Inequalities in infrastructure availability. (A) Comparing South Africa and India based on inequality estimates from VIIRS NTLs across administrative scales (Top) and lattice grids with resolutions varying from 0.05° to 1° (Bottom). Level 1 corresponds to provinces (South Africa) and states (India), level 2 corresponds to districts, and level 3 corresponds to municipalities (South Africa) and subdistricts (India). (B) Comparing inequality levels across urban areas in India and South Africa with varying NTL thresholds. (C) Comparing rate (β) of change in inequality levels across spatial scales (based on lattice grid resolutions) between India and South Africa. Higher (lower) β implies more (less) concentrated inequality at coarse spatial scales.
