Correlation between the fraction of wealthy individuals versus age and (a) degree k (R²=0.92), (b) k-shell (R²=0.96), (c) PageRank (R²=0.96) and (d) log₁₀CI (R²=0.93). Only those groups with population >20 are shown in the plot. The four metrics correlate well with financial status when considered with age. Further correlations are studied in Supplementary Note 6, indicating that CI could be considered as the most convenient metric out of the four due to its high resolution.
