Quantity Demanded refers to how much of an economic good or service is demanded by a consumer or a group of consumers at a given period at a certain price. There are two important points related to quantity demanded which are,

• It is always expressed at a given price, in essence, different quantities are demanded at different prices.
• It is a flow which means quantity demanded doesn’t indicate a single purchase rather a continuous flow of purchases.

The given below figure represents the movement along demand curve due to changes in price, i.e. the upward movement of demand curve indicates the contraction of demand whereas a downward shift denotes the expansion of demand.
