Growth spurts and growing pains

Limited in size by the waters of the Arabian Sea, the island city of Mumbai is easily one of the most densely-populated cities in the world, with roughly 29,650 people per square km. It is also one of the largest: the city itself is home to approximately 13-14 million people, rising to 22 million for the greater metropolitan area.

With an already swelling population, Mumbai’s continual rapid growth makes things even more challenging. According to the World Bank, 500 families move to Mumbai each day. And, although many other cities are faced with similar challenges, few are dealing with it on the same scale as Mumbai.

Take 90 seconds to follow the traffic as it flows through Mumbai from 5:30 a.m. to midnight. Data scientist Will Geary developed TransitFlow as “a free and open-source software tool for visualizing (…) transit frequency around the world!”
