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!

Initial Values

600 alienated people

480 people committing crime

250 people arrested awaiting Trial

500 people in Jail

1000 people active in Community Groups

6000 people living a Positive Lifestyle


Constants

20% of youth and adults will become disengaged with society

80% of alienated people are at risk of committing a crime

20% of alienated people become re-engaged in society by their own will

90% of those arrested are put in jail and 10% are not charged

80% of youth and adults join potentially will join community groups dependent on community engagement spend

The Unemployment, Alcohol and Drugs variable can be changed to effect the rate at which disengaged people become alienated from society.

The Policing Expenditure variable can be changed to effect the number of people being arrested and also going to jail. 


Outcomes

With the variables set at minimum Unemployment, Alcohol and Drugs and maximum Community Engagement Expenditure and Policing Expenditure we see the level of crime and people in jail fall to near zero and positive lifestyle surge upwards.

An increase in the Unemployment, Alcohol and Drugs variable to 10% shows crime and people in jail increase but the ratio of people engaged in community groups is much higher.

A drop in Community Engagement Expenditure and Policing Expenditure to 50% shows a sharp increase in the amount of alienation which increases the amount of crime and then people in jail.

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.


Recommendations

If unemployment, Alcohol and Drugs remain at 10%, then maximum amounts of expenditure on Community Engagement and Policing will have the best results for people living a positive lifestyle in Bourke.
