How the data is collected and processed

CSA end-to-end process

The diagram below outlines the end-to-end statistical process that the Crime Statistics Agency (CSA) takes to produce the crime data released on this website. 

Data cycle - received from Victoria Police, CSA conducts data quality then analyses the data and releases on the website.

At the beginning of the data cycle, the CSA receives data from the Victoria Police Law Enforcement Assistance Program (LEAP).

The CSA receives the raw data, checks for data quality issues and applies counting rules to produce the final CSA population datasets.

The datasets released each quarter, beginning March 2015, include:

  • Recorded criminal incidents
  • Recorded offences
  • Alleged offender incidents
  • Victim reports
  • Family incidents

The annual financial year statistical release includes the above data and statistics generated from two additional datasets:

  • Unique offenders
  • Unique victims

Once the datasets have been produced they are analysed to identify movements and potential trends in the data. The resulting aggregated statistics are then signed off by the Chief Statistician and released on the CSA website.

Data for Victoria are available on the latest crime data webpage and presented in data visualisations, as well as in the latest crime data by area. Data for these visualisations are also available in Excel format via the Download data button on the latest crime data webpage.
