World's Largest Cities

World's Largest Cities: This is a list of the world's largest cities in population, ordered by several ranking methods. Determining the world's largest cities depends on which definitions of "city" and "size" are used, and how those definitions are applied. The "size" of a city can refer its land area, but it is more typically the population. How one defines the land area of a city, however, is key to determining its population.
