Schematic illustration of the proposed label propagation algorithm. The association of a hospital with a region propagates from the hospital location (P) into the different regions (V) at a rate depending on the hospital capacity S(P) and the population of the region, D(V), at each round of the iteration (k) until there are no more neighbours to propagate a label to. The direction of spread is determined by the geographical neighbourhood of each region V
