The Joint Monitoring Programme (JMP) for Water Supply and Sanitation by WHO and UNICEF is the official United Nations mechanism tasked with monitoring progress towards the Sustainable Development Goal Number 6 (SDG 6) since 2016. Previously, until 2015, JMP was tasked with monitoring the Millennium Development Goal (MDG) relating to drinking water and sanitation (MDG 7, Target 7c), which was to: "Halve, by 2015, the proportion of people without sustainable access to safe drinking-water and basic sanitation".
