With more than 7 billion people now alive, the greatest population growth over the last century has occurred in urban areas. Now, a new series of interactive maps entitled "The Age of Megacities" and developed by software company ESRI allows us to visualize these dramatic effects and see just how this growth has shaped the geography of 10 of the world’s 28 megacities. Defined as areas with continuous urban development of over 10 million people, the number of megacities in the world is expected to increase, and while Tokyo still tops the list as the world’s largest megacity, other cities throughout Asia are quickly catching up. Find out more after the break.
