Caution:
Certain important elements are partially missing from the Aqueduct indicator framework in the areas of water management and governance practices.
The composite index methodology is inherently lossy at the individual indicator level and in the decontextualization to enable comparisons across indicators.
This data combines and merges data with highly varied spatial resolutions and collection methodologies.
