Global Burden of Disease Study 2021 (GBD 2021) Unsafe Sanitation Exposure Estimates 1990-2021

The Global Burden of Disease Study 2021 (GBD 2021), coordinated by the Institute for Health Metrics and Evaluation (IHME), estimated the burden of diseases, injuries, and risk factors for 204 countries and territories and selected subnational locations.

This dataset contains unsafe sanitation exposure estimates by year, location, age, sex, and primary toilet type for the years 1990-2021. Exposure to unsafe sanitation is defined based on the primary toilet type used. Toilet types include unimproved facilities (pit latrines without a slab, hanging or bucket latrines, and open defecation), and improved facilities (pit latrines with slabs, and composting toilets). Estimates include both the proportion of the population exposed and the number of individuals within the given population that are exposed. Estimates include mean, and the 95% uncertainty intervals. Only mean estimates are available for both sex.
