Changes in distribution of ITN use by asset-wealth in sub-Saharan African countries from 2005 to 2015*. a The difference in average annual change for each country in the proportion of population that slept under an ITN the night prior to the survey in the lowest asset-wealth quintile and that of the highest (annual absolute excess change) against average annual change in the population (percentage points). b The proportion of the population for each of the DHS surveys that slept under an ITN the night prior to the survey in each of the five wealth quintiles (Q1–Q5) for Rwanda (RWA), Tanzania (TZA), and Ghana (GHA).
