Inequality of malaria prevalence among major administrative regions within four high burden countries in West Africa. a Each point represents the community prevalence of slide-positive malaria infection in children 6–59 months of age in the major administrative geographical regions within each of four countries as reported their most recent malaria indicator surveys (MIS). Data are analysed for 35 States in Nigeria from the 2015 MIS (having excluded one that did not have sufficient data) [21], 10 Regions within Ghana from the 2016 MIS [22], 13 Regions in Burkina Faso from the 2017 MIS [23], and 14 Districts in Sierra Leone from the 2016 MIS [24], as presented in Additional file 1: Table S4. b The within-country Gini coefficient of inequality was highest for Nigeria (G = 0.30, 95% CI 0.26–0.35), indicating a similar amount of variation within that country as exists among all 16 countries of West Africa. This was significantly greater variation than within Ghana or Sierra Leone
