World War II Military vs Civilian Deaths

World War II was a truly devastating global conflict that carries the dubious honor of the largest and deadliest war in history. While the war consumed vast scores of people, the breakout of World War II Military vs Civilian deaths is probably not what you would expect.

The war officially began in 1939 with the German invasion of Poland (though the global conflict arguably began in 1931 with the Japanese invasion of China), and ended in 1945 with the Japanese surrender following the dropping of the atom bombs on Hiroshima and Nagasaki.

With sustained fighting on every continent (excluding Antarctica), it was a global event in every capacity.

As such, this conflict created a tremendous amount of loss, death and destruction. Nations and people were forever changed as a result. It even sped up the decline of the British Empire – the largest empire by land mass in history.

World War II was also unique in that (like its predecessor – World War I), the conflict forced nations to take a total war approach in order to survive.

All economic activity and production was shifted to maintain the war effort, and civilian populations and economic centers were often strategically targeted to disrupt enemy nations.

In turn, this caused a multitude of secondary effects that affected the proportion of deaths from military engagements, and civilian populations.

A common misconception regarding the war is that a majority of the deaths and casualties were from the vast array of military conflicts.

In reality, only roughly 25% (or 15 million) of the total estimated deaths from the conflict were are a result of military engagements.

Almost 75% of the total deaths in World War II were from civilians. This amounts to at least 45 million people – a staggering number. Despite the massive loss of life, due to advances in science and technology, it did not impact the overall world population by century trend.

The reasons behind this breakout are numerous, including:

  • Aerial bombing campaigns targeting civilian centers
  • War induced disease and famine
  • Mass extermination programs and genocide
  • Civilian population massacres and ship sinkings

Almost 85% of the civilian deaths were from the Soviet Union and China alone. These civilian populations were decimated, and massacres regularly occurred throughout the war

All told a minimum of roughly 60 million people died in World War II, with the military vs civilian deaths breakout of about 25% to 75%.
