Example comparison

Freshwater is a flow, not a fixed stock.

Freshwater comparisons are often misunderstood because renewable freshwater is mainly an annual flow generated inside a country, not a pile of water stored underground.

A country can have a large total renewable flow and still have a lower per-person figure if its population is very large.

What the comparison shows

This makes freshwater a good example for switching between additive totals and per-person metrics. Total renewable internal freshwater can be added across countries, while freshwater per person should be treated as a rate.

Use the app to compare both views. The total answers where the largest renewable flows are; the per-person metric changes the question to availability relative to population.
