Extended Data Fig. 6: Scatterplot of the quantity P(S, t) × S versus the ratio for France’s top-500 largest cities between 1875 and 2016.

From: The growth equation of cities

Extended Data Fig. 6

Each colour is a different year. We observe that the plots of all years collapse towards a unique universal function of the ratio in agreement with the result of equation (33) in Supplementary Information.
