Number Crunching

I was in London for a job interview the other day and afterwards I went for a wander around the Tate Modern which had a very interesting exhibition about cities around our planet. The best statistic that was on display was this:

"Sao Paulo has a tube network 40km² for 18 million people, while London has a tube network of 140km² which serves 8 million people" - which is pretty staggering if you think about it.
