This model displays the effects of youth crime and the influence of community expenditure, social support, and policing in the town of Bourke, NSW.

The traditional lifestyle for youth in this town involves either a chosen path of committing crimes, or, that of community activity and various forms of education.

The model has been designed to mimic a system where community expenditure and support services are adopted in order to inject a positive lifestyle for the youth population. The phenomena studied in this simulation is the balance between policing, community support and social influence versus not using them.

Assumptions
-1000 Youth Population

-Youth are either influenced by criminal activity or by productive educational activities.

- Adoption rate of community activities is influenced by personality, relating to current personal skill level of youth and willingness.

-If youth you do not become involved in community activity or some form of Education, then they turn to the path of crime.

-Punishment facility time is up to 12 months with a 2 year probation period

-Community expenditure and support only begins in the probation period, unless “Juvenile Support” slider is used.

-For the purpose of this study on youth crime and support before a crime is committed, we do not include a possibility of relapse in the rehabilitation phase.

STOCKS

• Youth
  
• Crime – all offences committed by those under 18
  
• Punishment Facility – juvenile detention
  
• Probation – release from punishment
  
• Education system – various programs
  

VARIABLES

Policing Units – Policing Bourke's criminal activity, and convicting after a crime has been committed.

Juvenile Support Units – The variable change in crime IF the community funds Support Units for youth before a crime is committed.

Social Support Units – The number of social support units available for released offenders during rehabilitation phase.

Community expenditure – the amount of time and money being spent on social services and policing.

Birth rate, crime rate, dicharge rate, recidivism & conviction rate

INTERESTING RESULTS

Slide any of the 3 variables to the extreme.

This model shows that adoption rate of a positive lifestyle is directly influenced by social influences.

1/ Juvenile Support Unit impact

Press Simulate.

Slide Juvenile Support Units to the extreme. Simulate again.

Juxtaposition of Juvenile Support impact on Behavior Graph shows that Crime and Reoffend rates drop significantly.  More people turn to law-abiding positive activity.

This will again all change with the manipulation of the Social Support unit slider…..

2/ Social Support Unit impact

Social Support Units only influence those released from the Punishment facility. The more social services on hand to support rehabilitation phase the less chance of committing crime for the second time, with Reoffend rates dropping significantly when the Social Support Units Slider is adjusted to the extreme.

Rehabilitation rates only increase marginally, in spite of more social support feeding into that phase.

The greatest impact is shown on Law-Abiding and Crime. How could this be? A logical conclusion is that there is a finite number of youth in the community and those who have received positive social support during a learning phase of rehabilitation, then go on to influence their friends, their family, and have a positive influence on those around them.

3/ Police Unit Impact

Slide Policing Units to the extremes. Simulate. Policing Units Graph shows there is a significant decrease in Reoffend rates, and a higher rate of Conviction.

Curiously, rehabilitation rates drop and crime rates go up. How could this happen? A logical conclusion is that conviction and punishment is not a crime deterrent. It needs the added influence of social support services for there to be a positive impact on decreasing criminal instincts and activity on the whole.

Conclusions

Social support and home visits need to happen in the flow between Youth Population and Crime - “Juvenile Support Units”.

Investment in youth via these juvenile social support officers before they commit an offence, limits the amount of criminal activity over time. So, crime effectively decreases with the direct influence of social services at a young age.

Equally, with more police presence in the community, for those tempted to re-offend, they have a deterrent.

The most efficient management of the community issues faced in Bourke however lies with a combination of both Policing and Social Support services at all levels within the community.

About the model

This model depicts crime patterns among the youth population of Bourke, within varying levels of policing expenditure, risk factor, rehabilitation expenditure and soccer club expenditure.

 

Underlying Assumptions:

1. Only the youth population of Bourke has the tendency to commit crime
   
2. No further external factors other than those presented have an effect on criminal tendencies
   
3. ‘Risk Factor’ refers to any factors that increase the likelihood of youths to commit crime. This may include exposure to domestic abuse, income level, education level, family background
   
4. No ‘jail effect’ -  jailed youths do not return to town being more corrupt than before through learning off their cellmates
   
5. Only 2 outcomes of participating in the soccer club: being engaged by the social activity and deterred from committing crime, or disengaged and become at risk of committing crime
   

 

Constants:

• Criminals have a 60% chance of getting convicted
  
• A jail sentence for convicted criminals is 6 months
  
• The top 20% of the most serious offenders get sent to the rehabilitation centre for 3 months, after which they return to town in a better state and less likely to repeat crime
  
• 1 session of the soccer club participation is 3 months
  
• Soccer club participants have a 10% chance of being disengaged
  
• Investments into policing, rehabilitation services and the soccer club are felt immediately – no time delay
  

 

Interesting results:

1. A high number of criminals does not necessarily mean they all end up in jail. A stimulation with risk factor at maximum (0.2) and policing at minimum (0.01) shows high numbers of criminals, but they all seem to be in town. When the slider for policing is adjusted to maximum (0.5), the criminals are moved from town to jail. Thus, a high investment in policing is needed to detect and detain criminals.
   
2. A generous investment into the soccer club (>0.35) results in a higher number of actively engaged and enlightened youths who then return back to town in a better state. This has an effect of bringing down the number of criminals (implications for long term)
   
3. In an ideal world, Bourke would invest maximum levels into policing, rehabilitation and the soccer club, and there would be a minimal risk factor for crime committing tendencies. A stimulation on these settings reflect few criminals, low jail rates and high engagement in the soccer club. However with the towns budget constraints, this is not a feasible solution for the long term.
   
4. Instead, a long term solution for Bourke (assuming a moderate risk factor of 0.1) is to allocate some of the policing expenditure (Eg. Down to 0.37) towards maximising community development services:
   

- The rehabilitation centre will tame the most serious offenders, making them less likely to commit crime the next time round (Eg. Setting at 1.0)

- The soccer club will distract youths from crime temptations, as well as nurture a sense of societal inclusion and wellbeing in the long term (Eg. Setting at 0.4)

A stimulation on these parameters show that criminal rates are moderated, the ratio of youths in jail to town is lowered, and the outcome for the soccer club is very good with majority of participants feeling engaged. 

Description:
This model focuses on the youth population of the community of Bourke in Australia. It shows the crime development of the youth population depending on the relationships of the expenditure provided by the police and community, crime rate and release rate of Bourke, and the rate of atonement failure.

​Initial Assumptions:

Youth in community: 1000
Mischievous youths: 200
Youth involved in crime: 140
Youth in jail: 80

How the Model Works:

1. Youth in Community
The model starts from being a youth in the community with no real motive which is affected by the community development expenditure. There are two paths that the youth can take, becoming bored of the community and staying as a normal youth with no motive in the community. There is a 70% chance of the youth becoming bored of the community and becoming mischievous as the community did not satisfy the youths' boredom.

2. Mischievous Youth
After transitioning to a normal youth to a mischievous youth, there are two paths that the mischievous youth can take. The non criminal activity path which is when the mischievous youth is not bored from the community anymore and proceeds back into the community, this path is affected by the community development expenditure. The second path is becoming involved with criminal activity and thus becoming a criminal, which is affected by the 40% crime rate of Bourke.

3. Criminal
After becoming a criminal youth, there are two paths that the youth can go down. The first path involves not being caught by the police yet and are still wondering around in the community at a 20% chance. This path is affected by the atonement failure variable as the criminal youth, despite going back into the community, is still willing to be involved in crime. The second path is getting caught by the police and is jailed at an 80% chance. This path is affected by the police expenditure used to catch the criminal youth.

4. Jailed
After being jailed by the police, the criminal youth can be released back into the community after their sentence has been completed, they can either still be involved in crime or a mischievous youth. The first path is failing to atone for their crimes even after spending a period of time in jail, with a 20% chance of happening. This path is affected by the atonement failure variable. The second path is being released back in the community at a 90% chance as a mischievous youth as they have learned their lesson in jail and will cease any criminal activities for the time being. After a period of time the released mischievous youth can take two paths, being involved with criminal activity again at a 40% chance or atoning for their crimes and becoming a non criminal youth with no ill-intentions at a 70% chance.

Simulation:

Relationship of Number of Criminal Youths and the Number Non-Criminal Youths:
This time series compares the number of criminal youths, mischievous youths, and non criminal youths for each following half year for 10 years in Bourke.

Number of Jailed Criminal Youths and Criminal Youths who have yet to be caught:
This time series compares the number of jailed criminal youths and criminal youths who have yet to be caught for each following half year for 10 years in Bourke.

Youths who have Failed to Atone and who have Atoned:
This time series compares the number of youths who have failed to atone after being released from jail and the number of youths who have been released from jail and have atoned Youths for each following half year for 10 years in Bourke.

​The Model

Justice Reinvestment in Bourke

Model Explanation:

One part of this model is displaying the typical lifestyle of many adults and youth in the town Bourke, North West of New South Wales. This lifestyle involves committing crime, getting arrested for the crime by police (or getting away with it) and spending time in jail (for adults) or juvenile detention (for the youth) or simply getting discharged.

Additionally to this traditional lifestyle being modelled, an alternative option called community groups has also been incorporated into the model. The model is showing that members of Bourke have the option to join a community group which the government hopes will improve their lifestyle when they are immersed once again into society, thus reducing the rate of crime.

The Stocks Involved:

Adult- The adults living in Bourke
Youth- The adolescents living in Bourke
Petty Crime- The standard crime committed by the youth of Bourke. This can include stealing cars and breaking into property.
Crime- The common crime circulating among the adults of Bourke. This includes domestic violence often as a result of heavy drinking.
Apprehended- Youth getting captured by the police
Arrested- Adults getting caught by the police
Juvenile Detention- Alienation of youth by police
Jail- Adults locked up by the police
Community Group- Groups formed for the people of Bourke to join. Includes development activities, sporting clubs and trade-skill learning classes.
Positive Lifestyle- Adults and youth who have improved themselves as a result of joining these community groups (the goal of community engagement program expenditure).

The Variables Involved and How to Adjust Them:

1. Policing: The number of police in the town of Bourke. The level and amount of punishment is dependent on the quantity of police present. 

Minimum amount is one as there should be at least one police existent.

2. Community Engagement Expenditure: The total amount of money spent into community groups to develop individuals. 

The purpose of the government is to spend money on community engagement activities so the minimum is at least one percent of the money they have available to spend and the maximum is 100 percent of the money they can afford to spend.

--> Both variables have a slider that goes up and down by one step. You can adjust both variables at the same time but take into account both variables have their own minimum and maximum.

Underlying Assumptions:

-Approximately 3000 people in Bourke

-Coefficients and initial values are arbitrarily chosen. These would be modified with real-life data.

-The only external influences on this model are police and community investment.

Suggested Settings for Interesting Results:

1. First move the policing and community expenditure sliders to their maximum. Hit the simulate button and look at the first time-series graph titled 'Youth Lifestyle'. Notice the delays between increase of each stock and the ordering: As Youth decreases, Petty Crime will increase. Then youth Apprehended will begin to increase followed by those going to Juvenile Detention. Youth will then start to increase again and the trend continues over the 3-year period displayed. Notice how the same pattern occurs for the time-series graph labelled 'Adult Lifestyle'.

2. Move the policing slider to 1 and the community expenditure slider to 100. Hit simulate. Notice in the 'Youth Lifestyle' graph how even with community expenditure at its maximum, over time, Petty Crime will still increase because there are hardly any police and hence hardly any youth getting caught so as a result the youth in Bourke keep to their regular immoral lifestyle. If you view the 'Adult Lifestyle' graph you will see the same pattern. (Note this point is a main reason for the conclusion drawn below).

3. Move the community engagement and policing slider to their minimum 1. Hit simulate. View the third display titled 'Community Engagement Program'. You will notice how Youth and Adult decrease and Crime and Petty Crime increase. Also, since community engagement is at its minimum too (not just policing) the amount of people in Community Groups decreases significantly and as a result the number of individuals creating a Positive Lifestyle for themselves decreases too.

4. Move the Community Engagement Expenditure slider to 1 and the Policing slider to 50 and look particularly at the last display labelled 'Adults and Youth: Membership and Crime Rates'. You will notice instantly how Community Group and Positive Lifestyle always have a lower number of individuals compared to the general Youth and Adult stocks as well as the Crime and Petty Crime stocks. This gives indication that a higher amount of investment should be put into the community engagement programs for better results. 

Conclusions:

A combination of policing and community engagement expenditure is the best solution for the people of Bourke as the policing will gradually reduce the amount of crime and the community development programs will help create a positive lifestyle for each individual that joins. Overall it is not efficient to just invest in community development programs. For the most effective outcome, an increase in policing is needed as well as investments in community engagement activities.

Note: You do not need to dive into any formulae. But feel free to move the sliders and hit that simulate button to view how the number of people in each stock changes based on the level of policing and community engagement expenditure!

MODEL EXPLANATION:

This model simulates possible crime patterns among the youth population of Bourke, where levels of alienation, policing and community engagement expenditure can be manipulated. Here the youth in Bourke have a minimum percentage of interest to participate in community activities in which the government aims to improve their lifestyle and therefore reduce the rate of criminal activity. ASSUMPTIONS:There are 1500 youths of Bourke in the population susceptible to committing crime and simulations of criminal tendencies are only based the factors presented, no external influences.
VARIABLES:“Alienation” includes any factors that can increase the likelihood of youths to commit crime such as exposure to domestic violence, household income, education level, and family background‘Community engagement Expenditure’ is the total monies budgeted into community activities to develop youths in and out of Juvenile detention‘Policing’ is the amount of police placed onto patrol in the town of Bourke to reinforce safety and that the law is abided by. STOCKS:Conviction rate is set to 60%A juvenile detention sentence for convicted criminals is set to 3 monthsThe top 30% of the most severe offenders are sent to rehabilitation for 3 months, to which they return to Bourke, assumingly in a better state and less likely to repeat a petty crimeCommunity activities are set to last for 3 months to align with the seasons: these could be sporting clubs or youth groupsCommunity participants have a 20% chance of being disengaged as it may not align with their interestsInvestments into policing are felt immediately& community engagement expenditure has a delay of 3 months
INTERESTING FINDS:1.    Alienation set to max (0.2), policing and community engagement set to minimum shows a simulation whereby all criminals are in town rather than being expedited and placed into juvenile detention, even after a base value of 200 youths placed into juvenile detention – this shows that budget is required to control the overwhelming number of criminal youths as they overrun Bourke2.    Set community activity to 0.01, policing to max & Alienation to max. A lack of community activity can produce high disengagement amongst youths regardless of police enforcement to the town of Bourke that has a high criminal rate. Juvenile detention only lasts for so long and not all youths can be rehabilitated, so they are released back into Bourke with chances of re-committing crime. 3.    Alienation plays a major role in affecting youths to consider committing crime. To keep criminal activity to a minimum, ideally the maximum rates of budget in policing and community engagement within youths highly at risk of committing crime should be pushed. Realistically, budget is a sensitive case within a small town and may not be practical. 4. Set policing to 0.25, community engagement to 0.2 & alienation to 0.04. Moderate expenditure to community activities and policing can produce high engagement rates and improved youths in the town of Bourke.

INTRODUCTION 

​This model simulates the effect of Police expenditure, Community expenditure and substance abuse (Alcohol and drugs).

This model can be used by community member responsible for making expenditure decision for the community. The variable can be manipulated for see how changes in community engagement and policing expenditure affect other parts of the community.

STOCKS-

Youth- The adolescents living in Bourke            

Adult- The adults living in Bourke

Crime- The common crime circulating among the adults of Bourke.

Apprehended- Getting captured by the police

Community Group- Groups formed for the people of Bourke to join. Including development activities, trade-skill learning classes and sports.

Positive Lifestyle- Adults and youth who have improved themselves because of joining these community groups and leading a positive lifestyle.

VARIABLE-

Community Expenditure - The amount of money spent on community groups to develop skills and keep the adults engaged. The variable can be raised to increase the amount of population (Adult or Youth) joining a community group which can lead to a positive lifestyle.

Alcohol and Drugs - This variable acts as an agent to disengage Adult and Youth from the community.

The Policing Expenditure - The number of money spent after police. This variable can be changed to affect the number of people getting apprehended.

ASSUMPTION- 

1) 3000 People living in Bourke

2) External Influence - Community groups, Police and Substance abuse

3) 70% of the population are Adult and 30% are Youth

4) Crime- 600

5) Apprehended - 

6) Community Group - 300

7) Positive life - 100

8) Jail - 480

SUGGESTED SETTING

Positive Lifestyle lead by the community-      Setting the Community Expenditure to a high 80, policing factor to a medium 50 and Substance abuse to a low 30 we will see a surge of positive lifestyle.

 

High Rate of Engagement- An increase in the Substance abuse variable to 10% shows crime and people in jail increase but the ratio of people engaged in community groups is much higher.

CRIME RATE (HIGHEST) - If Community Engagement Expenditure and Policing Expenditure are reduced to zero the amount of crime increases significantly over time and the amount of people in jail reduces to near zero.

 

CONCLUSION

A combination of policing and community engagement expenditure is the best solution for the people of Bourke.The policing will gradually reduce the amount of crime and the community development programs will help create a positive lifestyle.

For the most effective outcome, an increase in policing is needed as well as investments in community engagement activities.

This model simulates the possible rate of crime amongst youth in a small town called Bourke through the variable expenditures of community engagement and policing/punishment. The model shows how the youth population of Bourke have the choice to join in community activities

Background

 

The town of Bourke is located in far-west northern NSW. Although the population of Bourke is only approximately 3000 people, it has historically had the highest representation of youth crime rates and domestic violence related assaults within Australia (Milliken, 2018).

 

In 2013, the town implemented a community wide program that saw the diversion of funds from the prison system to a range of community initiatives in the area. This model focuses on the efforts driven towards youth development by the program.

Assumptions

 

1.    It is assumed that the youth population extends to anyone aged between 10-24. According to the ABS 2016 census, there are 368 residents aged between 10-24 in Bourke.

2. The retention rate in 2017 is 66%, which is a 33% increase since before the commencement of the project.

3. The high school attendance rate is 71%.

4. There was a 38% reduction in youth crime since the inception of the project.

5. There were 113 licences obtained through the Birang Driver Program, an 83% increase.

 

The outcomes of this model demonstrate the positive effects that reinvestment of funds  into community development programs can have on Australian youth, particularly Indigenous Australian Youth. Currently Indigenous Australian are grossly overrepresented in Australia incarceration rates with Indigenous youth representing almost 60% of the incarceration population, even though Indigenous youths aged between 10-17, make up on 5% of Australia’s total population (Calma 2016). NSW Health Minister, Brad Hazzard stated that the Maranguka Project demonstrates that to truly address this issue, “the solution has to be empowerment of the people themselves” (Milliken 2018). By having a strong understanding of the successful strategies implemented in Bourke, this can provide a model for other areas in Australia that face similar issues.

Bourke's Justice Reinvestment Options

Bourke consists of a community of 3000 people; 1000 being adults, and 2000 being youth.

This model presents the Youth and Adults from the Bourke and the estimated arrest rates for whether Bourke’s Justice Reinvestment program chooses to increase punishment for crime, or invest in prevention programs to help the community better themselves and avoid trouble. The overall aim is to reduce imprisonment.

Variables such as ‘Arrest rate for Increased Punishment for Youth’ and ‘Arrest rate for Increased Punishment for Adults’ are integrated to show the arrest rates over time when there is an increase in punishment and more policing. Variables such as ‘Arrest rate for Prevention for Youth’ and ‘Arrest rate for Prevention for Adults’ are integrated to show the arrest rates over time when preventative measures have been put in place. All variables are given an estimated rate, though the rate is not fixed and viewers are able to adjust the rates using the appropriate slider bars, as limited information has been provided at this given time in relation to the specified rates.

The slider bars for the youth have been given a range of -2000 to 2000 as the population of youth is 2000 and those are the limits. Same applies to the slider bars specified for the adults, though here the limit is from -1000 to 1000.

By setting parameter settings to a value lower than 0, you will start to see a decline in arrests. By setting the parameter over 0 you will see an increase. 

Stocks have been colour coded to represent their lines shown in the simulated graph.

The following insight shows the level of crime in the town of Bourke in comparison to the levels of Police and Community Engagement

This model displays the effects of youth crime and the influence of community expenditure, social support, and policing in the town of Bourke, NSW.

The traditional lifestyle for youth in this town involves either a chosen path of committing crimes, or, that of community activity and various forms of education.

The model has been designed to mimic a system where community expenditure and support services are adopted in order to inject a positive lifestyle for the youth population. The phenomena studied in this simulation is the balance between policing, community support and social influence versus not using them.

Assumptions
-1000 Youth Population

-Youth are either influenced by criminal activity or by productive educational activities.

- Adoption rate of community activities is influenced by personality, relating to current personal skill level of youth and willingness.

-If youth you do not become involved in community activity or some form of Education, then they turn to the path of crime.

-Punishment facility time is up to 12 months with a 2 year probation period

-Community expenditure and support only begins in the probation period, unless “Juvenile Support” slider is used.

-For the purpose of this study on youth crime and support before a crime is committed, we do not include a possibility of relapse in the rehabilitation phase.

STOCKS

• Youth
  
• Crime – all offences committed by those under 18
  
• Punishment Facility – juvenile detention
  
• Probation – release from punishment
  
• Education system – various programs
  

VARIABLES

Policing Units – Policing Bourke's criminal activity, and convicting after a crime has been committed.

Juvenile Support Units – The variable change in crime IF the community funds Support Units for youth before a crime is committed.

Social Support Units – The number of social support units available for released offenders during rehabilitation phase.

Community expenditure – the amount of time and money being spent on social services and policing.

Birth rate, crime rate, dicharge rate, recidivism & conviction rate

INTERESTING RESULTS

Slide any of the 3 variables to the extreme.

This model shows that adoption rate of a positive lifestyle is directly influenced by social influences.

1/ Juvenile Support Unit impact

Press Simulate.

Slide Juvenile Support Units to the extreme. Simulate again.

Juxtaposition of Juvenile Support impact on Behavior Graph shows that Crime and Reoffend rates drop significantly.  More people turn to law-abiding positive activity.

This will again all change with the manipulation of the Social Support unit slider…..

2/ Social Support Unit impact

Social Support Units only influence those released from the Punishment facility. The more social services on hand to support rehabilitation phase the less chance of committing crime for the second time, with Reoffend rates dropping significantly when the Social Support Units Slider is adjusted to the extreme.

Rehabilitation rates only increase marginally, in spite of more social support feeding into that phase.

The greatest impact is shown on Law-Abiding and Crime. How could this be? A logical conclusion is that there is a finite number of youth in the community and those who have received positive social support during a learning phase of rehabilitation, then go on to influence their friends, their family, and have a positive influence on those around them.

3/ Police Unit Impact

Slide Policing Units to the extremes. Simulate. Policing Units Graph shows there is a significant decrease in Reoffend rates, and a higher rate of Conviction.

Curiously, rehabilitation rates drop and crime rates go up. How could this happen? A logical conclusion is that conviction and punishment is not a crime deterrent. It needs the added influence of social support services for there to be a positive impact on decreasing criminal instincts and activity on the whole.

Conclusions

Social support and home visits need to happen in the flow between Youth Population and Crime - “Juvenile Support Units”.

Investment in youth via these juvenile social support officers before they commit an offence, limits the amount of criminal activity over time. So, crime effectively decreases with the direct influence of social services at a young age.

Equally, with more police presence in the community, for those tempted to re-offend, they have a deterrent.

The most efficient management of the community issues faced in Bourke however lies with a combination of both Policing and Social Support services at all levels within the community.
