I've compiled a new list of the 21 largest urban agglomerations in the world, based on data from the United Nations. This newest list could be the most accurate one yet! Along with this new list, I've agglomerated all of my lists of world city population into one great new collection called World Cities; check it out!

How can this list omit Istanbul, which has an official population of over 12 million (but which is probably closer to 16 million)? Seoul is included with only 9.6 million, but not Istanbul?
Hi Geoprof! The UN shows Istanbul with less than 10 million people. I’ve added it to the list!
