The two pie charts compare the proportions of water consumed by six products in 2004 and the share of total income those products generated in the same year.
Overall, water use and income shares do not correspond directly for all products: one product consumed nearly half of the water but produced a notably smaller share of income, while another used considerably less water yet contributed the largest share of revenue. A number of products show roughly proportional water-to-income relationships, whereas the smallest water users yielded very low income percentages.
More specifically, the largest single water consumer accounted for 46% of total water use but generated only 31% of income. By contrast, a product that used 28% of the water was responsible for the highest income share at 40%. A mid-sized product used 12% of water and produced the same 12% of income, and another accounted for 8% of both water use and income, indicating a direct correspondence for these items. The two smallest categories in terms of water consumption each used about 3% of the water; however, they contributed very little to income – one only about 1% and the other roughly 8% – showing that minimal resource use does not necessarily translate into proportional earnings.
In summary, while some products show parity between resource use and income, notable disparities suggest differences in productivity or market value among the products in 2004.
