This report updates previous economic analyses conducted by the World Health Organization, using new water supply and sanitation coverage rates, costs of services, income levels and health indicators. Benefit-cost ratios (BCR) and costs are estimated to meet the MDG drinking-water and sanitation target and to attain universal access of basic services. Rural and urban areas are analysed as separate targets. The analysis utilises WSS coverage definitions of the JMP (WHO/UNICEF Joint Monitoring Programme for Water Supply and Sanitation).
