Figure 9
Urban versus rural boxplots of local contributions (d i ), which sum to the national dissimilarity index. Values of local di are shown on the y-axis, whilst the numbers of contributing areal units is shown on the x-axis. Separate graphs are presented for drinking-water and sanitation access in different countries: (A) drinking-water access in Colombia; (B) sanitation access in Colombia; (C) drinking-water access in Egypt; (D) sanitation access in Egypt; (E) drinking-water access in South Africa; (F) sanitation access in South Africa. Outlying values are not shown, and the bottom and top of the box are the 25th and 75th percentiles respectively; the superimposed dashed line represents the average local contribution, d(t).
