World history is commonly understood as spanning the major geopolitical developments of about five millennia, from the first civilizations to the present. In terms such as world religion, world language, world government, and world war, world suggests international or intercontinental scope without necessarily implying participation of the entire world.
World population is the sum of all human populations at any time; similarly, world economy is the sum of the economies of all societies or countries, especially in the context of globalization. Terms like world championship, gross world product, world flags imply the sum or combination of all current-day sovereign states.
