Data sources

The SDG 6 Data Portal brings together data on all the SDG 6 global indicators and other key social, economic and environmental parameters.

Based on national official data sources

Countries are the centre and starting point for all monitoring and oversee national monitoring via their national statistical system. The national statistical system comprises the National Statistical Office, line ministries and other national institutions involved in monitoring. The 2030 Agenda clearly specifies that global follow-up and review “will be primarily based on national official data sources”. Most of the data in this portal is thus coming from countries themselves.  

At the global level, data on all SDG indicators is compiled and verified by the responsible United Nations organizations, and sometimes complemented by data from other sources. These organizations are referred to as custodian agencies.

To learn more about the roles and responsibilities for SDG 6 monitoring and reporting, visit www.sdg6monitoring.org

Links to the Global SDG Indicators Framework

The custodian agencies submit country data, along with regional and global aggregates, to the United Nations Statistics Division (UNSD). UNSD publish the data in the Global SDG Indicators Database and in an annual SDG progress reports, to inform follow-up and review at the High-Level Political Forum on Sustainable Development (HLPF). The Global SDG Indicators Database includes data on the more than 230 indicators that comprises the SDG global indicator framework.

The SDG 6 Data Portal is linked to the Global SDG Indicators Database and complements it by offering more in-depth information on the SDG 6 indicators, as well as tailored-made analytical and visualization tools.

For more information about the indicators and the data

Throughout the SDG 6 Data Portal, indicators are marked with an information symbol , which you can click on to see a description and definition of the indicator.

In all maps and charts you can hover over a specific data point, to see the full name of the indicator, area name, exact data value and reporting year.

In Table page, you can see all metadata that exist for a specific data point, including more details about where the data are coming from (e.g. if the data point is coming from a country, if it is estimated or modelled, and if any adjustments have been done to it).

List of SDG 6 custodian agencies and databases

The SDG 6 Data Portal is an entry point to the wealth of water and sanitation information available within the UN system.
