| Indicator Name | Battle-related deaths (number of people) |
| Long definition | Battle-related deaths are deaths in battle-related conflicts between warring parties in the conflict dyad (two conflict units that are parties to a conflict). Battle-related deaths refer to those deaths caused by the warring parties that can be directly related to combat. This includes battlefield fighting, guerrilla activities (e.g. hit and-run attacks/ambushes) and all kinds of bombardments of military bases, cities and villages etc. The target for the attacks is either the military forces or representatives for the parties, though there is often substantial collateral damage in the form of civilians being killed in the crossfire, indiscriminate bombings, etc. All fatalities, military as well as civilian, incurred in such situations are counted as battle-related deaths. |

| Statistical concept and methodology | Methodology: The dataset is constructed by automatically filtering and aggregating the UCDP Georeferenced Event Dataset from the incident level to the conflict/dyad-year level, and then joining this with additional conflict-year data from related UCDP datasets. Source material is gathered in a two-pass system: first, global newswire reporting is reviewed, followed by targeted searches in local and specialized sources such as local media, NGO and IGO reports, field reports, and social media. This approach ensures comprehensive coverage and cross-verification of events. Detailed procedures, including search strategies, are further described in the UCDP GED Codebook.
Statistical concept(s): The UCDP provides three estimates for battle-related deaths (best, low, and high) to account for the uncertainty inherent in conflict reporting. The "best estimate" (which is the value available in the World Development Indicators database) aggregates the most reliable numbers for all incidents each year, favoring the lower figure when sources are equally credible. The "low estimate" sums the lowest plausible figures, while the "high estimate" aggregates the highest plausible numbers, including incidents with uncertain party involvement. All estimates are based on publicly accessible sources and are subject to revision as new information emerges. |
| Development relevance | Monitoring battle-related deaths is critical for understanding the human cost of conflict and its implications for development. High levels of conflict-related mortality often coincide with displacement, destruction of infrastructure, and disruption of economic activity, which can reverse progress on poverty reduction and human development. Reliable data on conflict intensity inform policy responses aimed at peacebuilding, humanitarian assistance, and post-conflict recovery. They also support global efforts to track progress toward peace and security goals, by providing evidence for interventions that reduce violence and promote stability. |
| Limitations and exceptions | While the best estimate for battle-related deaths is considered a conservative minimum, the high estimate may still undercount actual fatalities due to unreported events, and users are cautioned that the apparent precision of the numbers does not eliminate underlying uncertainty. |
