Policy/Program Evaluation • U sing advanced ‘quasi - experimental’ econometric techniques • Used in conjunction with experiments (Randomised Control Trials), administrative data are particularly valuable for  Analysing long term impacts  Tracking hard-to-reach participants  Cost Benefit Analysis  Process evaluation (data from delivery of intervention, eg. case notes) Unlocking the power of Administrative Data | Tuesday, 25 July 2017 Page 8 Page 8

What proportion are heavy users (or frequent users)? Are these proportions changing over time? Or across cohorts? • Analysing and predicting service use patterns  Using advanced techniques such as “machine learning” Unlocking the power of Administrative Data | Tuesday, 25 July 2017 Page 9 Page 9

Use in conjunction with survey data to study behaviour • Linking administrative data to general survey data  Can provide accurate service usage information  Eg. take-up rates and patterns • A sampling base for specialised surveys  Use administrative data to find target population and conduct surveys  Eg. Journeys Home Survey uses Centrelink data ‘homeless’ flag to define target population Unlocking the power of Administrative Data | Tuesday, 25 July 2017 Page 10 Page 10
