The Political Terror Scale (PTS) is computed annually by Professor Mark Gibney, Reed Wood and a group of volunteers.  It was first developed in the early 1980s, well before “terrorism” took on much of its present meaning.  The “terror” in the PTS refers to state-sanctioned killings, torture, disappearances and political imprisonment that the Political Terror Scale measures.  The data used in compiling this index comes from two different sources: the yearly country reports of Amnesty International and the US Department of State Country Reports on Human Rights Practices.
