If we separate the major powers of the Allied and Entente nations and calculate their populations, the total population of the Allied nations is 152.41 million (65.41 million + 52 million + 35 million).
In contrast, the total population of the Entente nations is 248.8 million (165 million + 44.1 million + 39.7 million).
With a difference of nearly 100 million people between 152.41 million and 248.8 million, it is evident that there is a significant population gap between the Allied and Entente nations. While a large part of this gap is due to Russia's population, it should be noted that Britain and France have vast colonies.
If we include India and African colonies, the population of the Entente nations would increase by several hundred million, placing them far ahead of the Allied nations in terms of population.
This substantial population difference indicates that the Entente nations have greater war potential.
