Which one is the world's most populated city?

Question

Because the other day I was arguing with a friend, and I was sure that Mexico City is the world's most populated city,even though Tokyo appears in most of the World Atlas as the most populated city. We need to consider the fact that the last census that ocurred in Tokyo was in 2004 , while in Mexico City in 2000.

Answer 1

Neither is the largest.

1 Seoul South Korea 10,231,000

Answer 2

These are often hard questions for statisticians because of the many ways a "city" can be defined. It's possible they are both the largest city, depending on how you look at it. Regardless, I heard sometime in the 90's that it was Mexico City, but the most recent list I saw put Tokyo at the top. That's especially impressive because it doesn't include some mammoth next-door-neighbor cities like Yokohama which altogether may have a larger population than even Tokyo. I don't know for sure.

*****
And for the record, though I'm guessing most of you know--India is a country, not a city, nor is it even the country with the highest population--though it may catch China soon.

Answer 3

China is the most populated city in the world: 1,313,973,713 (2006)

Japan is the 20th most populated city in the word : 127,463,611 (2006)

Mexico is the 11th most populated city in the world: 107,449,525 (2006)

Important note! In other surveys Jakarta is the highest and in another Tokyo is first and Mexico second.. It all depends on the reliability of the resources.

If it is to just settle the debate between you and your friend then in most surveys Tokyo is always above Mexico.

Answer 4

Mexico city

Answer 5

This site says that if you are just considering the "city" proper, that Mumbai (Bombay) India is the world's most populous city.

Cities: largest (without surrounding urban areas)

If you are considering the agglomeration, then that is a different consideration and Tokyo is the most populous when you consider the surrounding area's population.

Population density is another type of measurement, but I am assuming from your question that you meant total population.
