Origins: Data on State-based Armed Conflict An armed conflict is a contested incompatibility that concerns government and/or territory where the use of armed force between two parties, of which at least one is the government of a state, results in at least 25 battle- related deaths in one calendar year. Published yearly in the report series States in Armed Conflict since 1987, in the SIPRI Yearbook since 1988, the Journal of Peace Research since 1993.

UCDP’s three categories of violence

2004: Yearly fatality estimates introduced in States in Armed Conflict For all three forms of violence, including battle deaths for state-based armed conflicts. UCDP Battle-Related Deaths Dataset,

2011: UCDP Georeferenced Event Data (UCDP GED) Event data on organised violence. Geocoded and disaggregated both temporally and spatially down to location-day levels. Additional geographical information on administrative divisions (two levels). Fatality estimates (best, low, high)

UCDP GED (cont.) Compatible with other UCDP data: - all events are part of UCDP types of violence (state-based, non-state, one-sided) - all events are part of UCDP conflicts and dyads - all actors are identified and are part of the UCDP Actor Dataset Compatible with PRIOGrid. Currently, a subset is available, covering all UCDP dyads in "active years" (>25 deaths/year). A release containing UCDP dyads in both active and non-active years (<25 in non-active years) is to be released in October. Second subset, Asia, is to be released in 2013.

UCDP GED derivatives Two derivatives of the UCDP have been produced: ->Standardized conflict zones (polygons) ->Raster/grid data (UCDP Raster)

2012: Expanding the Data on Non-state Conflicts Coding incompatibilities in non-state conflicts. Broader definition: water, grazing lands, political representation, lootable resources etc. Also coding external support. Pilot coding during the fall and next spring, starting with Africa.

2012: New version of the Peace agreement dataset UCDP Peace Agreement Dataset v. 1.0, , presented in Harbom, Lotta, Stina Högbladh and Peter Wallensteen “Armed Conflict and Peace Agreements.” Journal of Peace Research 43(5).
