Frequently asked
What is the biggest city in the world?
Tokyo by metropolitan area, at 37 million. By administrative city proper it is Chongqing, though that boundary encloses an area the size of Austria.
Why do city populations vary so much between sources?
Because "city" can mean the legal boundary, the continuously built-up urban area, or the commuting region. The three can differ by a factor of five for the same place.
