Reliability

Last updated 29 October 2023

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 20.

As with all gap estimates, the tobacco tax gap estimate remains sensitive to our assumptions. We will continue to monitor and test the overall approach as we improve it in future releases.
