Eighty years ago, 100 million people died in Europe and Asia in World War II.

The claim: about 80 years before March 2024 (i.e. WWII, 1939–45, which fits '80 years ago'), around 100 million people died in Europe and Asia in World War II. Standard historical estimates of total WWII deaths, military and civilian including war-related famine and disease, are the yardstick. True: credible estimates put the total at about 80–110 million. Mostly true: estimates are about 70–80 million, which matches the common 70–85 million range, so 100 million is a modest overstatement; or 100 million is reached only by including deaths outside Europe and Asia or after-effects at the top of the estimate range. Mostly false: mainstream estimates are clearly well below 100 million (e.g. 60–70 million is the consensus) and 100 million is an outlier figure. False: deaths were far below this (e.g. under 50 million).

   “An estimated 70 to 85 million people died in World War 2 — about 3% of the world's population.”

Statista puts estimates of total WWII deaths at about 70–85 million [E4]. Wikipedia gives a total of 60–75 million, including deaths from deprivation, famine and disease [E5]. It also breaks this down as 50–56 million direct deaths plus 19–28 million from war-related disease and famine, which together come to roughly 69–84 million [E6]. The National WWII Museum notes that estimates vary widely and that civilian deaths in China alone may have exceeded 50 million [E2]. The 100 million figure is above the common 70–85 million range, so under the criteria it counts as a modest overstatement.
