Answer:
About the same.
Step-by-step explanation:
Singapore is one of the most economically developed and wealthy countries in the world yet it uses less water per person than other similarly wealthy countries. Pakistan is not so economically developed yet it uses more water per person than similarly less economically developed countries. There is no clear relationship between economic prosperity as water usage has more to do with natural availability of water more than anything else. Thee might be some cases where correlation might be established but it is not proof of a clear relationship.
