This study investigates the spatial distribution and estimation of access to improved sanitation in Kenya, utilizing household survey data from the 2008–2009 Kenya Demographic and Health Surveys and high-resolution population grids. The authors categorize households into wealth quintiles to observe disparities and apply spatial analysis methods, including excess risk, local spatial autocorrelation, and spatial interpolation, specifically Empirical Bayesian Kriging (EBK), to predict and map coverage rates. The study reveals significant disparities in sanitation access across different wealth categories and geographical regions within Kenya, with wealthier areas, particularly around Nairobi, exhibiting higher coverage. The findings suggest that future interventions should be tailored to specific wealth groups and areas with the greatest need to effectively improve sanitation access.

All the data I'm sharing comes directly from a peer-reviewed manuscript. For this educational review, I'm using brief quotations of the core findings—a common practice in articles and broadcasts. Of course, the source is linked for you below.
