Territory size shows the proportion of people living with no access to at least basic sanitation services in 2015, including pit latrines and toilets with cesspits, as well as those linked to mains sewerage systems.
This map uses data by the World Health Organization’s Global Health Observatory (Water and sanitation) (last accessed March 2018). We aim to map as complete data as possible and therefore estimate data for missing values. In some cases, missing data for very small territories is not used in the cartogram and that area is therefore omitted in the map.
Further notes on the data, as well as all modifications to the original data source are noted in our data sheets. Data for this map will soon be available as a download.Download data file
