The last few years, as our global population has exploded, our eyes have turned to the creation and growth of MegaCities. We found an interactive animation of growth forecasts we wanted to share with your classroom. Be sure to follow the link to interact with the maps and data.

“By 2025, the developing world, as we understand it now, will be home to 29 megacities. We explore the latest UN estimates and forecasts on the growth of these ‘cities on steroids’, and take a look at the challenges and opportunities MegaCities present for the tens of millions living there.”

At we curate and bring you the best geography and science resources from the web. We hope our sharing will keep you up to date on the latest science and geospatial news.
