Well once again I did not do quite enough research.
The last post about the size of Shanghai was slightly inaccurate because the figure of 6300 square kilometers covers the whole municipality of Shanghai and not just the mostly urban areas of the city. For instance there is a long drive from the Puxi side of the Huangpu to the international airport at Pudong, but most of it is agricultural once you get out of the industrial area south of Jinqiao. We are not familiar with the northern part of the city but it may be similar. The outskirts are where you are finding more of the single family dwellings rather than the multistory buildings further into the core.
Anyway the long and short of it is that the urban area is roughly 2057 square kms.
So with this in mind we find these results as follows:
Shanghai's urban area is 14.28 times larger than Saskatoon's (for my Sask wife :) )
Shanghai is actually 18.04 times bigger than Vancouver (no this does not include Delta, Richmond, North Van, blah blah blah)
Shanghai's urban area is smaller than Vancouver metropolitan area, but with 3 times denser a population. (It sure did not look this way flying over it. It just went on and on while Vancouver seemed small by comparison. That's web stats for ya)
I could go on, but you get the picture......right??
