Civil Strife Conflict Magnitudes, 1955-1970 (ICPSR 7485) RSS

Principal Investigator(s):


This data collection provides aggregate measures of the magnitude and intensity of civil conflicts that occurred between 1955-1970 in up to 115 countries. The variables were derived by aggregating and weighting the information on specific conflict events contained in CIVIL STRIFE EVENTS, 1955-1970 (ICPSR 7531). Included are measures of "scope," indexed by number of man-days of participation per 100,000 population, and "intensity," indexed by number of deaths per 10 million population. Separate and mutually exclusive sets of magnitude measures are constructed for domestic and anti-foreign conflicts, violent and non-violent political conflicts, and turmoil and rebellion. An alternative measure of intensity is calculated by weighting total deaths by number of participants, across all events, but is not combined into any magnitude scores. Three data files include five-year aggregations: Part 1 for 1955-1960, covering ten countries, Part 2 for 1961-1965, covering 115 countries, and Part 3 for 1966-1970, covering 87 countries. Two additional files provide annual aggregations: Part 4 contains data for all 115 countries for the period 1961-1970, and Part 5 includes information only for the ten countries on which data were collected for every year between 1955-1970. A related study, CONFLICT AND SOCIETY (ICPSR 7452), contains indicators for the independent variables selected to test causal relationships with these events.
