This study looked at how much water each person typically uses through consuming goods and services from 1996 to 2005. The researchers focused on three types of water use: green, blue, and grey. They calculated how many cubic meters of water were needed per person each year for farming, manufacturing, and household use. The data breaks down water use by different sectors. The main report with more details on how they did this is available online. The findings show that people use a lot of water indirectly through what they buy, not just what they use directly at home or work.
