Displayed are 12 month rolling average and median values. When the median value is significantly different than the average value the median value will provide a better representation of when a particular category of 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 April 1, 2024, and is updated quarterly.
