We seek feedback and advice about how we estimate the gap from our external and internal subject matter experts. Based on the advice, the reliability rating for this estimate is medium (with a score of 18).
The rating suggests that there is a degree of uncertainty in the estimates due to methodological constructs, data limitations and margins of error inherent in the data.
The ABS regularly revise their National Accounts data, including the CoE component. This can lead to revisions to prior year gap estimates in future updates. We will continue to review and improve our estimation process; including our understanding and estimate for the shadow economy.
