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:
Constants:
Interesting results:
- 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.
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.

A Model of the Rate of Adult and Youth Crime and Community Spending in Bourke:
This is a model which displays whether community spending and the number of police can affect both adult and youth in committing a crime and becoming involved in community activities.
The Underlying Assumptions:
It is assumed that adults and youths in the town of Bourke are the populations that we are interested in modelling. It is noted that a high number of people in Bourke are engaged in crimes. Therefore, people in Bourke are tempted or likely to commit petty crimes. Since petty crimes are not serious offences, both adults and youths who commit petty crimes will return to being adults and youths. However, if the crime is thought to be serious, people are sent to jail as a consequence. Once the people in jail serve their jail sentence, they are released from jail and returned to being themselves.
In addition, the community introduced community activities, such as football clubs to reduce the number of crimes. Adults and youths in Bourke can be engaged with community activities and then return to being themselves.
The variables of community spending and number of police are sliders which demonstrate the level of influence on different stocks and relationships when the number of police and community spending are adjusted. The simulation will reflect the adjusted pattern/trend. For example, if we hold community spending constant while adjusting the number of police, we see at one police officer, many people are committing petty crimes and not many are caught and placed in jail. However, if we change the number of police to 30, we can see a decrease in petty crimes and an increase in going to jail. Furthermore, if we change police to 60, almost no one is committing a petty crime and no one is sent to jail.
• There are no other influences besides community spending and the number of police.
• The number of police is negatively related to the amount of petty crime.
• People are not learning from past mistakes.
• Community spending is negatively related to the amount of petty crime, but positively related to engaging in community activities.
• All values and time period, concepts are made up for the purposes of the model and for simplicity. They do not reflect real-life figures or time periods.
• Initial values are as follow:
Bourke youth: 1000
Bourke adult: 1000
Bourke petty crime: 500
Bourke jailed population: 500
Explanation of the model:
This model begins with adults and youths engaging in petty crime. Petty crime activities may include theft, assault or disorderly conduct like domestic violence in adults. Petty crime or the more serious crimes that lead to jail are affected by the number of police, and amount of community spending. The number of police affects the amount of people getting caught committing a petty crime or placed in jail. In addition, if people are not caught or did not commit a serious crime, they are returned to being adults and youths.
Moreover, for the people in jail, they are sentenced for a period of 4 months before being released back to being themselves. This period of 4 months can vary for different crimes and does not represent the actual or real-life time period for any crimes.
It is assumed that the justice reinvestment plan in Bourke will have community activities like football clubs. The purpose of the plan is to reduce the amount of crime and people going to jail. Thus, people in Bourke are engaged in these activities for 4 months, during which it prevents people from committing a crime.

Justice Reinvestment in Bourke
A simple model of the township Bourke, showing the effects of community engagement within the youth population.
In-depth Explanation
This model uses the youth of Bourke and their temptation to commit crimes. These crimes are usually committed out of boredom and generally include: Breaking and entering, stealing, vandalism etc. The model depicts that the increase of police presents means that will be an increase of youths caught and convicted whilst also providing in the reduction in the temptation to commit a crime. Those youths that are caught and convicted are sent to juvenile detention where they undertake rehabilitation. Depending on this rehabilitation youths will either be released back into the community where they may attend school or youth activities or become bored again and re-commit or released back into a life of crime pending unsuccessful rehabilitation.
Taking into consideration the Justice Reinvestment plan some of the funds used to increase policing will be used instead to improve community development. This has a knock on effect on crime as there will be better youth activities running to keep youths engaged and free of boredom. This keeps youths out of juvenile detention and also encourages them to go to school.
School attendance also has an effect on the temptation to commit a crime, if a youth is attending school then they are less likely to be out and about committing crimes. It was noted by Bourke High school Annual report 2012 that their attendance was a little over 60%.
Upon simulation there are a number of graphs that have been generated, these include Crime & Detention, Crime vs School, Crime vs Youth Activities, Town, Detention & Youth Engagement and School vs Youth Activities. These graphs along with the variable sliders show what sort of impact increase and decreasing the variable will have on the town and the youth’s rate of crime and detention. These graphs can then be used to make a informed decision on where it’s best to spend the money of the Justice Reinvestment plan.
