Shanghai may be the most populous city in the world, but interestingly it is less densely populated than New York city. Bombay on the other hand is a fraction of the size of Shanghai, and is therefore the most densely populated metropolitan area in the world.
So, armed with this information, you can prepare yourselves mentally for the sights, smells and congestion. As John told his family, " When you go to Anchorage, pretend each person is actually 46 people."
PS- It's true, I love graphs. :)
