1955-2011 The PITF first identified over 100 "problem cases" in the world from 1955 to 2011.[2][3] Four distinct types of state failure events are included in the dataset: revolutionary wars, ethnic wars, adverse regime changes, and genocides and politicides. The Problem Set data includes the following information on each case: country, month and year of onset, month and year of ending (unless ongoing as of December 31 of the current update year), type of case, and annual codes on magnitude variables. The basic structure of the data is the "case-year," that is, there is a separate case-entry for each additional year of a multi-year episode. Only the first annual record for each event contains a brief narrative description of the event.
