A long way to go – Estimates of combined water, sanitation and hygiene coverage for 25 sub-Saharan African countries

Abstract

Our estimates help to quantify the scale of progress required to achieve universal WASH access in low-income countries, as envisaged under the water and sanitation SDG. Monitoring and reporting changes in the proportion of the national population with access to water, sanitation and hygiene may be useful in focusing WASH policy and investments towards the areas of greatest need.
