The Science of Sustainable Cities


Centre for Liveable Cities, Urban Solutions, July 2018

Underlying the extraordinary complexity and diversity of cities is an approximate simplicity. As a city increases in size, all of its various socioeconomic metrics scale in the same way no matter where you are on the planet. Through analysing data from thousands of cities in different countries, I found that when the size of a city doubles, there is an approximate 15% increase in its socioeconomic outcomes—from income, wealth and number of patents, to crime rate and number of flu cases. This scaling law is valid across the globe, although cities have evolved independently.
