Understanding Functional Segregation and Integration. While the functional segregation (a) and structural integration (b) show a clear dependency over city size, functional integration (c) is not simply determined by how big is a city. In (d), we plot the deviation between functional and structural integration, computed as \((GCE_{funct}-GCE_{struc})/GCE_{struct}\) vs the values of flow hierarchy for the same cities computed in [74] from another dataset
