War Mortality and Casualty Measurement

Distinguishes battle deaths, total military deaths (incl. disease) and total war mortality (incl. civilians); measurements differ by an order of magnitude or more.

Definitions

• Battle deaths: combatants killed in combat (COW, UCDP/PRIO; Lacina & Gleditsch 2005).
• Total military deaths: adds disease and captivity; Wilson (2009) estimates for the Thirty Years' War that disease killed 2-3x as many soldiers as combat (as relayed; see event record).
• Total war mortality: adds civilian deaths from violence, famine, disease (survey-based estimates: Obermeyer, Murray & Gakidou 2008 use survey data to argue that violent war deaths in modern conflicts exceed conventional battle-death counts; the paper's exact magnitude was NOT verified this session - editor to confirm before quoting any ratio).

Examples in the corpus (this patch)

| conflict | battle/military | total | note |

|---|---|---|---|

| Taiping | COW ~111,000 battle deaths (phase) | 20-30 million (published range) | ratio ~0.4-0.5% |

| Thirty Years' War | ~450,000 combat | 4.5-8 million incl. civilians | Wilson via Wikipedia (stub) |

| Napoleonic Wars | 1.8 million+ coalition military dead | civilians not included | Urlanis/Clodfelter via Wikipedia (stub) |

Data series

Inter-State War Battle Deaths 1816-2007 (COW), Intra-State War Battle Deaths 1816-2007 (COW), Deaths in State-Based Conflicts 1946-Present (UCDP/PRIO via OWID, by region), Premodern and Early-Modern Battle/War Casualty Ranges.

Long-run debate

Pinker (2011) argues violence has declined; Gat (2006) argues the long-run picture; Scheidel (2017) places mass-mobilisation wars among the great levellers. These are interpretive claims and are cited, not adopted.
