By Mekete Berhanie and Chayaporn Kittinon
BCO6007 Business Analytics unit is the best choice at Victoria University Melbourne, that is if you really want to jump ahead of the crowd and serious about data visualisation and predictive analytics using SAP Lumira. The unit immerse you in the data analytics world using more than 8 tools that are currently and widely used by the industry. The last and the best tool was SAP Lumira and SAP Lumira Cloud.
We were assigned a task by Associate Professor Paul Hawking to analyse Domestic Violence using SAP Lumira. After searching and enquiring for three weeks, finally, we got two data sets from Crime Statistics Agency Victoria. When talking about domestic violence, it will refer to the violence happening in house or between family members. This blog will present the data divided by Local Government Area (LGA) from 2009 to 2014. The geography below shows the top and bottom 3 family incident rates per 100,000 populations by LGA in Victoria. Some people said living in western region is more dangerous than living in astern region, is this true?
Figure 1 The geography of top and bottom 3 incident rate in Victoria by LGA
As you can see in the map, Latrobe, Horsham and East Gippsland are the 3 LGA with the highest family incident and Queenscliff, Boroondara and Golden Plains are the 3 LGA with the lowest rate between 2009 and 2014. It can be summarized that it doesn’t matter whether you live, eastern or western area, the incidents can happen around Victoria.
Figure 2 The trend of family incident from 2009-2014
Let us have a look at the trend of family incident in Victoria, from Figure 2, it can be seen that the incident rate is kept rising. According to population data from Australian Bureau of Statistics 2015, the number of population growth in Victoria is just slightly different from year to year. There must be other factors that affects the incident rate other than population increase. From our research, the information from Victoria Police 2014 shows that there is new Act released called The Family Violence Protection Act 2008. There is a theory by experts that the incidents are still in the same rate but people did not report before as now , because the Act facilitates incident reporting.
Crime against the person incidents on the rise.
The data analysis shows that out of the top 5 family incidents in Victoria between 2009-2014 , ‘Crime against the person’ and ‘Justice procedures offences’ are the most reported family incidents to the Police. Please refer to Figure 3 below.
Figure 3 The top 5 family incident rate per year (2009-2014).
Rate = number of incidents/ERP (estimated residence Population).
There might have been a number of other factors other than The Family Violence Protection Act 2008; the other factor we looked at was education. We believed that these factors might explain why some areas have high number of family violence reported to the police than others.
Figure 4 Bottom ten educated people rate for 2011.
As it can be seen from the Graph the Areas family related incident reported with highest number are present in the bottom 10 group that has less educated population. Refer to Figure 6 below.
Figure 6 Family incident (TOP 3 and Bottom 3) rates per 100,000 for year 2011.
The exception of Queenscliff and Golden Plains which needs further research on demographic characteristics exploration compare to family incident. It might be needed to look at income data for analysis since 2008 , the biggest financial crisis event GFC (Global financial Crisis) .
Socio–Economic Indexes for Areas (SEIFA) also might give an answer to why family incident is on the rise since 2010.
