In an emerging or developing country, which sector normally dominates water use, and by how much?

Farming dominates, often taking 80% or more of the water used in the country.

How does the industrial share of water use in a developed country compare with that in a developing one?

It is much larger, commonly around half of all water used, against only a few per cent in many developing countries.

How does the farming share of water use in a developed country compare with the global picture?

It is usually well below the world average, often around a third, because industry and homes take a much bigger slice.

How does the amount of water used per person compare between richer and poorer countries?

People in developed countries use many times more each day than people in developing countries, where use can be barely enough for drinking, cooking and washing.
