The World Health Organization and United Nations Children’s Fund (WHO/UNICEF) Joint Monitoring Programme for Water Supply, Sanitation and Hygiene (JMP) produces internationally comparable estimates of progress on drinking water, sanitation and hygiene (WASH) and is responsible for global monitoring of the Sustainable Development Goal (SDG) targets related to WASH. This report presents updated national, regional and global estimates for WASH in households for the period 2000-2017.

The 2030 Agenda for Sustainable Development commits UN member states to take bold and transformative steps to ‘shift the world onto a sustainable and resilient path’, ‘realize the human rights of all’, ‘end poverty in all its forms’, and ensure ‘no one will be left behind’. The UN General Assembly will conduct its first quadrennial review of progress in September 2019. This report assesses progress in reducing inequalities in household WASH services and identifies the populations most at risk of being ‘left behind’.
