 1% of all records.
New South Wales
34 In March 2008, the administrative classification of the Wellington Correctional Centre was altered. The classification was changed from 'open' to 'secure' for 75% of the facility to reflect the change in the profile of inmates held. As such, the proportion of persons in secure and open custody altered in the March quarter 2008 compared to previous quarters.
35 The administrative classification of the following NSW correctional facilities was altered at 1 July 2005: Cooma, Dilwynia, Parramatta and Berrima. These facilities changed classification from 'open' to 'secure' to reflect alterations in the profile of inmates held, and the operational requirements of those centres. As such, the proportion of persons in secure and open custody altered in the September quarter 2005 compared to previous quarters.
36 The State government introduced an amnesty from February 2006 to May 2006 to encourage payment of unpaid fines. This resulted in a decrease in the number of persons serving a community-based order for fine default, particularly for the September quarter 2006.
37 In March 2006, Victoria opened Marngoneet Correctional Centre, Lara. The focus of this facility is to provide intensive treatment and offender management programs for males who have a minimum of six months of their sentence left to serve when they arrive there. The new Metropolitan Remand Centre at Ravenhall was opened in April 2006. The facility provides increased capacity to hold prisoners awaiting trial or sentencing.
38 On 1 July 2005 the Children and Young Persons (Age Jurisdiction) Act 2004 came into force in Victoria. This Act changed the definition of a child from a person under 17 years of age to a person under 18 years of age. As a consequence the definition of an adult also changed for corrective services data to a person aged 18 years and over. Imprisonment rates for the September and December quarters 2005, and March quarter 2006 have been revised as a consequence. Data prior to 1 July 2005 includes persons aged 17 years.
39 Quality assurance work conducted in Queensland during the September quarter 2007 resulted in the identification and elimination of duplicate and other records for the month of July 2007. Caution should be exercised when comparing data prior to the September quarter 2007.
40 The Corrective Services Act 2006 (Qld) commenced on 26 August 2006. One key provision in the new legislation relates to the management of offenders subject to Court-ordered Parole. This new order ensures that offenders serve 100% of their sentence under supervision, either in a correctional centre or under community supervision. This new order provides courts with the power to specify a parole release date for persons sentenced to a term of imprisonment of 3 years or less. Technical breaches of parole orders are no longer heard by a parole board and can often result in a person serving the remainder of their original sentence in custody. Court-ordered Parole is not available to sex offenders or serious violent offenders.
41 In September 2005 Queensland implemented a new offender management system - the Integrated Offender Management System (IOMS). As a result data for the September quarter 2005, December quarter 2005, and March quarter 2006 were revised in June quarter 2006.
42 Data on community-based correction orders extracted from the South Australian information system from the June quarter 2005 may be subject to data processing time lags.
43 Caution should be exercised when comparing community-based correction orders in Western Australia prior to the March quarter 2007 as data may have been slightly overstated.
44 In the June quarter 2005, Western Australia implemented a strategy to reduce the number of fine defaulters being taken into custody by offering alternative means of payment. This has resulted in a decrease in the number of sentenced receptions into custody for the September quarter 2005.
45 Tasmania was involved in a trial of new orders for bail, suspended sentences and drug treatment as part of the Court Mandated Diversion program (CMD) from 1 July 2007 to 30 June 2008. Counts for bail orders during the September quarter 2008 represent the transitional period concluding this trial.
46 The new Risdon Prison Complex in Tasmania was opened on 28 August 2006. This complex includes the Mary Hutchison Women's Prison which was opened in May 2006. A new men's maximum/medium security facility was also built within the complex.
Australian Capital Territory
47 In September 2005, home detention orders were discontinued as a sentencing and remand option in the Australian Capital Territory.
48 From 1 July 2005, Australian Capital Territory periodic detainees who were in breach of an order for more than three months were excluded from counts. Consequently, the periodic detainee population decreased.
