Map of Amhara, Oromia and SNNP Regional States showing location of clusters in the baseline-2006 (Maps 1a and 1b) and MIS 3R 2007 (Maps 2a and 2b) surveys. Clusters are color coded by proportion according to the legend. Maps 1a and 2a (net ownership), show the proportions of households in each cluster owning at least one net. Maps 2a and 2b (net use) show t he proportions of households in each cluster that were using at least one net the previous night, out of all household owning nets in the cluster. Therefore in Maps 2a and 2b, clusters where no households owned nets are not shown.
