The Uppsala Conflict Data Program (UCDP) has recorded ongoing violent conflicts since the 1970s. The data provided is one of the most accurate and well-used data-sources on global armed conflicts and its definition of armed conflict is becoming a standard in how conflicts are systematically defined and studied.

“Organized Violence in the World 2015. An Assessment by the Uppsala Conflict Data Program”
In June, UCDP reported that the number of fatalities in armed conflict has increased substantially in recent years, and that 2014 was the most lethal year since the end of the Cold War for this category of violence. New data show that also the other two types of violence analyzed by the UCDP – conflict between non-state actors and violence targeting civilians – increased substantially in 2014.
