Figure 41. The sizes of cities line up against their rank, from the largest (1 on the abscissa) to the smallest. They form a straight line, which slides upward in time as technology, standard of living, and GNP rise. The curves show the city sizes versus city rank in Europe from 1600 to 1980. The stepped line shows the distribution predicted with the constructal law. The detail in the upper-right corner shows that the size of every city matches the size of the area on which the city participates in area-to-point flows. The detail in the lower-left corner shows the predicted distribution of multiscale human settlements on the map (few large and many small). This pattern is obtained after deleting the construction lines from the upper-right detail.
