WWII: Soviet industrial output as a share of U.S. and German output 1940
In 1940, the Soviet Union produced significantly less industrial material than the United States in terms of natural resources and construction materials. The same was true when compared with Germany, apart from iron and steel; the USSR produced over double the amount of iron ore as Germany, and a similar amount of cast iron and steel. However, while the U.S. and Soviet populations were more comparable in 1940, Germany's population was around 70 million, which was 100 million fewer than the USSR; therefore the difference in per capita output was even higher in Germany than what is shown in the graph.
