Understanding Income Elasticity of Demand
Income elasticity of demand measures how the quantity demanded of a good responds to a change in consumers' income. It is calculated as the percentage change in quantity demanded divided by the percentage change in income. The result sorts goods into categories that matter for economic forecasting and business planning. A mind map makes these categories and their examples easy to compare at a glance.
- Formula: percentage change in quantity demanded divided by percentage change in income
- Normal goods: positive elasticity, demand rises as income rises
- Inferior goods: negative elasticity, demand falls as income rises
- Luxuries: elasticity greater than one, demand grows faster than income
- Necessities: elasticity between zero and one, demand grows more slowly than income
Use the map to revise the formula, check the sign for each category, and practice classifying examples. CogniGuide can build a personalized version from your own lecture notes.

Income Elasticity Questions Answered
Common questions about the topic and about making your own map.
What does a negative income elasticity mean?
A negative income elasticity means demand falls when income rises. Goods with this property are called inferior goods, such as instant noodles or bus travel for households that can afford cars.
How is a luxury good different from a necessity?
A luxury has an income elasticity greater than one, so demand rises faster than income. A necessity has an elasticity between zero and one, so demand rises more slowly than income.
Which file types can I use to make the map?
You can upload PDF, Word (DOCX) or PowerPoint (PPTX) files, text or Markdown files, or images of your notes. You can also type the topic directly.
Can I turn the map into a quiz?
Yes. Any map can be turned into a quiz to test yourself on the formula, categories and examples. The same notes can also become flashcards.
