How is water consumption per capita calculated?
Annual water consumption, measured in million cubic metres, is the gross amount of water extracted from any source, either permanently or temporarily, for a given use. It can be either diverted towards distribution networks or used directly. It includes consumption use, conveyance losses, and return flow. Total water consumption is the sum of estimated water use by the agricultural, domestic, and industrial sectors. Per capita consumption is then calculated using national population data from the United Nations Population Division for the year 2000.
