Box plot of population size variations among sampling units in the 18 pre-war regions using the uniform grid cell approach (UGC 3 × 3 k) and quadtree approaches. Within each box, horizontal black lines denote median values; boxes extend from the first quartile and third quartile of each group’s distribution of values; vertical extending lines denote adjacent values. Note that the value for the Banadir region was divided by 1000 in both quadtree and UGC 3 × 3 km
