List of Countries by Population
1907	1913	1925

This is a list of countries by population in 1913, based on territory they controlled at the time, not what they control today, therefore non-independent countries at the time are omitted from the list. Most estimate numbers are from the beginning of the year and exact population figures are for countries that held a census on various dates in the year 1913. Some countries' populations are estimated linearly based on population years from before 1913 and after 1913. A couple population figures are used from a year or two before/after 1913.
