Data collection across sectors and administration levels
The SDG 6 indicators correspond to different aspects of water and sanitation, and information about these are frequently collected by different sectors.
For example, data on water use in agriculture are often collected by the Ministry of Agriculture, whereas data on drinking water quality may be collected by the Ministry of Health, and data on ambient water quality and wastewater discharge by the Ministry of Environment.
Some data are compiled by national and subnational ministries or the National Statistical Office, whereas other data are collected by non-state actors such as utilities, universities and research institutes, non-governmental organizations and citizens’ initiatives, the private sector and development partners.
The recommended methodologies for monitoring SDG 6 indicators also include very different mechanisms for harvesting data, ranging from household surveys to Earth observations.
