Asia accounts for over half of today's megacities. By 2030 nearly 9% of the world's population will live in 41 megacities. But it's in Africa where some of the most rapid urbanisation will take place in the future.<br /><br />Daily Watch: mind-stretching short films throughout the working week.<br /><br />For more from Economist Films visit: http://films.economist.com/ <br />Check out The Economist’s full video catalogue: http://econ.st/20IehQk <br />Like The Economist on Facebook: https://www.facebook.com/TheEconomist/ <br />Follow The Economist on Twitter: https://twitter.com/theeconomist <br />Follow us on Instagram: https://www.instagram.com/theeconomist/ <br />Follow us on LINE: http://econ.st/1WXkOo6 <br />Follow us on Medium: https://medium.com/@the_economist
