Name: Organized violence by country-year: battle deaths (UCDP)
Creator: Uppsala Conflict Data Program (UCDP)

Keywords: conflict, armed-conflict, battle-deaths, ucdp, annual

Battle deaths from organized violence for 199 countries, 1989-2025, from the Uppsala Conflict Data Program (https://ucdp.uu.se/downloads/, keyless annual bulk ZIP, CC BY 4.0). Each row is one country in one year: state-based armed-conflict deaths (total and intrastate / interstate split), non-state conflict deaths, and one-sided violence killings (government / non-state group / unknown perpetrator), each as best / high / low estimates, plus cumulative totals. Method: keyless download of the versioned annual CSV; long dyad id/name strings dropped; country names mapped fail-loud to ISO alpha-3 (historical entities keep documented stable codes). Dyad-level detail lives in the companion armed-conflicts dataset. Caveats: estimates are revised in later annual releases; low-intensity violence below UCDP thresholds is not captured.
