What does a positive income elasticity of demand indicate about a good?

A positive income elasticity of demand means that as people's income increases, the demand for that good also increases. This usually indicates that the good is a normal good, which is something people tend to buy more of when they have more money. For example, if a person's income goes up and they decide to buy more organic fruits, this shows that organic fruits have a positive income elasticity. In contrast, if the demand for a good decreases as income rises, that would indicate it is an inferior good, like instant noodles. So, a positive income elasticity tells us that the good is valued more when consumers have higher incomes.
