Summary
Income elasticity of demand is a concept in economics. Students learn how to calculate it and how to interpret the results.
What is elasticity
Elasticity is a ratio of percent change in one variable to the percent change in another. It measures the responsiveness of a function to changes in parameters. Several types of elasticity are used in economics.
Income elasticity of demand
Income elasticity of demand measures the percentage change in demand caused by a percent change in income. It helps classify goods as normal or inferior. It is calculated using a formula.
Calculating income elasticity
Students are shown how to calculate income elasticity of demand using given data. The formula is explained. The steps are shown in detail.
Interpreting income elasticity
Income elasticity of demand shows how sensitive the demand for a good is to an income change. The higher the income elasticity, the more sensitive demand for a good is to income changes.

- normal good
- A good whose demand varies in the same direction as income.
- inferior good
- A good whose demand varies in the opposite direction as income.
- price elasticity of demand
- Measures the percentage change in quantity demanded caused by a percent change in price.
- cross-price elasticity of demand
- Measures the percentage change in quantity demanded of one good caused by a percent change in price of another good.
