This is a listing of the 26 most populous cities in the world (those having a population over eight million). Data are estimates from late 2005.

All population figures for the world's largest urban areas are simply estimates. There's no way to know the exact population of such a large place. If you don't like this list, you can review Largest Cities in the World - List Two, based on different methodologies. Both lists are valid estimates.
