Data Source: Department of Justice, Clemency Statistics. Data available from 1900 to April 30, 2016. (Includes the 58 clemency requests granted by President Obama on May 5, 2016). (Graph: Meredith Booker, 2016)

This graph originally appeared in President Obama’s record on clemency: A premature celebration.

The Department of Justice has tracked the number of clemency petitions received and their outcomes since 1900. Using this data which includes the 58 clemency requests granted on May 5, 2016 by President Obama, I calculated the percent of clemency petitions that were granted (including pardons, commutations, and remissions) by each president since Theodore Roosevelt.
