In Europe, before the outbreak of the war, the Allies had significant advantages in both population and economics. In 1938, the Western Allies (United Kingdom, France, Poland and the British Dominions) had a 30 percent larger population and a 30 percent higher gross domestic product than the European Axis powers (Germany and Italy); including colonies, the Allies had more than a 5:1 advantage in population and a nearly 2:1 advantage in GDP.. In Asia at the same time, China had roughly six times the population of Japan but only an 89 percent higher GDP; this reduces to three times the population and only a 38 percent higher GDP if Japanese colonies are included.
