Clustering analyses of cities in United States. (A) Dendogram obtained from a divisive hierarchical clustering method to partition cities into two different groups color-coded in teal and orange. (B) Spearman correlation between eight income breaks (\(ID_{f}\)), and the average flow distance and out-strength per capita. (C) Fraction of the population using mass transit for each of the clusters. (D) Fraction of basic amenities accessible as a function of distance for 5 income breaks (\(ID_{q}\)) for each of the clusters.
