Territory size shows the proportion of people living with no reliable access to safe drinking water in 2015.
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
