Conflict deaths since 1400, three sources (absolute)

How it's computed

Three different sources, shown as separate lines and never spliced: Brecke's Conflict Catalog (1400–2000; all violent political conflicts ≥32 deaths/yr, including deaths from disease and starvation, deaths spread evenly over a conflict's years, unknown tolls set to 32), Correlates of War wars (1816–2014; wars ≥1,000 battle deaths/yr, sum of its four war types, computed by this site), and PRIO (1946–88) joined with UCDP (1989+) state-based conflicts (direct battle deaths, sum of types, computed by this site). Older figures are far less complete, especially outside Europe. Vertical lines mark where sources start, end or change. Zero years are left blank on the log scale. Some values are computed by this site from the sourced series (see note). Source breaks: 1816: COW starts; 1946: PRIO starts; 1989: UCDP replaces PRIO; 2000: Conflict Catalog ends.
