The Income Elasticity of Demand is used to measure how an increase or decrease in the income of consumers affects the demand for a particular product. This relationship varies depending on the type of goods.
Goods for which the income-elasticity coefficient is relatively high and positive
inferior good
Depends on what type of good like perishable or non perishable, durable and non durable.

Elasticity is usually determined by far it can extend without breaking. A good example of something is very elastic is molten steel. When it is cooled, the elasticity is mostly removed.
inferior good
A good one
When people have more income, they will buy luxury products such as art.
normal food
Depends on what type of good like perishable or non perishable, durable and non durable.
normal food
Inferior or substitute products
The term elasticity indicates responsiveness of one variable to change in other variable.For e.g.,when variable x responds to change in variable y,variable x is said to be elastic.Likewise,demand is said to be elastic if it responds to change in price. There are three main determinants of demand,they are price of the commodity,income of the consumers,and price of the related goods.Thus,elasticity of demand means responsiveness of demand due to change in price of the commodity,income of the consumer,and price of the related gooods. Or you can say that,it measures the degree of change in the quantity demanded of the commodity in response to a given change in price of the commodity,change in consumer's income or price of the related goods. Accordingly,there are three main type of elasticities of demand: 1. Price elasticity of demand: Price elasticity of demand measures the responsiveness of demand for a commodity due to change in it's price. 2. Income elasticity of demand: It indicates the responsiveness of demand to change in consumer's income.It is the degree of change of demand to a change in consumer's income. 3. Cross elasticity of demand: It refers to change in quantity demanded of commodity x as a result of changes in the price of commodity y. Here, x and y can be either substitute goods or complementary goods).
Unitary is a reference to the type of demand elasticity. Unitary demand elasticity occurs when the elasticity of demand = 1. This indicates that the level of demand changes in-sync with the price at a 1:1 ratio.
