From: The Gini coefficient as a useful measure of malaria inequality among populations
Inequality of malaria burden among countries in West Africa has not reduced between 2010 and 2018. a Malaria burden in individual West African countries was calculated as the estimated annual number of cases divided by population at risk. Estimated number of cases were as presented in the WHO World Malaria Report annexes [4], divided by the estimated population at risk (Additional file 1: Table S3). Data are plotted for all countries except Cape Verde for which numbers of cases were at or close to zero in each year. b The Gini coefficient estimates (with 95% confidence intervals) show no decreases in inequality of malaria burden among the countries over time, values of the coefficient being moderately high and remaining between 0.27 and 0.31 in all years (with overlapping 95% confidence intervals)
