Summary
In Australia, the state and territory governments are responsible for dealing with young people involved in crime. Most young people in the juvenile justice system are either supervised in the community or are unsupervised, but some are detained. This report presents information on the number of young people in detention in 2011 and describes recent trends in the detention population. 
Around 1,000 young people are in detention throughout Australia
On an average night in the June quarter of 2011 there were 1,055 young people in detention (Table 1). Over one-third (36%) were detained in New South Wales. Almost half (48%) of those in detention were unsentenced, and in most states and territories, between 43% and 68% were unsentenced. The exception was Victoria, where just 22% were unsentenced.
Rates of detention are stable
On an average night in the June quarter 2011, there were 0.35 young people aged 10–17 per 1,000 in juvenile detention throughout Australia, compared with 0.33 per 1,000 in the June quarter 2007. There was little change in the rates for unsentenced and sentenced detention.
Throughout the 4 years to 2011, detention rates were highest in the Northern Territory, where they ranged from 0.75 per 1,000 to 1.78 per 1,000, and lowest in Victoria, where they ranged from 0.10 per 1,000 to 0.16 per 1,000.
Indigenous young people are over-represented in all states and territories
On an average night in the June quarter 2011, an Indigenous young person aged 10–17 was 20 times as likely to be in unsentenced detention and 26 times as likely to be in sentenced detention as a non-Indigenous young person. 
This over-representation was highest in Western Australia, where an Indigenous young person aged 10–17 was 29 times as likely to be in unsentenced detention and 50 times as likely to be in sentenced detention as a non-Indigenous young person in the June quarter 2011. In the remaining states and territories for which an over-representation ratio could be calculated, an Indigenous young person aged 10–17 was between 18 and 22 times as likely to be in unsentenced detention and between 16 and 22 times as likely to be in sentenced detention as a non‑Indigenous young person. Levels of over-representation were not calculated for states and territories where there were fewer than 5 Indigenous or 5 non‑Indigenous young people aged 10–17 in detention.
Indigenous young people were over-represented throughout the 4 years, although the level of Indigenous over-representation fell for both unsentenced and sentenced detention.

1	Introduction
The juvenile justice system is the set of processes and practices for dealing with young people who are alleged to have committed an offence or who have been proven guilty of committing an offence. This system is based on the principle that young people who break the law can and should be rehabilitated. Consequently, juvenile detention is considered an option of last resort in all Australian states and territories, and alternatives to detention are available to courts for young people who are awaiting trial or sentencing or who are sentenced.
Consistent with the principle of detention as a last resort, most of the young people in the juvenile justice system are not in detention. Only 15% of those under juvenile justice supervision on any given day are in detention, with the remainder under community-based supervision (AIHW 2011). Young people in the juvenile justice system can also be unsupervised in the community. Nearly all of those in detention are male and around half are Indigenous, and young people from remote areas and from areas of lower socioeconomic status are over-represented (AIHW 2011).
Despite the relatively infrequent use of detention, the over-representation of particular groups, such as Indigenous young people, is concerning (House of Representatives Standing Committee on Aboriginal and Torres Strait Islander Affairs 2011). There has also been a change in the use of detention in recent years and now around half of those in detention on an average day are unsentenced (AIHW 2011).
As well as this report, the AIHW also publishes the annual Juvenile justice in Australia reports, which provide information on all young people under juvenile justice supervision (for example, AIHW 2011). This report presents more recent data on trends in the juvenile detention population in Australian states and territories. It also contains data on young people in detention in Western Australia and the Northern Territory, which is not available for the Juvenile justice in Australia reports. The Juvenile justice in Australia reports provide additional analyses on the length of detention as well as information on the remoteness and socioeconomic status of young people’s usual residences and more detailed information on the age of young people in detention.

1.1	Definition of a young person
In all states and territories, a child is deemed to have criminal responsibility if they are aged 
10 or older. Children under the age of 10 cannot be charged with a criminal offence in any state or territory in Australia. The age limit for treatment as a young person is 17 in all states and territories except Queensland, where the age limit is 16. This age limit refers to the age at which the offence was committed (or allegedly committed), which means that people who are aged 18 or older (17 or older in Queensland) when they (allegedly) commit an offence will be dealt with under the criminal legislation relating to adults. 
Although the age limit for treatment as a young person is 17 (16 in Queensland), it is possible for people who are 18 or older to be under juvenile justice supervision. First, they may have been apprehended for an offence that was (allegedly) committed when they were aged 17 or younger. Second, if they entered supervision when aged 17 or younger, they may continue to be supervised by the juvenile justice system once they turn 18; alternatively, they may be transferred to the adult correctional system. Third, in some states and territories, juvenile justice agencies may supervise young people aged 18 and older due to their vulnerability or immaturity. Additionally, young people in Victoria aged 18–20 may be sentenced to detention in a juvenile detention centre (rather than an adult prison) where the court deems appropriate (the ‘dual track’ sentencing system).
1.2	Types of detention
Young people in detention can be either sentenced or unsentenced. Usually, those who are unsentenced have been remanded in custody by a court until their next court appearance. However, it is possible in some states and territories for the police to place young people in juvenile detention until their first appearance in court (police-referred detention). Both young people who have been remanded in custody by a court and those who have been referred to detention by police are classed as unsentenced in this report. Only a small proportion of unsentenced young people in detention are not on remand—on an average day in 2009–10, only 4% of those who were unsentenced were in police-referred detention (AIHW 2011). Police-referred detention is not available in Victoria or Tasmania.

2	Data and methods
2.1	Detention data
This report was compiled using data from the AIHW’s Juvenile Justice National Minimum Data Set (JJ NMDS), which contains data up to and including 30 June 2010, and was supplemented with additional data on the number of young people in detention at midnight at the end of each month from July 2010 to June 2011. (For more information on the JJ NMDS, see AIHW 2011.)
These data differ from those published by the AIHW in the annual Juvenile justice in Australia reports in several ways. First, this report presents the average nightly population for each quarter, while Juvenile justice in Australia presents the average daily population for each year. Second, young people who are concurrently unsentenced and sentenced are classified as sentenced in this report, but are counted as both unsentenced and sentenced in Juvenile justice in Australia (these young people are counted only once in the total detention population). These differences are to ensure comparability between the JJ NMDS data and the end-of-month data, which is a count of the number of young people at midnight and does not distinguish young people who are serving a sentence from young people who are concurrently serving a sentence and are unsentenced for another matter.
These data also differ from those published by the Australian Institute of Criminology (AIC) in the Juveniles in detention in Australia reports. The two most recent AIC reports (Richards & Lyneham 2010; Taylor 2009) contain data from the AIHW JJ NMDS; these data are the number in detention on the last night of each quarter, while this report uses data for each night of the quarter (where the source of the data is the JJ NMDS) or for the last night of each month in the quarter to calculate an average nightly population for the quarter. Earlier reports published by the AIC contain end-of-quarter data supplied directly by the states and territories. 
Additionally, there are several data coverage issues specific to particular states and territories.
Queensland
End-of-month data for Queensland do not include young people in police-referred detention. 
Western Australia
Western Australia did not provide JJ NMDS data for the period covering 1 July 2008 to 
30 June 2010. Instead, end-of-month data for Western Australia were used for this period. 
Northern Territory
The Northern Territory did not provide JJ NMDS data for the period covering 1 July 2008 to 30 June 2010. Instead, end-of-month data for the Northern Territory were used for this period. 
2.2	Methods
Age
For data extracted from the JJ NMDS, age is calculated at the start of the relevant quarter unless the relevant period of detention began within the quarter, in which case age is calculated as at the start of that period of detention. 
A young person’s age can therefore vary across tables as age is calculated in respect to the type of detention being analysed. This means that for a particular age group, the total number of young people in detention may not be the sum of the number of young people in sentenced and unsentenced detention. 
For the end-of-month data, age is calculated as at the end of the relevant month. 
Average nightly population
For data that are extracted from the JJ NMDS, the average nightly population is calculated by summing the duration (in nights) of each period of detention that falls within the quarter and dividing the summed duration by 91, which is the number of nights in a standard year divided by the number of quarters in a year. 
Where no JJ NMDS data were available for the relevant quarter, the nightly averages were calculated by averaging the relevant end-of-month data provided by the states and territories. 
Legal status
Young people who are both sentenced and unsentenced on a particular night are classified as sentenced. The JJ NMDS includes periods of detention with ‘other’ legal status; these periods are not included in this report.
Rates
Population rates allow for the comparison of different groups and different states and territories while taking into account differences in population sizes. Because there are differences between the states and territories in the extent to which young people aged 18 and older can be detained in juvenile justice facilities, rates are restricted to those aged 10–17. 
The calculation of rates for Indigenous and non-Indigenous young people excludes young people with unknown Indigenous status.
The number of young people in detention on an average night during a quarter is rounded to the nearest person. The rate is calculated using the number on an average day before rounding. 
Rates are not calculated where there are fewer than five young people in the numerator due to a lack of statistical reliability.

Rate ratios
In this report, rate ratios are used to compare Indigenous and non‑Indigenous rates and to provide a measure of the level of Indigenous over‑representation. Rate ratios should be interpreted with caution where there are small denominators, rare events and rates that converge while declining. Crude rates are also presented to guide interpretation. 
Rate ratios are not calculated where one or both the rates has fewer than five young people in the numerator, due to a lack of statistical reliability.
Rounding
The average nightly population is rounded to whole numbers. Components may not sum to totals due to this rounding.
Rates were calculated using the unrounded average nightly population and are presented in this report to two decimal places. Rates calculated by using the average nightly population rounded to whole numbers may therefore differ slightly to the rates presented in this report.
Rate ratios were calculated using rates rounded to two decimal places.
Proportions were calculated using average nightly numbers rounded to whole numbers.
Numbers and rates displayed in figures are rounded as presented in the appendix tables.
3	Recent trends in detention
3.1	Key points
From the June quarter 2007 to the June quarter 2011, the juvenile detention population in Australia increased by 12% from 939 to 1,055 young people.
•	This increase occurred in both the unsentenced (5%) and sentenced (20%) populations.
•	The detention population increased in the Australian Capital Territory (up by 62%, 8 young people), Victoria (35%, 50 young people), Western Australia (33%, 50 young people), South Australia (20%, 10 young people) and New South Wales (12%, 40 young people).
•	The detention population decreased in the Northern Territory (down by 40%, 21 young people), Queensland (11%, 18 young people) and Tasmania (14%, 4 young people).
This increase did not occur in all states and territories over the most recent year.
•	Over this period, the detention population increased in the Northern Territory (up by 14%, 4 young people), Victoria (12%, 21 young people) and Western Australia (9%, 17 young people).
•	The detention population decreased in New South Wales (down by 11%, 45 young people) and Tasmania (7%, 2 young people).
•	There was little or no change in Queensland, South Australia and the Australian Capital Territory.
The national rate of detention remained relatively stable over the 4 years.
•	The national detention rate ranged from 0.3 to 0.4 young people aged 10–17 per 1,000 in juvenile detention on an average night from the June quarter 2007 to the June quarter 2011.
•	Detention rates were highest in the Northern Territory, ranging from 0.75 per 1,000 to 1.78 per 1,000, and lowest in Victoria, ranging from 0.10 per 1,000 to 0.16 per 1,000. 
•	There were increases in the detention rates in New South Wales, Victoria, Western Australia, South Australia and the Australian Capital Territory over the 4 years 
•	Detention rates decreased in Queensland, Tasmania and the Northern Territory over the 4 years. 
Unsentenced detention is common in most states and territories.
•	For most of the 4 years, at least half of those in detention were unsentenced in all states and territories except Victoria, where less than one-third were unsentenced.

3.2	Number in detention
There were 1,055 young people in juvenile detention on an average night in Australia in the June quarter of 2011—an increase of 12% from 939 young people on an average night 4 years before in the June quarter of 2007 (Table A7, see Figure 3.3). A 4-year high of 1,088 young people in detention was reached in the March quarter of 2010.
These 4-year national trends were not reflected in all states and territories. From the June quarter 2007 to June quarter 2011, the juvenile detention population decreased in the Northern Territory (down 40% from 53 to 32 young people), Queensland (down 11% from 158 to 140 young people) and Tasmania (down 14% from 29 to 25 young people) (Figure 3.1). In contrast, the population increased in the remaining states and territories: in the Australian Capital Territory (up 62% from 13 to 21 young people), Victoria (up 35% from 144 to 194 young people), Western Australia (up 33% from 150 to 200 young people), South Australia (up 20% from 51 to 61 young people) and New South Wales (up 12% from 341 to 381 young people).
Over the most recent year from the June quarter 2010 to the June quarter 2011, the detention population increased in the Northern Territory (up by 14%, 4 young people), Victoria (12%, 21 young people) and Western Australia (9%, 17 young people). The population decreased in New South Wales (down by 11%, 45 young people) and Tasmania (7%, 2 young people), with little or no change in the remaining states and territories.

3.3	Rate of detention
Although nationally the juvenile detention population increased over the 4 years, the rate of young people in juvenile detention remained relatively stable, with 0.33 young people aged 10–17 per 1,000 in juvenile detention on an average night in the June quarter 2007 and 0.35 per 1,000 in the June quarter 2011 (Figure 3.2). The detention rate decreased slightly over the most recent year, from 0.37 per 1,000 in the June quarter 2010. Detention rates were most volatile in the smaller jurisdictions: the detention rate ranged from 0.75 to 1.78 per 1,000 in the Northern Territory and from 0.26 to 0.67 per 1,000 in the Australian Capital Territory. Despite this volatility, the Northern Territory consistently had the highest detention rate throughout the 4 years. The detention rate was lowest in Victoria, where it ranged from 0.10 to 0.16 per 1,000. 
Over the 4 years from the June quarter 2007 to the June quarter 2011, the rate of detention increased in the Australian Capital Territory (from 0.29 to 0.50 per 1,000), Western Australia (0.62 to 0.77), South Australia (0.25 to 0.31) Victoria (from 0.10 to 0.15) and, New South Wales (0.37 to 0.38). Detention rates decreased in the Northern Territory (from 1.54 to 1.20 per 1,000), Tasmania (0.49 to 0.40) and Queensland (0.33 to 0.28).
Over the most recent year from the June quarter 2010 to the June quarter 2011 the detention rate for the Northern Territory and Western Australia increased (by 0.16 and 0.08 per 1,000, respectively) while it fell in Tasmania (by 0.06 per 1,000), New South Wales (by 0.07 per 1,000) and the Australian Capital Territory (by 0.03 per 1,000). The detention rate was stable in the remaining states.

3.4	Legal status
Over the 4 years from the June quarter 2007, the unsentenced population increased by 5% to reach 505 young people in the June quarter of 2011, while the sentenced population increased by 20%, to 549 young people (Figure 3.3). Throughout the period, around half of the juvenile detention population was unsentenced.
Despite the overall increase over the 4 years, both the unsentenced and sentenced detention populations were relatively steady over the most recent year, with little change in the total number in detention in Australia from the June quarter 2010 to the June quarter 2011. However, this pattern did not occur for all states and territories (see chapters 4 and 5).

Source: Tables A7, A17, A27.
In most states and territories, at least half the detention population was unsentenced throughout the 4 years from the June quarter 2007 (Figure 3.4). The exception was Victoria, where between 21% and 32% was unsentenced. Excluding Victoria, the proportion that was unsentenced in the most recent quarter ranged from 43% in the Australian Capital Territory to 68% in Queensland.
There was little change in the proportion that was unsentenced over the 4 years in the larger states, with no change in Victoria (22%), a decrease of 1 and 2 percentage points, respectively, in Queensland (69% to 68%) and New South Wales (53% to 51%), and a decrease of 3 percentage points in Western Australia (52% to 49%).
There was more fluctuation in the smaller states and territories—the proportion that was unsentenced over the same period decreased in Tasmania (from 66% to 52%),the Australian Capital Territory (from 77% to 43%) and the Northern Territory (from 62% to 44%), respectively, while it increased in South Australia (from 47% to 62%). 
From the June quarter 2010 to the June quarter 2011, the largest decreases in the proportion that was unsentenced were in the Australian Capital Territory (67% to 43%), Tasmania (74% to 52%), the Northern Territory (64% to 44%) and Victoria (28% to 22%). The proportion increased in South Australia (from 28% to 22%), while there was little change in the remaining states and territories.

4	Recent trends in unsentenced detention
4.1	Key points
The number in unsentenced detention increased for non-Indigenous young people but decreased for Indigenous young people.
•	The number of unsentenced non-Indigenous young people in detention increased by 28% from 197 in the June quarter 2007 to reach 252 young people in the June quarter 2011, while the number of unsentenced Indigenous young people decreased by 13% over the same period from 284 to reach 248 young people in the June quarter 2011.
•	Over the most recent year from the June quarter 2010 to the June quarter 2011, the non‑Indigenous population increased by 2% while the Indigenous population decreased by 5%. 
Most of those in unsentenced detention are in New South Wales, Queensland and Western Australia.
•	Over the past 4 years, around three-quarters of those in unsentenced detention were in one of these states. In contrast, only 10% were in Victoria.
The unsentenced detention population increased in some states and territories but decreased in others.
•	Over the 4 years from the June quarter 2007 to the June quarter 2011, there were increases in South Australia (58% to 38), Victoria (39% to 43), Western Australia (26% to 98) and New South Wales (7% to 194). There were decreases in Tasmania (down by 32% to 13 young people), Queensland (13% to 95) and the Australian Capital Territory (down by 10% to 9).
•	The unsentenced detention population decreased over the most recent year from the June quarter 2010 to the June quarter 2011 in New South Wales, Victoria, Tasmania, the Australian Capital Territory and the Northern Territory. It increased in the remaining states.
There was little change in the national rate of unsentenced detention for young people aged 10–17.
•	Around 0.2 young people aged 10–17 per 1,000 are in unsentenced detention on an average night throughout Australia.
•	The rate of unsentenced detention was highest in the Northern Territory throughout the 4 years, while it was lowest in Victoria. 
Indigenous young people were over-represented in unsentenced detention throughout the 4 years, although there was a decrease in the level of over-representation.
•	At the start of the 4 years, an Indigenous young person aged 10–17 was 34 times as likely to be in unsentenced detention as a non-Indigenous young person aged 10–17. By the end of 2010–11, this level of over-representation had fallen to 20 times.
4.2	Number in unsentenced detention
The unsentenced detention population increased by 5% over the 4 years from the June quarter 2007 to the June quarter 2011 (see Figure 3.3), driven by an increase in the non‑Indigenous population. Over the 4 years, the non-Indigenous population increased by 28% (from 197 to 252), while the Indigenous population decreased by 13% (from 284 to 248) (Figure 4.1). 
In the most recent year, the non-Indigenous population increased by 2% (5 young people), while the Indigenous population decreased by 5% (12 young people)—although again, there was some fluctuation during the year for both groups.

Few of those in unsentenced detention are aged 18 or older—between 5% and 8% over the 
4 years (tables A17 and A19). Although non‑Indigenous young people in unsentenced detention were more likely to be aged 18 or older than their Indigenous counterparts, there was a steady increase in the number of Indigenous young people in this age group over the 
4 years, from 7 young people on an average night in the June quarter 2007 to 18 in the June quarter 2011. In contrast, the number of non-Indigenous young people aged 18 and older changed little, from 18 young people in the June quarter 2007 to 20 in the June quarter 2011 (Figure 4.2). 
In a similar pattern to the 4-year trend, the number of Indigenous young people aged 
18 and older in unsentenced detention increased by 50% (from 12 to 18) from the June quarter 2010 to the June quarter 2011, while the equivalent non-Indigenous population decreased slightly from 22 young people in the June quarter 2010 to 20 in the June quarter 2011.
In contrast, for those aged 10–17 it was the non-Indigenous population that increased in unsentenced detention—by 30% from the June quarter 2007 to the June quarter 2011, from 179 young people to 232—while the Indigenous population decreased by 17%, from 277 to 230. However, the Indigenous unsentenced population aged 10–17 fluctuated over the 4 years, reaching a high of 304 in the March quarter 2008 and with a recent peak of 275 in the March quarter 2010. 
On an average night in the June quarter 2011, 49% of those aged 10–17 in unsentenced detention were Indigenous, compared with 61% 4 years before in the June quarter 2007. In contrast, 47% of those aged 18 or older on an average night in the June quarter 2011 were Indigenous—an increase from just 27% 4 years before (tables A12, A13, A15, A16, A18 and A19).

Throughout the 4 years, the proportion of unsentenced detainees that was male has remained around 90% (Table A17). Both the male and female unsentenced population increased over the 4 years from the June quarter 2007 to the June quarter 2011; by 5% for young men, or 22 young people, and by 4%, or 2 young people, for young women (Figure 4.3). Over the most recent year, the male population decreased by 12 young people to 455, while the female population increased by 4 to 51 young people, although both populations fluctuated somewhat.

Around three-quarters of the unsentenced detention population in Australia is located either in New South Wales, Queensland or Western Australia (Table A17). Over the past 4 years from the June quarter 2007 to the June quarter 2011, between 37% and 49% of the unsentenced population was in New South Wales, while between 13% and 23% was in Queensland and between 15% and 19% in Western Australia. In contrast, only between 6% and 10% was in Victoria. 
The unsentenced detention population increased in several states and territories over the 4 years, with the largest percentage increases occurring in South Australia (up 58% from 24 to 38 young people), Victoria (up 39% from 31 to 43 young people) and Western Australia (up 26%from 78 to 98 young people) (Figure 4.4). A smaller increase occurred in New South Wales (up by 7% from 181 to 194 young people), while there were decreases in Tasmania (down 32% from 19 to 13 young people), Queensland (down 13% from 109 to 95 young people) and the Australian Capital Territory (down 10% from 10 to 9 young people).
In the most recent year, the unsentenced detention population increased from the June quarter 2010 to the June quarter 2011 in South Australia (up by 41%, 11 young people), , Western Australia (15%, 13 young people) and Queensland (4%, 4 young people). There were decreases in the Australian Capital Territory (down by 36%, 5 young people), Tasmania (down by 35%, 7 young people), the Northern Territory (22%, 4 young people), Victoria (10%, 5 young people) and New South Wales (8%, 17 young people).

4.3	Rate of unsentenced detention
The rate of unsentenced detention remained the same over the 4 years, at 0.20 young people aged 10–17 per 1,000 in the June quarter 2007 and the June quarter 2011 (Figure 4.5). There was a slight decrease over the most recent year from 0.21 per 1,000 in the June quarter 2010. As expected due to small numbers, the smallest jurisdictions experienced the most fluctuations—in the Northern Territory, the unsentenced detention rate ranged from 0.37 per 1,000 to 1.13 per 1,000 over the 4 years, while in the Australian Capital Territory, it ranged from 0.18 to 0.46 per 1,000, and in Tasmania from 0.17 to 0.39 per 1,000. Despite this volatility, the rate of unsentenced detention was highest in the Northern Territory throughout the 4 years from 2007–08. Victoria consistently had the lowest rate of unsentenced detention, ranging from 0.04 per 1,000 to 0.09 per 1,000.

Over the 4 years from the June quarter 2007 to the June quarter 2011, the national rate of Indigenous young people in unsentenced detention ranged from 2.15 Indigenous young people aged 10–17 per 1,000 to 2.97 per 1,000, while the equivalent non-Indigenous rate remained between 0.08 and 0.11 per 1,000 (Table A20). During the same period, the national level of Indigenous over-representation (as shown by the rate ratio) fell from 34 times in the June quarter 2007 to 20 times in the June quarter 2011 (Figure 4.6). 
Indigenous young people were over-represented in unsentenced detention in all states and territories for which rate ratios were calculated—rate ratios are not published where the constituent rates have fewer than 5 young people in the numerator. Rate ratios for the Northern Territory are not published for any quarter, while rate ratios are unpublished for selected quarters for Victoria, Tasmania and the Australian Capital Territory.
Among the states and territories, the level of Indigenous over-representation was consistently highest in Western Australia, although there was a general downward trend over the 4 years. In the June quarter 2007, an Indigenous young person aged 10–17 in Western Australia was 48 times as likely to be in unsentenced detention as a non-Indigenous young person aged 10–17, while by June quarter 2011, this level of over-representation had dropped to 29 times. 
For most of the 4-year period, Tasmania had the lowest level of Indigenous over‑representation—ranging from 6 times to 17 times. For the remaining states and territories, rate ratios ranged from 11–25 in Victoria, 14–27 in South Australia, 25–51 in the Australian Capital Territory, 18–28 in Queensland and 20–31 in New South Wales.

5	Recent trends in sentenced detention
5.1	Key points
The number in sentenced detention increased for both Indigenous and non-Indigenous young people over the 4 years. 
•	The non-Indigenous population increased by 29% from 235 in the June quarter 2007 to 303 in the June quarter 2011, compared with 9% from 219 to 239 for Indigenous young people.
Most of those aged 18 or older in sentenced detention are non-Indigenous.
•	Throughout the 4 years, almost three-quarters of those aged 18 or older in sentenced detention were non-Indigenous. In contrast, among those aged 10–17, the number of Indigenous young people was consistently higher than the non-Indigenous young people. 
Most of those in sentenced detention are in New South Wales and Victoria.
•	Between 33% and 43% of those in sentenced detention during the 4 years were in New South Wales, while between 19% and 28% were in Victoria.
The sentenced detention population increased in most states and territories.

There were decreases in South Australia (15% to 23 young people), Queensland (10% to 45 young people) and the Northern Territory (10% to 18 young people).
The rate of sentenced detention for young people aged 10–17 increased slightly over the 4 years.
•	The national rate increased from 0.13 per 1,000 in the June quarter 2007 to 0.15 per 1,000 on an average night in the June quarter 2011. Rates of sentenced detention were highest in the Northern Territory and Western Australia, and lowest in Victoria.
Indigenous young people were over-represented in sentenced detention throughout the 4 years, although there was a decrease in the level of over-representation.
•	At the start of the 4 years, an Indigenous young person aged 10–17 was 34 times as likely to be in sentenced detention on an average night as a non-Indigenous young person aged 10–17. By the end of the 4 years, they were 26 times as likely. 
•	The level of over-representation was highest in Western Australia, where it remained around 50 times. There was a general downward trend in the remaining states and territories, although the level of over-representation remained high. 
5.2	Number in sentenced detention
The average nightly sentenced detention populations increased for both the Indigenous and non-Indigenous populations over the 4 years, although the percentage increase was greater for the non-Indigenous population. The Indigenous population increased by 9% from 219 young people in the June quarter 2007 to reach 239 young people in the June quarter 2011, while the non‑Indigenous population increased by 29% from 235 to 303 over the same period (Figure 5.1).

In contrast to the unsentenced detention population, the number of non-Indigenous young people in sentenced detention who were aged 18 or older was considerably higher than the number of Indigenous young people in this age group—on average, almost three‑quarters of those in this age group were non-Indigenous (tables A23 and A29). 
Both the Indigenous and non-Indigenous 18 and older populations increased over the 4 years from the June quarter 2007 to the June quarter 2011: by 10% (from 48 to 53 young people) for Indigenous young people and by 24% (from 123 to 153) for non-Indigenous young people (tables A23 and A26). 
The pattern was reversed for those aged 10–17, with the Indigenous population consistently outnumbering the non-Indigenous population—and in some quarters, the number of non‑Indigenous young people aged 18 and older actually outnumbered the number of non‑Indigenous young people aged 10–17 (Figure 5.2). The proportion of sentenced detainees aged 10–17 that was Indigenous ranged from 55% to 62% during the 4 years (tables A22 and A28).
Over the 4 years from the June quarter 2007 to the June quarter 2011, the number of non‑Indigenous young people aged 10–17 increased by 34%, from 112 to 150, while the number of Indigenous young people aged 10–17 in sentenced detention increased by 9% from 171 to 186 young people.

Throughout the 4 years, young men formed around 95% of the sentenced detention population (Table A28), which is higher than for unsentenced detention (Table A17). Over the 4 years from the June quarter 2007 to the June quarter 2011, the male population increased by 22%, from 432 to 525, while the female population increased by 1 from 24 to 25 (Figure 5.3).

Over the 4 years, between 33% and 43% of those in sentenced detention in Australia were in New South Wales (Table A28). In contrast to unsentenced detention, Victoria had the second largest sentenced detention population, with between 19% and 28% of the sentenced detention population. Between 14% and 19% were in Western Australia, while between 8% and 13% were in Queensland. 
Over the 4 years from the June quarter 2007 to the June quarter 2011, the sentenced detention population increased in the Australian Capital Territory (up 200% from 4 to 12 young people), Western Australia (up 42%, from 72 to 102 young people), Victoria (up 34%, from 113 to 151 young people), Tasmania (up 20%, from 10 to 12 young people) and New South Wales (up 17%, from 160 to 187 young people) (Figure 5.4). In contrast, the sentenced detention population fell in South Australia (down 15%, from 27 to 23 young people), Queensland (down 10%, from 50 to 45 young people) and the Northern Territory (down 10%, from 20 to 18 young people). 
The sentenced detention population increased in most states and territories over the most recent year from the June quarter 2010 to the June quarter 2011: in Tasmania and the Australian Capital Territory by 71% (5 young people in both in the Northern Territory by 80% (8 young people), in Victoria by 21% (26 young people) and in Western Australia by 3% (3 young people). There were decreases in South Australia (down by 36%, 13 young people), New South Wales (13%, 28 young people) and Queensland (4%, 2 young people).

5.3	Rate of sentenced detention
The national rate of sentenced detention remained relatively stable over the 4 years, with a slight increase from 0.13 young people aged 10–17 per 1,000 on an average night in the June quarter 2007 to 0.15 on an average night in the June quarter 2011 (Figure 5.5). The sentenced detention rate remained relatively stable over the most recent year from the June quarter 2010 to the June quarter 2011.
As with the rate of unsentenced detention, the rate of sentenced detention showed the most volatility in the Northern Territory, which also had the highest rate for most of the 4-year period, with rates ranging from 0.28 per 1,000 to 0.75 per 1,000. Western Australia had the second highest rate (except for two quarters where it had the highest rate), ranging from 0.24 to 0.38 per 1,000. As with unsentenced detention, Victoria consistently had the lowest rate of sentenced detention, ranging from 0.04 per 1,000 to 0.08 per 1,000. Over the 4 years from the June quarter 2007 to the June quarter 2011, the rate of sentenced detention increased in most states and territories, most notably in Western Australia, where it increased from 0.29 to 0.38 per 1,000, and the Northern Territory, where it increased from 0.42 to 0.66. There was a slight decrease in the sentenced detention rate in New South Wales and South Australia.

Nationally, the Indigenous rate of sentenced detention fluctuated over the 4 years from the June quarter 2007 to the June quarter 2011, ranging from 1.69 Indigenous young people aged 10–17 per 1,000 to 2.05 per 1,000, while the equivalent non-Indigenous showed little variation, ranging from 0.05 per 1,000 to 0.07 (Table A31). Over the same period, the national level of Indigenous over-representation (as shown by the ratio of the Indigenous and non-Indigenous rate) showed a downward trend, falling from 34 times in the June quarter 2007 to 26 times in the June quarter 2010 (Figure 5.6).
Indigenous young people were over-represented in sentenced detention in all states and territories in which rate ratios were calculated (Figure 5.6). Rate ratios are not published where the constituent rates have fewer than 5 young people in the numerator. Rate ratios for Tasmania, the Australian Capital Territory and the Northern Territory are not published for most or all quarters in the 4-year period, while rate ratios for Victoria are not published for selected quarters.
Throughout most of the 4-year period, the level of Indigenous over-representation was highest in Western Australia, where an Indigenous young person aged 10–17 was around 50 times as likely to be in sentenced detention as a non-Indigenous young person aged 10–17. There was a general downward trend in the level of Indigenous over-representation over the 4 years in the remaining states and territories. The level of over‑representation fell from the June quarter 2007 to the June quarter 2011 in South Australia (from 40 times to 16 times), Queensland (35 to 20 times), Victoria (32 to 22 times) and New South Wales (25 to 21 times).

6	State and territory trends
6.1	New South Wales
The number of young people in unsentenced detention in New South Wales rose from 181 in the June quarter 2007 to a high of 247 in the June quarter 2008 before falling to a low of 170 in the December quarter 2010 (Figure 6.1). At the end of 2010–11, there were 194 young people in unsentenced detention—half of the New South Wales detention population. The sentenced detainee population rose from 160 on an average night in the June quarter 2007 to a high of 225 in the March quarter 2010 before falling to 187 in the June quarter 2011. 
In contrast, the rate of unsentenced detention for those aged 10–17 remained higher than the equivalent sentenced detention rate throughout the 4 years. The unsentenced detention rate rose from 0.23 per 1,000 in the June quarter 2007 to a high of 0.31 in the June quarter 2008 (Figure 6.2). There was general downward trend in the remaining 3 years, although there was a second peak at 0.26 per 1,000 in the middle of 2010–11, before falling slightly to 0.23 at the end of 2010–11—the same as 4 years before. The sentenced detention rate rose steadily in the first 2 years from 0.14 per 1,000 in the June quarter 2007 to a high of 0.22 in the June quarter 2009 before falling to 0.15 in the March and June quarter 2011. 
At the end of the 4 years in the June quarter 2011, a young person aged 10–17 in New South Wales was 1.5 times as likely to be in unsentenced detention as to be in sentenced detention on an average night, which was a slight decrease from 1.6 in the June quarter 2007 (tables A20 and A30).

Both the Indigenous and non-Indigenous unsentenced detention populations fluctuated over the 4 years (Figure 6.3). However, there were more unsentenced Indigenous young people than non-Indigenous young people at both the start of the 4 years in the June quarter 2007 and at the end in the June quarter 2011. At the start of the 4 years, there were 97 unsentenced Indigenous young people in detention and 81 unsentenced non-Indigenous young people.  By June quarter 2011, there were 97 Indigenous young people in unsentenced detention and 93 non-Indigenous young people. Both the Indigenous and non-Indigenous population peaked in the June quarter of 2008, at 112 and 131, respectively, and both had lows in the December quarter of 2010, at 78 and 88, respectively
Although both the sentenced Indigenous and non-Indigenous populations increased from the June quarter 2007 to the June quarter 2011, neither population experienced a steady trend. The sentenced Indigenous population increased from 80 on an average night in the June quarter 2007 to 88 in the June quarter 2011, but with 100 or more young people in detention on an average night from the December quarter 2007 to the March quarter 2010, and a 4-year high of 113 in the June quarter 2010. The sentenced non-Indigenous population increased from 77 on an average night in the June quarter 2007 to 94 in the June quarter 2011, but averaged almost 110 young people on an average night from the June quarter 2009 to the December quarter 2010, with a high of 116 in the March quarter 2010.
For the first 2 years, the sentenced non-Indigenous group was the smallest of the four groups with around 20% of the detention population (tables A7, A11, A14, A21, A24). By the end of the 4 years, all four groups were similar in size.

6.2	Victoria
Throughout the 4 years, around 70% of those in detention in Victoria were sentenced (tables A7 and A17). The number of young people in sentenced detention fell from 113 in the June quarter 2007 to 90 in the December quarter 2008 before increasing to 151 in the June quarter 2011 (Figure 6.4).
In contrast, the unsentenced detention population remained relatively stable over the 4 years, ranging from a low of 31 in the June quarter 2007 to a high of 53 in the March quarter 2010, before falling slightly to 43 young people in the June quarter 2011.
Although there were more young people in sentenced detention than unsentenced detention throughout the 4 years, the rate of unsentenced detention for young people aged 10–17 was slightly higher than the rate of sentenced detention in most quarters (Figure 6.5). This is because most of those (around 70%) in sentenced detention during the 4 years were aged 18 or older (Victoria has a system in which young people aged 18–20 can be sentenced to a juvenile detention centre) (Table A29). In contrast, less than one-quarter of the unsentenced population were in this age group (Table A19). 
The unsentenced detention rate increased from 0.04 per 1,000 in the June quarter 2007 to 0.07 in the June quarter 2011. However, there were fluctuations over the 4 years—peaks occurred in the June quarter 2008, at 0.08 per 1,000, and the March quarter 2010 at 0.09 per 1,000. 
The sentenced detention rate had a more consistent upward trend over the 4 years, from 0.05 in the June quarter 2007 to 0.08 in the June quarter 2011. 
At both the start and end of the 4 years, a young person aged 10–17 in Victoria was slightly more likely to be in sentenced detention than in unsentenced detention—they were 1.3 times as likely to be in sentenced detention on an average night in the June quarter 2007 and 1.1 times as likely on an average night in the June quarter 2011 (tables A20 and A30). However, for most of the 4 years, a young person of this age was more likely to be in unsentenced detention than sentenced detention, with a high in the March quarter 2009, when a young person aged 10–17 was 1.4 times as likely to be in unsentenced detention.

Both the Indigenous and non-Indigenous sentenced populations increased over the 4 years, although the trends were dissimilar (Figure 6.6). The two unsentenced populations also had different trends, with the Indigenous group decreasing slightly over the 4 years while the non-Indigenous group increased. 
The sentenced non-Indigenous group was the largest of the four throughout the 4 years, with around 60% of those in detention (tables A7, A11, A14, A21, A24). Over the 4 years from the June quarter 2007 to the June quarter 2011, the sentenced non-Indigenous group increased from 98 young people to a 4-year high of 133 young people, although the population fell to 73 in the September quarter 2008 (Figure 6.6).
The sentenced Indigenous group, which was much smaller than the non-Indigenous group, fluctuated between 15 and 18 young people on an average night for the first 2 years before increasing to a 4-year high of 23 in the September quarter 2010. The population fell to 17 on an average night in the June quarter 2011.
The unsentenced groups did not show as great a difference in numbers as the sentenced groups. The unsentenced Indigenous population steadily increased from 6 in the June quarter 2007 to reach a peak of 14 in the March quarter 2010, but fluctuated in the following quarters, with 4 young people in detention on an average night (a 4-year low) in the June quarter 2011. The unsentenced non-Indigenous population increased from 25 in the June quarter 2007 to a 4-year high of 42 in the June quarter 2008 before falling in the following two quarters to a 4-year low of 23. It increased in the following quarters to reach 42 in the June quarter of 2010, with 40 on an average night in the June quarter 2011.

6.3	Queensland
Throughout the 4 years, between 51% and 69% of the detention population in Queensland was unsentenced (tables A7 and A17). 
The number of unsentenced detainees was at a 4-year high at the start of the 4-year period in the June quarter 2007 at 109 young people (Figure 6.7). It fell to a low of 65 in the September quarter 2008 before steadily increasing over the following quarters, 95 young people in unsentenced detention at the end of the 4 years.
The sentenced detention population increased from 50 in the June quarter 2007 to a 4-year high of 61 in the September quarter 2008 before falling to 39 in the March quarter 2009. The population remained relatively steady over the remaining quarters, with 45 in sentenced detention in the June quarter 2011.
As Queensland has few young people in detention aged over 17, the 4-year patterns for the rates of unsentenced and sentenced detention for those aged 10–17 (Figure 6.8) are similar to the patterns for the total number in detention (Figure 6.7). In the June quarter 2007, there were 0.23 young people aged 10–17 per 1,000 in unsentenced detention and 0.09 per 1,000 in sentenced detention (Figure 6.8). By the June quarter 2011, the unsentenced detention rate had fallen slightly to 0.19 per 1,000, while the sentenced detention rate remained the same (although both rates fluctuated throughout the 4 years).
Throughout the 4 years, young people aged 10–17 were between 1.2 and 2.6 times as likely to be in unsentenced detention as sentenced detention (tables A20 and A30).

The Indigenous and non-Indigenous unsentenced populations showed somewhat similar trends for most of the 4 years, although they converged in the most recent year (Figure 6.9). The number of unsentenced Indigenous young people fell from 71 on an average night in the June quarter 2007 to a 4-year low of 38 in the September quarter 2008. The population then increased in the following quarters before experiencing a slight decrease in the most recent quarters, falling to 49 in the June quarter 2011.The unsentenced non‑Indigenous population fell from 37 in the June quarter 2007 to a 4-year low of 22 in the March quarter 2009. There was an upward trend in the following quarters, with a 4‑year high of 45 reached in the June quarter 2011. 
The sentenced populations showed a similar convergence over the 4 years. The sentenced Indigenous population fell from 31 on an average night in the June quarter 2007 to a 4-year low of 22 in the March quarter 2008 but increased to a 4-year high of 36 on an average night in the following two quarters (the opposite pattern to the unsentenced Indigenous population). There was a downward trend in the remainder of the 4 years, with the population falling to 25 in the June quarter 2011. The sentenced non-Indigenous population increased from 19 in the June quarter 2007 to a 4-year high of 30 in the June quarter 2008. Following a period of stability, the population decreased to a 4-year low of 13 in the June quarter 2009. In the following quarters, there was an overall upward trend, with the population increasing to 20 in the June quarter 2011.

6.4	Western Australia
Throughout the 4 years, between 46% and 59% of the detention population in Western Australia was unsentenced (tables A7 and A17). Both the unsentenced and sentenced populations increased over the 4 years, particularly in the latter half of the period (Figure 6.10). 
The unsentenced detention population increased from 78 young people on an average night in the June quarter 2007 to a high of 105 in the March quarter 2008. The population fell to 71 in the following quarters but over the next 3 years, there was a relatively steady increase to 98 young people on an average night in the June quarter 2011.
The sentenced detention population increased over the 4 years with some fluctuations. There were 72 young people in sentenced detention on an average night in the June quarter 2007 and 102 young people on an average night in the June quarter 2011, a 4-year high.
The unsentenced and sentenced detention rates for those aged 10–17 followed similar patterns to the overall population (Figure 6.10 and Figure 6.11), due to the low numbers of those aged 18 and older. The unsentenced rate increased from 0.33 young people aged 10–17 per 1,000 on an average night in the June quarter 2007 to 0.39 per 1,000 in the June quarter 2011, with a high of 0.44 per 1,000 in the March quarter 2008 and a low of 0.28 per 1,000 in the September quarter  2008 (Figure 6.11). The sentenced detention rate increased over the 4 years (with some fluctuations) from 0.29 per 1000 on an average night in the June quarter 2008 to a 4-year high of 0.38 per 1,000 in the June quarter 2011. 
At the start of the 4 years, a young person aged 10–17 in Western Australia was slightly more likely to be in unsentenced detention than in sentenced detention; by the end, they were almost equally as likely to be in sentenced detention (Figure 6.11).

Throughout the 4 years, the sentenced and unsentenced Indigenous groups were larger than the non-Indigenous groups (Figure 6.12). Only 6% of young Western Australians are Indigenous (Table A31), but on average, over one-third of the detention population was unsentenced and Indigenous, and a further one-third was sentenced and Indigenous (tables A7, A11, A21).

6.5	South Australia
For most of the 4 years, those in detention were more likely to be sentenced than unsentenced—on average, 53% of those in detention on an average night were sentenced (tables A7 and A27). However, by the end of the 4 years in the June quarter 2011, 62% of the detention population was unsentenced (tables A7 and A17).
The sentenced population increased over most of the 4 years: from 27 young people on an average night in the June quarter 2007 to a 4-year high of 44 in the December quarter 2010 (Figure 6.13). However, the sentenced population fell in the remaining two quarters to 23 young people on an average night in the June quarter 2011. 
In contrast, after an initial increase from 24 young people on an average night in the June quarter 2007 to 35 in the March quarter 2008, the unsentenced population had an overall stable trend, with some fluctuations, for most of the 4-year period. However the population increased from 27 to 38 over the most recent year.
The rates of unsentenced and sentenced detention for those aged 10–17 had similar trends to the overall detention population, although the sentenced rate was lower (Figure 6.14), as around 90% of unsentenced detainees were aged 10–17 years, compared with 70% for sentenced detainees (tables A18, A19, A28, A29). The unsentenced detention rate had an overall upwards trend, from 0.13 per 1,000 in the June quarter 2007 to 0.21 in the June quarter 2011. In contrast, the sentenced detention rate remained between 0.13 and 0.17 per 1,000 for most of the 4-year period, but fell from 0.16 to 0.09 per 1,000 from the June quarter 2010 to the June quarter 2011.
At the start of the 4 years in the June quarter 2007, a young person aged 10–17 in South Australia was slightly more likely (1.2 times) to be in unsentenced detention than in sentenced detention. By the June quarter 2011, this had increased to 2.3 times (tables A20 and A30).

Both the unsentenced Indigenous and non-Indigenous populations rose over the 4 years (Figure 6.15). The unsentenced Indigenous population increased from 10 young people on an average night in the June quarter 2007 to a 4-year high of 17 in the March quarter 2011, with 16 in detention on an average night in the June quarter 2011. The unsentenced non‑Indigenous population increased from 14 on an average night in the June quarter 2007 to reach a high of 23 in the September quarter 2009. It fell to a low of 13 in the June quarter 2010 but increased in the following quarters, with 21 in detention on an average in the June quarter 2011.
The sentenced Indigenous and non-Indigenous populations fluctuated over the 4 years. The sentenced Indigenous population rose from 15 on an average night in the June quarter 2007 to a 4-year high of 22 in the December quarter 2010 but then decreased to a low of 9 in the June quarter 2011. The sentenced non-Indigenous population increased from 12 in the June quarter 2007 to a 4-year high of 22 in the December quarter 2009, which also occurred in the September and December quarters of 2010, before falling to a 4-year low of 13 in the June quarter 2011.

6.6	Tasmania
For most of the 4 years, young people in detention were more likely to be unsentenced than sentenced, although the proportion fell over the 4 years from 66% of the detention population in the June quarter 2007 to 52% in the June quarter 2011 (tables A7 and A17). 
The unsentenced detention population fluctuated over the 4 years (Figure 6.16). There were 19 young people in unsentenced detention on an average night in the June quarter 2007 and 13 in the June quarter 2011, although the population peaked at 21 young people in the September quarter 2008 and again in the March and June quarters of 2009, and reached a low of 10 in the March quarter 2011. 
The sentenced population experienced similar fluctuations in the first part of the 4-year period, falling from 10 young people on an average night in the June quarter 2007 before falling to 9 in the September quarter 2008 and then rising to 14 in the June quarter 2009. Following this, there was a steady decline to 7 young people in the June quarter 2010, before an increase to 16 in the March quarter 2011, with 12 young people in sentenced detention on an average night in the June quarter 2011. 
For those aged 10–17, the rate of unsentenced detention was higher than the rate of sentenced detention throughout the 4 years, although both rates fluctuated throughout the period (Figure 6.17). The rate of unsentenced detention decreased from 0.33 per 1,000 in the June quarter 2007 to 0.24 in the June quarter 2011. There were peaks in the June quarter 2008 (0.38 per 1,000) and the September quarter 2009 (0.39 per 1,000), with a low of 0.20 in the March quarter 2011. The sentenced detention rate remained the same in the June quarter 2007 and June quarter 2011 at 0.17, with highs of 0.21 in the December quarter 2008 and 0.22 in the June quarter 2009 and lows of 0.12 per 1,000 in the September quarter 2008, 0.11 in the March quarter 2010 and 0.10 in the June quarter 2010.
On average, a young person aged 10–17 in Tasmania was almost twice as likely to be in unsentenced detention as in sentenced detention, and in the March and June quarters of 2010, they were over 3 times as likely to be in unsentenced detention (tables A17 and A27).

There were no clear relationships between the Indigenous and non-Indigenous sentenced and unsentenced population groups in Tasmania (Figure 6.18). 
The unsentenced non-Indigenous group, which was the largest of the four groups for most of the 4 years, decreased from 13 young people on an average night in the June quarter 2010 to 10 in the June quarter 2011, but fluctuated throughout the period. The unsentenced Indigenous group decreased from 7 on an average night in the June quarter 2007 to 3 in the June quarter 2011, but also fluctuated.
The number of sentenced Indigenous young people in detention changed little over the 
4 years, from 5 in the June quarter 2007 to 2 in the June quarter 2011, but reached a high of 8 in the December quarter 2008 and a low of 1 in the March quarter 2010. The number of sentenced non-Indigenous young people in detention increased from 5 young people on an average night in the June quarter 2007 to 10 in the June quarter 2011, with a high of 12 in the March quarter 2011.

6.7	Australian Capital Territory
Over the 4 years, most of those in detention on an average night in the Australian Capital Territory were unsentenced (tables A7 and A17), although the sentenced population increased over from 4 to 12 young people while the unsentenced population decreased slightly from 10 to 9. (Figure 6.19). The sentenced population reached a high of 12 in the December quarter of 2010 and the June quarter of 2011, while the unsentenced population reached a high of 18 in the September quarter of 2010.
For most of the 4 years, there were less than 5 young people aged 10–17 in sentenced detention so rates are not published due to a lack of reliability. The rate of unsentenced detention for those aged 10–17 showed a similar pattern to the overall population, due to the low number of those aged 18 and older in detention in the Australian Capital Territory (Figure 6.20). Over the 4 years, the unsentenced detention rate decreased slightly from 0.24 young people aged 10–17 per 1,000 on an average night in the June quarter 2007 to 0.23 per 1,000 in the June quarter 2011, with a low of 0.18 in the June quarter 2009 and a high of 0.46 in the September quarter 2011

The unsentenced Indigenous and non-Indigenous populations showed a slight upward trend in the most recent 2 years, while the sentenced Indigenous and non-Indigenous populations remained relatively stable (Figure 6.21).
The unsentenced non-Indigenous population decreased slightly from 6 young people on an average night in the June quarter 2007 to 5 in the June quarter 2011, with a high of 13 in the September quarter in 2010. The unsentenced Indigenous population increased slightly from 3 on an average night in the June quarter 2007 to 4 in the June quarter 2011, with a high of 9 in the December quarter 2010.
The sentenced non-Indigenous population fluctuated between 0 and 6 young people on an average night, while the sentenced Indigenous population fluctuated between 1 and 6 young people.

6.8	Northern Territory
Throughout the 4 years, around 60% of those in detention were unsentenced, although there were several quarters where the number of sentenced young people approached or exceeded the number of unsentenced young people (tables A7 and A17). 
The number of unsentenced young people fell during the first 2 years from a high of 33 on an average night in the June quarter 2007 to 14 in the June quarter 2011, although there was a peak of 27 in the March quarter 2011 and a low of 10 in the December quarter 2009 (Figure 6.22). The sentenced population fell from 20 on an average night in the June quarter 2007 to a low of 7 in the September and December quarters of 2009, but increased to 18 in the June quarter 2011, with a high of 20 in the March quarter 2011.
Because there were very few young people aged 18 and older in detention on an average night in the Northern Territory, the detention rates for those aged 10–17 (Figure 6.23) shared the same patterns as for the number in detention (see Figure 6.22). The unsentenced detention population fell from a high of 1.13 in the June quarter 2007 to 1.54 in the June quarter 2011, with a low of 0.37 in the December quarter 2009 (Figure 6.23). The sentenced detention rate increased from 0.42 per 1,000 in the June quarter 2007 to 0.66 per 1,000 in the June quarter 2011 with a low of 0.28 in the September and December quarters of 2008 and a high of 0.75 in March quarter 2011.

Between 90% and 100% of those in detention in the Northern Territory on an average night during the 4 years were Indigenous, so the overall detention trends closely resemble the trends of the Indigenous detention population (Figure 6.22 and Figure 6.24). There were 31 unsentenced Indigenous young people in detention on an average night at the start of the 4 years. This population fell to a 4-year low of 8 in the last quarter of 2009 before increasing to a 4-year high of 26 in the March quarter 2011. There were 13 in detention on an average night at the end of 2010–11. The sentenced Indigenous population fell from 17 on an average night at the start of the 4-year period to a 4-year low of 7 in the September and December quarters of 2008 before increasing to a 4-year high of 20 in the March quarter of 2011. There were 17 sentenced Indigenous young people in detention on an average night in the June quarter 2011.
The unsentenced and sentenced non-Indigenous populations remained between 0 and 3 on an average night over the 4-year period.

Notes
1.	The number of Indigenous young people in December each year is approximated by averaging of the two relevant 30 June Indigenous population projects; numbers may not therefore sum to the total.
2.	The number of Indigenous young people aged 10–17 years is approximated by summing the total number of Indigenous children aged 
10–14 years and three-fifths of the number of Indigenous young people aged 15–19 years. This method assumes that there is an even distribution of Indigenous young people in each single year of age between 15 and 19.
3.	The number of non-Indigenous young people is obtained by subtracting the number of Indigenous young people from the total number of young people.
