thats your answer.

Answer 2

By the beginning of World War I, one-third of the world's population lived in a colony. The population of the world before WW1 was much smaller than it is today. There used to be 1.6 billion instead of +7 billion. Not only that, but there were less than 50 countries that were not under controll of another, so about 33% of all peoples lived in colonies, otherwise one-third.
