WORLD FACTS – Largest Cities, Waterfalls

LARGEST CITIES OF THE WORLD
This is a controversial category as the boundaries of many cities are difficult to determine. There are actually seven different lists depending on how the area of the “city” is determined. Is it the formal municipal boundaries or the general area? This list uses the urban area, that is, the continuously built up landmass of urban development that is within a labor market. Obviously over time the actual population changes. (in millions) *Cities I have visited.
