Profiles of Perpetrators of Terrorism in the United States

PPT-US includes detailed information on organizations known to have engaged in terrorist activity against targets on the U.S. homeland between 1970 and 2016. Data included for each organization includes information on its terrorist attacks, its history and base of operations, its ideology and goals, its engagement in political and criminal activities (other than terrorism), its alliances, its network and structure, and its financial resources. PPT-US includes information on the source used to code each variable in the data set, and also includes a confidence indicator for each variable (high v. medium v. low), which reflects the reliability of the source upon which coding was based. PPT-US will be updated on a regular basis, as new information on terrorist attacks in the United States becomes available.
