Monitoring SDG6 on water and sanitation

Indicators 6.5.2 and 6.6.1 updated to tier I

To facilitate the implementation of the global indicator framework, the IAEG-SDGs categorizes the indicators into three different tiers. The tier categorization is based on their level of methodological development and the availability of data at the global level:

  • Tier I indicators have established methodologies and data are regularly produced by a critical mass of countries
  • Tier II indicators have established methodologies but data are not regularly produced by countries
  • Tier III indicators have methodologies that are under development

Two of the SDG 6 global indicators have recently been upgraded from tier II to tier I, following an increased data coverage:

Six of the SDG 6 global indicators are now classified as tier I, and the remaining five indicators as tier II. This development represents a big step forward, as we are increasingly able to assess the status of, and progress towards, SDG 6.

Data on the spatial extent of open waters and transboundary cooperation are available for many countries
