The Uppsala Conflict Data Program records state-based conflicts, non-state conflicts, and one-sided violence, then estimates battle-related deaths. Our World in Data republishes the series as charts and maps with documentation.

How to read it

A country year is an estimate of deaths that meet UCDP’s definitions, not “all people harmed by war.” Compare trends more than single-year ranks. OWID’s war-and-peace page is the readable front door.

Caveats

Definitions exclude many civilian harms (displacement, hunger, disease). Early years and closed information environments are uncertain. Numbers are revised. This is not a map of who started a war.
