In one line
A normal good is something you buy more of when your income goes up.
Alfred Marshall — British economist (1842–1924) Alfred Marshall, who explained how demand changes with income. Image: Wikipedia
The rule
Normal goods are goods for which demand increases as a person's income increases, and decreases as income falls.
Let's understand it simply
Imagine you get extra pocket money from your parents. What do you do? You might buy more chocolates, better shoes, or go out for a movie. These are normal goods—things you buy more when you have more money. Now think of a crowded local train. If you start earning more, you might take an auto or a cab instead. The train ride is not a normal good for you anymore.
Normal Goods vs Inferior Goods
Normal Goods
Inferior Goods
What happens when income increases?
Buy more
Buy less
Example
Basmati rice
Cheap instant noodles
Meaning
Demand rises with income
Demand falls with income
How it works
You earn more money (your income increases).
You feel you can afford better things.
You start buying more of some goods (like branded clothes, better rice, or more fruits).
These goods are called normal goods because their demand rises with your income.
If your income falls, you buy less of these goods.
The story behind it
Economists noticed that people’s buying habits change with income. In the late 1800s, British economist Alfred Marshall explained this in his book. He wanted to show how demand for different goods changes when people have more or less money.
Where you see it in real life
Basmati rice: When a family earns more, they may switch from regular rice to basmati rice.
Smartphones: With a salary hike, many people upgrade from a basic phone to a smartphone.
Clothes: A student who gets a part-time job may buy branded jeans instead of local ones.
Eating out: More income means eating at restaurants instead of only home-cooked food.
Transport: People may shift from bus to auto or cab as their income grows.
Why it matters
Helps businesses know what products to sell to different income groups.
Used by the government to plan taxes and welfare schemes.
Important for understanding how the economy grows and changes.
Comes in many exam questions about demand and supply.
Common mistakes
Thinking all goods are normal goods. (Some are not! For example, cheap noodles may be bought less when you earn more.)
Mixing up normal goods and luxury goods. (All luxury goods are normal goods, but not all normal goods are luxury goods.)
Forgetting that some goods are inferior goods (you buy less of them when your income rises).
Remember it
If you buy more of something when you get richer, it’s a normal good.
Check yourself
If your father gets a salary increase, and your family starts buying more fruits, are fruits a normal good for your family? Why?
Yes, because you buy more as income increases.
What happens to the demand for normal goods if people lose their jobs?
Demand for normal goods will decrease because income has fallen.
Is a crowded city bus always a normal good? Why or why not?
No, for some people, it becomes an inferior good as they earn more and switch to better transport.
Quick recap
Normal goods are goods you buy more of when your income increases.
Demand for normal goods rises with income and falls when income drops.
Not all goods are normal; some are inferior goods.
