Unsafe Water Sources in Sub-Saharan Africa
Country-level unsafe water sources mortality data for Sub-Saharan Africa. Age-standardized death rates per 100,000 population from the IHME Global Burden of Disease Study.

This page presents unsafe water sources mortality data for countries in Sub-Saharan Africa, using age-standardized death rates per 100,000 population from the Institute for Health Metrics and Evaluation (IHME). Regional analysis reveals significant variation in disease burden between countries, reflecting differences in healthcare infrastructure, socioeconomic conditions, environmental risk factors, and public health policy implementation across Sub-Saharan Africa.
Sub-Saharan Africa faces the world's most acute health challenges, with the youngest population of any region, the highest burden of infectious diseases, and health systems constrained by limited financing and workforce shortages. This page explores unsafe water sources mortality patterns across Sub-Saharan Africa. The data covers death rates per 100,000 population for countries within the region, enabling comparison of national-level outcomes and identification of countries with particularly high or low burdens. Use the interactive charts and tables above to examine trends over time and drill down into individual country profiles.
The mortality estimates presented on this page are derived from the Global Burden of Disease (GBD) study, produced by the Institute for Health Metrics and Evaluation (IHME). The GBD synthesizes data from vital registration systems, verbal autopsies, cancer registries, and surveillance networks across more than 200 countries and territories. Death rates are expressed per 100,000 population and are age-standardized, which adjusts for differences in age structure between populations so that comparisons across countries and over time reflect genuine differences in mortality risk rather than demographic composition.
The dataset typically covers the period from 1990 to 2023, although availability varies by country and cause. When interpreting the figures for unsafe water sources in Sub-Saharan Africa, note that higher age-standardized rates indicate a greater mortality burden independent of whether a country's population is older or younger. Trends over time reveal whether public health interventions, economic development, and health system improvements have reduced or increased the toll of this condition in the region.
Disease-specific death rates measure the number of deaths directly attributed to unsafe water sources per 100,000 people, after accounting for age structure. These rates capture both the prevalence of the condition and the likelihood of a fatal outcome once affected. In Sub-Saharan Africa, variation across countries may reflect differences in disease prevalence, access to treatment, diagnostic capacity, and the presence of comorbidities. Examining trends alongside health expenditure and intervention coverage helps identify where policy action has been most effective.
