Mexico City is the second largest city in the world?

[Zim Hosein]

So I'm watching Mexico Revealed on the Discover Channel narrated by Edward James Olmos and he says that Mexico City is the second largest city in the world! :Q I wonder what number one is, anyone know how this rating is calculated?

Definitely rates as one of the most polluted major cities in the world.

Tokyo be number one.

I always thought it Sao Paolo [sic?] or Mexico City was number 2.

It probably is if you try to approximate the number of homeless men, women, and children.

So from what I gather thus far, the ratings are calculated by area and not population correct?

Mexico City was the largest a few years ago.
