Metric guide
Freshwater by country: renewable flow, not a buried stockpile.
Renewable internal freshwater resources estimate the annual flow of water generated within a country. It is a resource metric, but it is not the same thing as a fixed underground stock.
That makes interpretation important. A large total flow can look impressive, while freshwater per person can tell a different story in highly populated countries.
Reading the distribution
Why total flow and per-person supply diverge
The three largest renewable internal flows account for about 31% of the total represented by published observations. Brazil records about 1.3 times the Russia figure.
Population can reorder the leaders when the measure changes to freshwater per person. Neither version describes treatment capacity, seasonal variability, pollution, cross-border inflows or access within a country.
The largest renewable internal flows
Freshwater totals show annual renewable flow inside a country. The ranking can change sharply when you switch to freshwater per person because population pressure changes the interpretation.
| Rank | Country | Value | Year |
|---|---|---|---|
| 1 | Brazil | 5,661 billion m³/year | 2022 |
| 2 | Russia | 4,312 billion m³/year | 2022 |
| 3 | Canada | 2,850 billion m³/year | 2022 |
| 4 | United States of America | 2,818 billion m³/year | 2022 |
| 5 | People's Republic of China | 2,813 billion m³/year | 2022 |
| 6 | Colombia | 2,145 billion m³/year | 2022 |
| 7 | Indonesia | 2,019 billion m³/year | 2022 |
| 8 | Peru | 1,641 billion m³/year | 2022 |
| 9 | India | 1,446 billion m³/year | 2022 |
| 10 | Myanmar | 1,003 billion m³/year | 2022 |
| 11 | Chile | 885 billion m³/year | 2022 |
| 12 | Venezuela | 805 billion m³/year | 2022 |
Questions this metric can answer
- Compare countries by annual renewable freshwater flow.
- Switch to freshwater per person to account for population.
- Use the map to see how hydrology, land area and population create different patterns.
Interpretation limits
- Freshwater availability inside a country can vary sharply by region and season.
- Total renewable flow is additive, but freshwater per person is not.
- This metric should not be treated as a measure of groundwater reserves.
How to interpret an annual water-flow measure
The metric estimates the renewable water flow generated within a country over a year and is expressed in billion cubic metres. It can be summed across covered countries as a flow measure.
Freshwater per person is maintained as a separate non-additive metric. Neither series is presented as a measurement of a fixed groundwater reserve or household access.
