Deaths in state-based conflicts, by type (absolute)

How it's computed: State-based conflicts only (a government is a party): PRIO Battle Deaths best estimates for 1946–1988, UCDP for 1989 onward. The two projects use similar but not identical rules, so the join at 1989 is a source break. Values exactly as published by the source (rounded). Source breaks: 1989: PRIO (1946–88) → UCDP (1989+).
