Just the amount by which demand falls with an increase in price is measured by the price elasticity of demand; the price elasticity of demand is measured by the percentage change in quantity demanded divided by the percentage change in price. This is called the paradox of poverty amidst plenty. Even if such data are available, there are difficulties of interpretation of it because it is not clear whether the changes in quantity demanded were the result of changes in price alone or changes in some other factors determining the demand.
