Over half of the world's populations now live and work in cities. This trend will continue during the 21st century, creating "supercities" out of places like New York, Los Angeles, London, Moscow, Beijing, Mumbai, Mexico City and more. These supercities will become "vast, intensely urban hubs [that] will radically redefine the world's future macroeconomic and cultural landscape." These assumptions are both the inspiration and basis for a project called 19.20.21.
19.20.21.
19.20.21 is a vast, global project that will take 19 of the world's largest cities -- those that will have 20 million people in them during the 21st century -- as case studies to explore the impact of the "supercity" phenomenon. Their hope is that by better understanding population's effect on urban and business planning and its impact on consumers around the globe, they can help the world prepare for a whole new ballgame that will occur as supercities swell and affect change on the global cultural landscape. And there are a ton of things they're going to have to consider.
