Displayed are the 12-month rolling average and median values. When the median value is significantly different from the average value, the median value will better represent when a particular category of a petition has been decided. This is because a small number of outliers can disproportionately impact the average value. The values exclude ePetitions.

The data is current as of June 1, 2022, and is updated quarterly.
