Global health context · 2019

WHO estimated about 505,000 diarrhoeal deaths attributable to unsafe drinking water, and about 1.4 million deaths attributable to broader unsafe water, sanitation and hygiene (WASH).

These are distinct rounded global estimates published in 2023, not current or country-level death counts. Their components overlap; do not add them. View WHO report and definitions

Country directory

No country is selected.

This directory contains 217 WDI economies plus 6 map-only entries (223 entries in total); 148 economies have 2024 access estimates. The map has 176 generalized country shapes. Small or unmapped economies remain selectable here. Missing values are never zero.
Resource measures and source-year comparisons2022 / 2023 / 2024 + latest

Country resource measures describe long-term annual flow and withdrawals. They do not measure water in storage or safe household supply.

Find a mapped water feature

Source editions differ: Natural Earth theme pages describe v5.0.0 (repository snapshot retrieved 4 October 2026); Global Dam Watch v1.0 was published in 2024; the transboundary aquifer map is edition 2025. Retrieval dates and publication years are not current water-level measurements.

What this edition covers

Shared map, separate subjects

All maps in this batch reuse the same 176-feature world basemap. The master country portal opens country news editions. Thematic maps open their own indicator, event and dataset records. Eight active theme tabs are linked; preserved legacy editions remain separate. Each edition states its own data coverage.

The wider 251-destination catalog remains a project target, not a count of complete editions or map shapes.

Why the large-barrier map is sparse

This map shows 119 selected barrier points from the 41,145 records in Global Dam Watch v1.0 (2024 publication). The filter is representative maximum capacity of at least 10 km³ (10 billion m³). It is a large-capacity subset, not an inventory of every dam or barrier. A country without a marker may still have many dams below the threshold or outside this extract.

These are catalogued capacity values, sometimes estimated; some points regulate natural lakes. Historical capacity is not current water storage, usable supply or confirmation that a barrier is operating today. Reservoir polygons and barrier points are separate, unmatched inventories.

For example, the retained Kakhovskaya record lists historical capacity although UNEP documents the Kakhovka dam breach on 6 June 2023. Its marker must not be read as proof of present storage or operation. UNEP’s Kakhovka assessment

Rights and geography

Crimea is assigned to Ukraine in line with internationally recognized boundaries, not current territorial control. UN General Assembly Resolution 68/262

Basemap: Natural Earth public-domain geometry, adapted to assign Crimea to Ukraine in line with internationally recognized boundaries. It is simplified and may predate boundary changes.

Names and inclusion support navigation, not a legal or political determination.
