A me and a couple of friends were arguing awhile last thursday about the most populous and also about population density of cities, based on wikipedia I was wrong and tokyo is both more populous and had a higher population density than seoul, but based on 2007 figures the population density of seoul is higher, but the argument is useles because Karachi,Cairo,Kolkota, and Mumbai has about twice the population densities of both tokyo and seoul. The scary thing is that if we trust wikipedia the manila and alot of the other cities that comprise the metro manila have population densities that are about 2-10x higher than that of karachi, this is wierd to me and does not pass the smell test, don’t know but this is really surprising for me.
