Understanding the interplay between urban segregation and accessibility to services with network analysis
Fig 6
Correlation heatmaps for key urban metrics across 81 cities.
The matrices show pairwise correlations between PoI-proximity, PoI-density, PoI-entropy, PoI-accessibility, closeness, and population using (a) Pearson correlation coefficients and (b) Kendall‘s tau. Colors range from –1 (blue, strong negative correlation) to 1 (red, strong positive correlation), with gray indicating near-zero correlation. Reported values indicate the corresponding correlations and p-values.
