Name Proportion of Population with access to improved sanitation (MDG 7.9)
Definition Improved sanitation facilities are defined in terms of the types of technology and levels of services that are more likely to be sanitary than unimproved technologies. Improved sanitation includes connection to a public sewers, connection to septic systems, pour-flush latrines, simple pit latrines and ventilated improved pit latrines. Not considered as improved sanitation are service or bucket latrines (where excreta is manually removed), public latrines and open latrines(WHO).
Calculation/Formula (Population using improved sanitation / Total population) x 100
Unit of Measure %
Range (eg Age) Population
Limitations This data is collected at the household level, so population values must be imputed. The collection of data on the proportion of the population using shared or public sanitation facilities, unimproved sanitation facilities and those practising open defecation, however is also important to track behavioural changes in sanitation practices.
Purpose/Rationale Access to drinking water and improved sanitation is a fundamental need and a human right vital for the dignity and health of all people. The health and economic benefits of improved water supply to households and individuals (especially children) are well documented. Both indicators are used to monitor progress towards the MDGs
