"The statistics for petitions granted are taken from a count of clemency warrants maintained by the Office of the Pardon Attorney. Cases in which multiple forms of relief were granted are counted in only one category. Excluded from this chart are individual members of a class of persons granted pardons by proclamation, such as President Carter's proclamation granting clemency to certain Vietnam era offenders, and persons granted clemency after action by President Ford's Presidential Clemency Board." -
