About UCDP

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.

UCDP GED 1.9: 26 years of armed conflict and organised violence in Southeast Asia

The Uppsala Conflict Data Project at the Department launched on 11 June the UCDP Georeferenced Events Dataset release 1.9 (UCDP GED 1.9). The dataset covers individual incidents of armed conflict and organised violence (i.e. clashes, battles and attacks against civilians) in East and Southeastern Asia over a 26-year span covering January 1989 to December 2014.

The dataset is the second released subset of the UCDP GED after Africa (1989-2010). The next subset of GED will be released in early October

2015 and will contain the remainder of Asia as well as updated data for Africa until 2014.
