Every legally recognized genocide – Rwanda, Srebrenica, Cambodia – clusters at or below RR = 1. The atomic bombings and Nanjing sit in the same zone.

  • Nagasaki (0.18) has the lowest RR on the chart. Unlike Hiroshima – which housed the Second General Army headquarters – Nagasaki’s bomb detonated over the Urakami Valley, an industrial district and its residential population. The military garrison of ~9,000 was largely outside the blast zone; of ~74,000 dead, only ~150 were soldiers killed at ground zero.
  • Hiroshima’s RR is itself disputed (0.59–1.5) depending on which garrison estimate you use. With ~14,000 military personnel in the blast zone, RR ≈ 0.59. But if the full Second Army garrison of ~43,000 is included, more military deaths push the RR up to ~1.5 – crossing the threshold from “mass atrocity” into “indiscriminate.”

Military vs civilian death rates in urban battles

  • Grozny II is the standout – the only urban battle where the civilian death rate (14.4%) exceeds the military rate (5.0%). Russia flattened the city while a mostly elderly civilian population remained trapped in a warzone. The RR of 0.35 puts it in the same category as other recognized genocides.
  • Manila (1945) shows what happens when a garrison fights to the last man in a dense city: the Japanese garrison was nearly annihilated (31.7%), but ~100,000 civilians died. Mosul and Raqqa (~8.5) show higher RRs – the attacking coalitions used more targeted strikes while ISIS defenders took catastrophic losses.
  • Gaza shows the widest gap between military and civilian death rates on the chart – 20.5% vs 1.28%. The civilian rate is low because the denominator is so large (2.2MM), while the military rate is high because militant forces are small(30-50K), skewing the RR lower.

  1. Do you have a link to the original? It says “hover over …” implying there is an interactive version out there?

  3. I imagine the numbers have very high variation depending upon your source for each conflict. Nonetheless great plot, would like to see it sorted by time as well

  4. I’m surprised that Normandy (which I’m assuming means the D-Day landing) had such a high civilian casualty rate! What’s going on?

  5. DeathFlameStroke on

    Wow this really puts the modern world into perspective. And the trends make sense: state-actors/interventions less dangerous than independent actors/total wat

  6. It would be cool to see this plotted over time and see a trend. I assume (and it seems like from this) that there is a trend to less civilian deaths in conflict. But obviously there are always outliers.
