The animated maps that reveal in 60 seconds how cities have exploded in size over the last 130 years
They are an incredible reminder of just how quickly the world’s major cities are expanding.
These new animations show Paris, Los Angeles, São Paulo and Chicago expanding over 130 years – all condensed into a 60 second animation.
Researchers behind the project hope that making the expansion so visible they will force city planners to look ahead more.
The animations were created by the NYU Stern Urbanization Project.
The animations, created using information from The Atlas of Urban Expansion, clearly show the extremely rapid expansion in global cities in the 19th and 20th centuries.
‘Particularly striking is the growth in the latter half of the 20th century, in which many cities increased their built-up area by more than 10 times,’ said Patrick Lamson-Hall of the project.
