It used to be the stuff of 2000AD, the comic that introduced the world to Judge Dredd and two vast crime-filled cities, Mega City One and East Meg One.
In its dystopian vision, the first mega city around New York began construction in 2030, intended to house three to four million people.
In a sign of how quickly future dystopias age, the new Times Atlas of the World lists the growing club of real mega cities, all of them with predicted populations of more than 10-million -- not by 2030, but by 2005.
According to these estimates, Tokyo -- the world's largest city -- will hit nearly 27m. São Paolo in Brazil will reach just under 20m and Mexico City 19m. Sixteen other cities are expected to exceed the 10m mark, including Bombay (Mumbai) 18m, and Dhaka in Bangladesh, 15m.
